Why Seamen Cannot Save?






Why Seamen Cannot Save?-Saving for Retirement from The Sea & The Ships!



It is a common observation that seamen though getting paid much higher than land lubbers do not succeed in saving for their retirement effectively. Seamen, most of them, do not think of their retirement while they are working onboard vessels until very late in the career. I have seen large number of seamen who did not save for the future and there career at sea came to a halt abruptly without sufficient notice, causing them and there families difficulties in managing day to day living.






Why can't seafarers save - Where does their money go?



Lets have a look at some of the factors that do not let seamen save money for their future and analyse where do the seamen’s earnings go! Lump Sum Income and big spending habits. Getting lump sum at the end of contract has been one of the major reason for spending unrealistically. In the earlier days of sailing it was common practice to be paid some cash advance onboard and the remaining balance of salary at the end of contract. Even today when a seafarer comes back home, he finds his bank balance healthy due to accumulated salaries, transferred monthly, from last contract onboard. He, and his dependents, holding back their expanses during the period of his absence start spending money and the bank balance starts shrinking. After completing contract on a ship, where a seaman remains confined onboard most of the time, he spends without limits and over time the same develops in seaman’s families as well. The Guilt Factor. A factor triggering extra expenditures is the guilt factor. The mariner, not available to his loved ones, tries to compensate his missed affection by ‘distributing’ his earnings. It has been observed that this tendency is very frequently misused by the benefices. The High Salary Structure. Seamen find themselves confident that even if they spend every penny of their income, they would be able to generate more due to the high salary structure at sea. And hence never bother to hold their hand on the expenditures. Inflated Standard of Living. Merchant Navy is a profession adopted mostly by the middle class .Where one finds educated individuals around without the big riches in hand. New entrants in merchant shipping from wealthy family backgrounds mostly do not stick to merchant navy for long time and quit comparatively much earlier as compared to their counter parts from middle class. With the increase in salary as a mariner steps up the carrier ladder, the standard of living gets better naturally. An inflated standard of living, much higher than his ‘near ones’, costs earnings of a mariner and end of the day every one connected to him requires increased share of it. When Will I Get My Next Ship? Uncertainty of job, where one does not know when one will be getting the next ship, after two months or two years. Unforeseen extended stay out of employment eats up all the financial resources. It also hinders one to invest money from where it may not be available at the time of need.
Plan Savings, Plan Retirement.


It is never too late to give your safe future a start, that would certainly bring you peace of mind and safe future to your family. You will be pleased you did it, you saved when you were young and energetic and it was so much easier to put some money aside for the future. The best way out would be to cut of a fixed slice from the salary when ever cash advance or final payment is received. A fixed percentage would be the best choice; however small or large may it be. I would say from 10-25%, the more the better, of the gross income should be saved for retirement so far as the seafarers are concerned. What ever percentage is put aside, consider your salary to be minus this saving; as if it never existed and was not a part of your income. After all, that is how pensions and provident funds are ‘cut’ in the salary slips on the shore! This saving may be put into a safe saving scheme where the actual invested sum remains guaranteed safe, that is, saving certificates, prize bonds etc. Next comes a pension plan and life insurance. Some insurance companies provide policies that combine both above features. Such investments consist of a pension plan or a policy where amount invested plus benefits is returned on completion of the term. The actual sum invested remains safe. Maintaining a insurance policy is like keeping a spare tyre in your car when leaving for a long journey. It brings peace of mind and trust that if anything happens to you your family will be taken care of. I myself, while serving at sea, realised this fact very late but however started to invest in an insurance policy and have never repented it. Only important thing is that one must go for a very reputed insurance company and investigate their previous payment records before making a final decision. Others are investments in real estate, shares and businesses; these are specialised fields and are out of scope for this essay. However, I may add that once you reach the limit of your safe investments you may only then consider investing in risky businesses. Investments in real estate, shares etc. can only work safely when you have a person of trust on shore to invest your money while you are working and earning onboard. These markets being highly liquid, do not allow risk free investments.




Career at sea is a high risk employment.


Working at sea is, apart from all safety precautions taken, a risky employment where the chances of having an accident is much higher than many normal jobs. On oil tankers, even in dry-dock, we routinely hear about people dieing from gas inhalations. It reminds me about a chief officer i heard about , while I was serving as Engine cadet. He had a Master’s Certificate of Competency and was very ambitious. The vessel was in dry-dock. After lunch break this chief officer, company's superintendent and a surveyor went down in a cargo tank. Chief officer was ahead of them all. He suddenly collapsed and the same time the portable gas meter sounded its alarm. Superintendent tried to lift chief officer and started to move up the tank ladder, but collapsed as well.


The surveyor who was still following managed to escape to deck. By the time B.A. parties went down to rescue, both had expired. There are more dangers to life lurking, as compared to shore, while one is serving on a ship, isn’t it. Above is just one accident, many similarly ones can be traced in newspapers and by the word of mouth. Let me remind that on FOC ships, where most of us work, the compensations are not very affective and where they are present, procedures involved are very slow. If you are not doing it already, go ahead and give yourself and your family a safe future. Save – before it is too late.

The Sea / Shore Working Hours:All are the Same!

Working ashore or at sea – difference is not much so far as the working conditions and hours at duty are concerned, especially if one is employed in transportation sector of which shipping is a part.When I look around at people working for different sectors related to merchant shipping ashore, they work long hours without having any regard for the so-called ‘normal’ working hours.
Mostly minimum manpower is used to its maximum utility without regard to any hours of work normalities. And in doing so much required weekly off days, public and national holidays etc are boldly ignored.Above is not the full colour to the picture that a seafarer thinking of coming ashore paints in his mind; the other side of coin is even more shocking – employees working extra hours, rather extra days ashore, mostly do not get paid also in addition to their regular remunerations. This is presicisely true to most of the companies providing active services to shipping business.


Let me add with confidence and certainty that ‘these companies’ include many big names serving internationally. Strange, isn’t it.On paper every thing is provided, but in practice nothing. And it is considered very normal! Of which every one is aware, it is an open secret.Traditionally there are ‘no working hours’ at sea, but these are supposed to adhered to on the shore.At least onboard ships most of the crew gets paid well, on shore most even don’t get paid for the jobs they attend onboard ships!What did you say? Can’t believe a word!Don’t ask any one; jobs are scarce and hence very dear.Forget the signed contracts.Just look closely into the routines of surveyors, ship chandlers, ship agents and the like and you will agree.

LNG Ships and there Future


An LNG carrier is a ship designed for transporting liquefied natural gas. As the LNG market is growing rapidly in the present decade, the fleet of LNG carriers is also growing rapidly.

It is widely known that LNG shipping and LNG ship financing have seen an unprecedented boom in the last few years. More than 80 LNG ships have been ordered in the last two years alone, against a current fleet size of approximately 176. The competition among ship owners for this rapidly growing market is intense. The LNG ship financing market has faced similar trends – it has grown significantly and is extremely competitive. Given current market conditions, both LNG shipping companies and financiers must wonder whether this momentum can hold and, if so, for how long. The question is whether the market will follow a cyclical trend so common to the shipping sector at large or evolve in a different way.

History

In 1914, Godfrey Cabot patented a barge to carry liquid gas, demonstrating that waterborne transportation was technically feasible. It was not until 1959, however that the Methane Pioneer, a converted cargo ship, was used to carry LNG between Lake Charles, Louisiana and the UK .
The first purpose-built ship, called the Methane Princess, went into operation in 1964 and remained in operation until 1998 when it was scrapped. To the end of 2005 a total of 203 vessels had been built and only 10 of them had yet been scrapped.
Mid decade, there is a boom in the size of the LNG fleet. The Gas Carrier Register indicates that there were more than 140 vessels on order at the world's ship yards in late 2005. Today the majority of the new vessels are in the size range of 120,000 m3 to 140,000 m3, but there are orders for ships with capacities near 270,000 m3




Containment systems

In order to transport natural gas, it is cooled to approximately -163 degrees Celsius where it condenses to a liquid at atmospheric pressure shrinking to approximately 1/600 of its original volume with a density of 420 to 490 kg/m3. The tanks onboard LNG carriers function, in effect, as big thermos containers wherein the liquid remains boiling for the duration of voyage. Some gas is removed to prevent a gradual buildup in pressure; this is known as Boil Off Gas (BOG). The latent heat of vapourization required to turn a small amount of LNG from a liquid to a gas is what keeps the remaining liquid cooled.
Recently, designs have been developed for pressurized transport systems as well, to be called pressurized natural gas (PNG) carriers, although none have yet been constructed .
At present, there are four containment systems in use for new ships. Two of the designs are of the self-supporting type. The other two are of the membrane type which are patented designs owned by Gaz Transport and Technigaz (GT&T). The trend is toward the membrane instead of the self-supporting types, most likely due to lower construction costs.




Moss tanks

This design is owned by the Norwegian company Moss Maritime and it is a spherical aluminum tank. It was developed in 1971 by Kvaerner. This is a self supporting type.

IHI prismatic

Ishikawajima-Harima Heavy Industries has developed a self supporting tank type. This tank type is very similar to the ones used on the first ship, Methane Princess. The tank is made of aluminum.

TGZ Mark III



This design was developed by Technigaz and it is of the membrane type. The first membrane consists of stainless steel with 'waffles' to absorb the thermal contraction when the tank is cooled down. Then below that there is a plywood skin which has anchor strips fixed to it and the primary membrane is welded to this. Below the plywood there is expanded foam insulation which then is stuck to the secondary membrane which in known as Triplex (Two layers of Fiberglass with a layer of tinfoil in the middle. Then below the triplex is another layer of insulation which is boned to the final layer of plywood. This plywood is then bonded to the ships inner hull.
The space between the primary and secondary membranes is called the interbarrier space and is kept filled with nitrogen at low pressure. Then the space between the secondary and the inner hull is called the insulation space and this is also kept nitrogen filled at a slightly higher pressure then the interbarrier space.
While loading these spaces cooldown and the nitrogen contracts meaning that more nitrogen must be added to maintain pressure. Once the ship has discharged and the tank begins to warm up the nitrogen expands and the pressure increases meaning that the nitrogen must be vented.
Both the interbarrier and insulation space are constantly monitored for both hydrocarbon levels and pressure of N2 to maintain a safe and healthy tank

GT96

This is Gaz Transport's tank design. The tanks consists of a primary and secondary thin membrane made of the material Invar, which has almost no thermal contraction. The insulation is constructed of plywood boxes filled with Perlite, a lightweight insulating material.






Propulsion

LNG carriers are unique in that the large majority of them are propelled by steam turbines, with new ships still being built with this propulsion method. This is because the simplest way of handling the boil off gas (BOG) is to burn it in the ships' boilers, creating enough steam to propel the ship when supplemented with additional gas from the cargo tanks. Diesel engines have largely replaced steam turbines in all other ship types, but until recently diesel engines adapted to run on BOG have not been widely utilised, even though the technology has been around since the early 1980's. However, the rapid expansion of the LNG fleet has meant that in the first decade of the 21st century there is a shortage of sea going personnel qualified to operate steam turbine ships. High prices for LNG are also driving the quest to maximise the yield from the transported cargo. Modified diesel engines burn less gas than steam turbines due to greater fuel efficiency. Combined cycle systems have also been implemented, with COGAS (COmbined Gas And Steam) electric propulsion arrangements having thermal efficiencies close to or greater than diesel engine systems. In this arrangement, the gas is burnt in a gas turbine and the waste heat from the gas turbine used to generate steam to run a supplementary steam turbine. However, recent developments have enabled the boil off gas to be re-liquified and returned to the cargo tanks, allowing conventional diesel engine propulsion systems to be utilised. All this has meant that coming into the 21st century the last refuge for steam ships could eventually disappear.


LNG Ship Propulsion: Is Diesel the Future?

The recent resurgence in LNG shipbuilding has injected new life into the debate between steam versus diesel propulsion. As the industry strives to lower costs and generate the additional power required by the new generation of super-large tankers, companies are re-evaluating these critical systems. That the steam turbine has enjoyed such success is no accident. The safe, environmentally acceptable combustion of low-pressure boil-off gas in ship boilers coupled with the low maintenance and high reliability of steam turbine machinery has provided the industry with highly dependable transportation for more than 40 years. But steam’s Achilles heel is its low fuel efficiency, which becomes more significant as fuel costs rise and tanker sizes increase.



In an initial break from steam turbine domination, France’s Chantiers de L’ Atlantique is utilizing a combination of its cruise ship propulsion and LNG containment experience to construct two diesel electric powered carriers for Gaz de France. These propulsion systems are being employed in vessels of varying sizes – the first order is for a 74,000 m3 vessel while the second is for a 153,000 m3 vessel. GdF, together with Japan’s Nippon Yusen Kaisha, are also expected to finalize an order for another 153,000 m3 ship with Chantiers soon. While more conventionally-sized carriers may be ordered with diesel engine propulsion, the shift is likely to accelerate with the advent of large vessels of 200,000 m3 and above. These ships will provide increased carrying capacity through broader beams and greater length, rather than in any significant increase in draft. The relatively shallow draft hulls will likely utilize twin screw and twin skeg design in order to deliver the required increase in propulsive power. This use of dual propellers also provides satisfactory maneuverability characteristics. For reasons related to costs and efficiency, it is unlikely that twin screw steam turbine propulsion will be employed in these larger LNG carriers, making diesel engine power the only viable alternative. Engine manufacturers and ship builders are promoting a variety of innovative arrangements, each offering different combinations of fuel efficiency, environmental benefit, maintainability and operational redundancy. Indeed, the machinery choice now available to both LNG project sponsors and prospective ship owners has never been wider. The single, slow speed two-stroke diesel engine, burning heavy fuel oil and connected directly to a fixed pitch propeller, is the marine industry’s established benchmark for optimum fuel efficiency. Coupled with re-liquefaction equipment, the slow speed engine is the standard installation for LPG vessels. While seagoing LNG re-liquefaction equipment remains unproven, suitable technology is available today and many in the industry are now ready to adopt it. However, the industry seems reluctant to adopt the single diesel engine installation with its routine maintenance requirements. Although the single engine arrangement may be acceptable in certain trades, twin slow speed engine arrangements seem more likely. Current proposals couple the slow speed engine with two full capacity re-liquefaction units to ensure that boil-off can always be accommodated. Moreover, this configuration is ideally suited to benefit from improved cargo tank insulation, thus reducing boil-off and the resulting power requirements for re-liquefaction.



Irrespective of measures to reduce boil-off, the power, and therefore the electrical generating capacity, required for re-liquefaction will remain high. In order to eliminate the need for large auxiliary diesel engine powered generators, one manufacturer is proposing twin screw slow speed diesel propulsion with twin main engine driven generators. The system includes power take off gear drives and clutches between the main engines and generators. Additional clutches on the main propeller shafts allow the generators to be utilized in port and controllable pitch propellers permit constant shaft speeds for 60 Hz power generation while at sea. Although the system sounds complicated, it provides an attractive combination of flexibility, redundancy and efficiency in propulsion and power generation. It is similar to the proven machinery arrangement in some North Sea oil shuttle and Alaskan trade tankers with the electrical power driving LNG re-liquefaction and cargo pumping equipment rather than dynamic positioning and oil pumping hardware. This arrangement would also have two full capacity re-liquefaction units. A third slow speed two-stroke diesel option involves a single engine converted to operate on high-pressure injected gas together with a small quantity of pilot diesel fuel. This arrangement also requires a very large auxiliary electrical capacity to power the high-pressure gas compressor required for gas injection. A trial engine has been operating ashore for several years, but it has not been tested under true marine environment conditions. The engine would be directly coupled to a fixed pitch propeller and therefore unable to consume boil-off gas in port. This would be handled either by a single full capacity re-liquefaction unit or a gas combustor, sometimes referred to as a rapid oxidizer. Both would be installed as part of the machinery package. All of these options are likely to incorporate electronically controlled, camshaft-less 2-stroke engines that are now entering the market and offering considerable advances in performance especially in controlling emissions when burning heavy fuel oil.
There are also several alternative arrangements available utilizing medium speed 4-stroke diesel engines, which offer improved fuel efficiency when compared with steam turbine machinery, but not quite so much as the slow speed 2-strokes. They are well suited for burning low-pressure gas, thus combining efficiency with environmental benefits. Some operators believe that it is preferable to deal with the boil-off by low-pressure combustion in a 4-stroke engine rather than engaging in the high gas pressures required for re-liquefaction or injection in a 2-stroke engine. The 4-stroke system favored by many involves a number (typically four) of identical dual fuel engines driving high voltage generators in a central power station concept.

This is the system currently being installed by Chantiers de l’Atlantique in the vessels being built for GdF and, except for the gas burning capability, it is similar to the power plant installations in most of today’s new cruise liners. Vessel propulsion is typically by two electric motors either geared to a single fixed pitch propeller or driving two such propellers in a twin screw arrangement. A rapid oxidizer is provided to dispose of any excess boil-off, thereby minimizing environmental pollution. The fuel required to provide pilot ignition in the engines, or to supplement boil-off gas, is marine diesel (MDO) rather than HFO diesel. This eliminates the need for fuel heating, heavy oil purifying and other handling systems. Although not yielding the highest possible fuel efficiency, this arrangement combines relatively safe low-pressure gas handling, operational and maintenance flexibility, simplified fuel oil requirements and low environmental emissions. Proponents also suggest that it may provide shipbuilders with opportunity to reduce building dock time due to elimination of the need to install and align heavy diesel engine machinery bedplates with propeller shafting. The multi-engine 4-stroke dual fuel diesel electric power station concept could also be coupled with electric podded propulsors with commercial names such as Azipods or Mermaid pods. These are already widely used in the cruise ship industry where the ability to remove machinery from the hull allows more revenue earning cabins to be installed. However, placing large main propulsion electric motors outside the hull (i.e., underwater) has its own challenges and their reliability to date has been less than that required by the LNG trade. The diesel electric power station concept has a further advantage in that LNG vessels are now very much all-electric. Most of the machinery which was originally powered by steam – such as mooring equipment, gas compressors and ballast pumps – is now all driven by electric motors yielding further fuel efficiencies.



Irrespective of any move to diesel engines, the fact remains that there are more than 60 steam turbine powered LNG ships currently on order. Each one of these vessels has an anticipated operational life of at least 40 years. This guarantees that steam turbine propulsion will dominate LNG shipping for many years to come and provide employment for another generation of steam engineers. The diesel engine will most certainly proliferate as vessel sizes grow. However, this propulsion system may never achieve the same dominance now enjoyed by steam turbines since the continuing development of gas turbines could create a wider range of choices for LNG ship builders.

Floating factory could change future of LNG

Called Excelsior, the massive red-hulled ship -- almost two football fields in length and 15 stories high -- is a signature piece in the world's first offshore liquefied natural gas port, which began operating here last year.
The ship holds enough super-cooled gas in its tanks and labyrinth of gray pipes to heat about 30,000 homes for a year. But the ship's critical attribute is the ability to turn that liquid back into a vapor at sea and pump it into an underwater pipe that carries the gas to shore.
As fears swirl over the risk of a catastrophic accident or terrorist attack at LNG terminals on land, many see such floating factories as a safer alternative for meeting surging energy demand in the United States. Two offshore LNG ports have been proposed off Gloucester, including one by Texas-based Excelerate Energy LLC, the company that charters Excelsior and owns the port in the Gulf.
There is significant opposition to the Gulf terminal and other proposed LNG deepwater ports nearby because they can take in more than 135 million gallons of the warm Gulf water a day to vaporize the liquefied gas, killing billions of fish eggs and larvae in the process. But the companies proposing the terminals off Massachusetts say they have modified the onboard vaporization process to dramatically decrease the water used, and some Bay State environmentalists and politicians are giving tempered support to the proposals.

Ghost ships

Historically, the term has been used to refer to reported sightings of apparitions over water that have appeared in the form of maritime sailing ships, often after having previously been known to have sunk, or to derelict vessels found floating with no crew. In fiction, ghost ships have often been vessels crewed by some manner of spectral or non-living beings.


The Flying Dutchman :

According to folklore, the Flying Dutchman is a ghost ship that can never go home, doomed to sail the oceans forever. The Flying Dutchman is usually spotted from afar, sometimes glowing with ghostly light. If she is hailed by another ship, her crew will often try to send messages to land, to people long since dead. The sight of this phantom ship is reckoned by seafarers to be a portent of doom.

Jian Seng:

The Jian Seng is a ghost ship, an 80 meter tanker of unknown origin that was spotted drifting 180km south-west of Weipa, Queensland in the Gulf of Carpentaria by an Australian Coastwatch aeroplane in 2006. Photographs were taken and analysed at the Australian Customs Service, who dispatched the Australian Customs vessel Storm Bay immediately.
The Storm Bay arrived during the night and waited until morning before launching a tender to board the vessel which was drifting in uncharted waters. There was no sign of recent human activity found aboard, nor any signs that it had been engaged in illegal fishing or people smuggling. A spokesman for Australian Customs addressed the media on March 24, 2006 stating that they had been unable to obtain documentary evidence of its registration or origin port at this stage, but materials recovered indicated the vessel was the Jian Seng, though the name and identifying features had been painted over.
A large quantity of rice was found on board, leading the boarding party to believe the vessel was probably used as a resupply ship for fishing boats with food and fuel in waters outside the Australian exclusive economic zone which had broken tow and drifted to its current position. The boarding party asserted that it had been adrift for an exceptionally long time before being found, and that the engines were inoperable and incapable of being restarted. The boarding party also reported that it was drifting slowly southwards. The ship had been extensively stripped, suggesting that it may have been on its way to a scrapyard when its towline broke.
The patrol boat Storm Bay monitored the ship for several days before a decision was made to tow it to the nearest harbor. A salvage tug towed the ship to Weipa, on Cape York, and oily water on the ship which posed an environmental hazard was removed. Since no owner of the ship could ever be located, it was towed to deep water on April 21, 2006 and scuttled.

Bel Amica

The Bel Amica is a ghost ship discovered off the coast of island of Sardinia near Punta Volpe on August 24, 2006. The Italian Coast Guard discovered the ship without having any apparent crew on board. The crew boarded the vessel and steered it away from rocks and shallow waters which it was headed towards. Once inside, they discovered a half-eaten meal of Egyptian food, French maps of North African seas, a pile of clothes, and the flag of Luxembourg.
The ship has been described as a "classic style" schooner never seen in Italy before.[1] It also was found never to have been registered in Italy nor any other country as the investigation was being done. The only identification aboard the ship was a wooden tablet or "plaque" as described in some papers that read "Bel Amica", a likely misspelling of "Good Friend" (the phrase needs an additional "L" to read properly in modern Italian).[2]
Shortly after the original reports, Italian newspapers reported the owner had been found. Franc Rouayrux, from Luxembourg, was identified as the owner of the vessel. It had been left anchored in deep water for somewhat nebulous reasons, and the owner stated that he had expected to return to the yacht after returning home to address an emergency. The Italian press reported that an attempt to avoid steep taxation of luxury vessels may have been involved.[3]
Many reports at the time identified the Bel Amica as a schooner. This term is frequently associated with sailing ships from the pre-steamship era; however, it is simply a technical name for the layout of the sails. Schooners of many sizes are in current production. The misidentification of this modern yacht as an antique ship deepened the mystery and probably contributed to the brief international interest at the time.

High Aim

High Aim 6 was a ghost ship found drifting in Australian waters, an obscure and rarely covered mystery from 2003. The ship is known to have left the port of Liuchiu in Taiwan on October 31, 2002. The owner of the ship, Tsai Huang Shueh-er, spoke last with the captain in December 2002. The ship was found without its crew on January 8, 2003. What happened after the last communication remains unknown. The Vessel was registered in Taiwan and flew an Indonesian flag.[1]The vessel was found drifting in calm waters approximately 80 nautical miles east of Rowley Shoals inside the Australian Exclusive Economic Zone. The crew was missing. There was no evident reason for the abandonment: no sign of distress was found, and the crew's personal effects remained on board. The High Aim 6 had plenty of fuel and provisions and no sign of a struggle could be found. Initial concerns that the ship had been carrying illegal immigrants were dismissed when the contents of the hold proved to be rotting fish. The ship was equipped for long-line fishing.
When the ship was first sighted five days before being boarded, its motor was running and it was underway. At the time of the boarding, the engine was dead and the rudder was locked, causing the ship to drift in one direction.
The High Aim 6 was towed to Broome, where subsequent forensic examination was conducted. Despite a search of some 7,300 nautical miles, no trace of crew was ever found.



The Reality Check:

1775: The Octavius, an English trading ship returning from China, was found drifting off the coast of Greenland in 1775. The captain's log showed that the ship had attempted the Northwest Passage, which had never been successfully traversed, in 1762. The ship and the bodies of her frozen crew apparently completed the passage after drifting among the pack ice for 13 years.

1872: The Mary Celeste, perhaps the most historically famous derelict, was found abandoned between Portugal (mainland) and Portugal's Azores archipelago. It was devoid of all crew, but was completely intact. While Arthur Conan Doyle's story "J. Habakuk Jephson's Statement" based on this ship added some strange phenomena to the tale (such as that the tea found in the mess hall was still hot), the fact remained that the last log entry was 11 days prior to the discovery of the ship.

1921: The Carroll A. Deering, a five-masted cargo schooner, was found stranded on a beach on Diamond Shoals, North Carolina. The ship's final voyage had been the subject of much debate and controversy (see main article), and was investigated by six Departments of the US government, largely because it was one of dozens of ships that sank or went missing within a relatively short period of time. While paranormal explanations have been advanced, the theories of mutiny or piracy are considered much more likely.

1931: The Baychimo was abandoned in the Arctic Ocean when it became trapped in pack ice and was thought doomed to sink, but remained afloat and was sighted numerous times over the next 38 years without ever being salvaged.

1933: A lifeboat from the 1906 wreck of the passenger steamship SS Valencia off the southwest coast of Vancouver Island was found floating in the area in remarkably good condition 27 years after the sinking. Sailors have also reported seeing the ship itself in the area in the years following the sinking, often as an apparition that followed down the coast.

1948: Many ships responded to the desperate Morse code messages from the Dutch freighter Ourang Medan. The ship was found adrift off Indonesia with all of its crew dead. The boarding party found the entire crew "frozen, teeth baring, gaping at the sun." Before the ship could be towed to a home port, the ship exploded and sank. The reason for the deaths are still unexplained today.

1955: The MV Joyita was discovered abandoned in the Pacific.

2003: High Aim 6 - was a ghost ship found drifting in Australian waters with no crew on board. Despite an extensive search, no trace of the crew was ever found.

2006: The tanker Jian Seng was found off the coast of Weipa, Queensland Australia in March. Its origin or owner could not be determined and it was scuttled in April.

2006: In August the "Bel Amica" (which is one "L" short of the modern Italian spelling of "Good Friend") was discovered off the coast of Sardinia.The Coast Guard crew that discovered the ship found half eaten Egyptian meals, French maps of North African seas, and a flag of Luxembourg on board.

2007: A 12-metre catamaran, the Kaz II, was discovered unmanned off the coast of Queensland, northeast Australia in April[4]. The yacht, which had left Airlie Beach on Sunday 15 April, was spotted about 80 nautical miles off Townsville, near the outer Great Barrier Reef on the following Wednesday. When boarded on Friday, the engine was running, a laptop was running, the radio and GPS were working and a meal was set to eat, but the three-man crew were not on board. All the sails were up but one was badly shredded, while three life jackets and survival equipment, including an emergency beacon, were found on board. A search for the crew was abandoned on Sunday 22nd as it was considered unlikely that anyone could have survived for that period of time.



In film

In 2003, Walt Disney Pictures released the first film in the trilogy Pirates of the Caribbean, the plots of which involve the ghost ships The Black Pearl and The Flying Dutchman. The films are based on the Disney theme park attraction of the same name.

The 2002 horror film Ghost Ship involves a stranded Italian ocean liner named Antonia Graza, lost at sea since 21 May 1962. The ship is boarded by a salvage crew, who shortly afterward encounter the ghostly apparitions of murdered passengers.

In 2001 the Sci Fi Channel broadcast Lost Voyage, a Sci Fi Pictures original film about the return of a derelict luxury ship, the Corona Queen, missing 25 years earlier, investigated by the son of one of the missing passengers.

The 1997 science fiction film Event Horizon involved a spaceship that had taken an experimental voyage into another dimension, only to vanish with no trace. It returns to our solar system seven years later with no crew, life support not operating, and the recordings of the flight scrambled. The investigating team soon encounters an alien presence brought back from the other dimension.

Numerous episodes of the various Star Trek series deal with abandoned ships discovered adrift. Notable examples are "The Tholian Web" (Star Trek), "The Naked Now", and "Booby Trap" (Star Trek: The Next Generation).

Captain James Cook :The worlds explorer



Captain James Cook FRS RN (27 October 1728 (O.S.) – 14 February 1779) was an English explorer, navigator and cartographer. Ultimately rising to the rank of Captain in the Royal Navy, Cook was the first to map Newfoundland prior to making three voyages to the Pacific Ocean during which he achieved the first European contact with the eastern coastline of Australia, the European discovery of the Hawaiian Islands, and the first recorded circumnavigation of New Zealand.

Cook's 12 years sailing around the Pacific Ocean contributed much to European knowledge of the area. Several islands such as Sandwich Islands (Hawaii) were encountered for the first time by Europeans, and his more accurate navigational charting of large areas of the Pacific was a major achievement.
To create accurate maps, latitude and longitude need to be known. Navigators had been able to work out latitude accurately for centuries by measuring the angle of the sun or a star above the horizon with a sextant. But longitude was more difficult to measure accurately because it requires precise knowledge of the time difference between points on the surface of the earth. Earth turns a full 360 degrees relative to the sun each day. Thus longitude corresponds to time: 15 degrees every hour, or 1 degree every 4 minutes.
Cook gathered accurate longitude measurements during his first voyage due to his navigational skills, the help of astronomer Charles Green and by using the newly published Nautical Almanac tables, via the lunar distance method — measuring the angular distance from the moon to either the sun during daytime or one of eight bright stars during nighttime to determine the time at the Royal Observatory, Greenwich, and comparing that to his local time determined via the altitude of the sun, moon, or stars. On his second voyage Cook used the K1 chronometer made by Larcum Kendall, which was the shape of a large pocket watch, 13 cm (5 inches) in diameter. It was a copy of the H4 clock made by John Harrison, which proved to be the first to keep accurate time at sea when used on the ship Deptford's journey to Jamaica, 1761-1762.
There were several artists on the first voyage. Sydney Parkinson was involved in many of the drawings, completing 264 drawings before his death near the end of the voyage. They were of immense scientific value to British botanists. Cook's second expedition included the artist William Hodges, who produced notable landscape paintings of Tahiti, Easter Island, and other locations.

Cook was accompanied by many scientists, whose observations and discoveries added to the importance of the voyages. Joseph Banks, a botanist, went on the first voyage along with fellow botanist Daniel Solander from Sweden. Between them they collected over 3,000 plant species. Banks became one of the strongest promoters of the settlement of Australia by the British, based on his own personal observations.
Ever the observer, Cook was the first European to have extensive contact with various people of the Pacific. He sailed to many islands near the Philippines and even to smaller, more remote islands in the South Pacific. He correctly concluded there was a relationship among all the people in the Pacific, despite their being separated by thousands of miles of ocean (see Malayo-Polynesian languages). In New Zealand the coming of Cook is often used to signify the onset of colonisation.
The first tertiary education institution in North Queensland, Australia was named after him, with James Cook University opening in Townsville in 1970. Numerous other institutions, landmarks and place names reflect the importance of Cook's contribution to knowledge of geography.
The site where he was killed in Hawaii is marked by a white obelisk and is roped off. It is about 10 feet-square in area. This land, though in Hawaii, has been given to the United Kingdom. Therefore, the site is officially a part of the UK (much as an embassy in a country is part of the nation operating the embassy.) With the jurisdictions reversed exactly the same sort of situation exists at Runnymede where the U.S. has extraterritorial jurisdiction over a monument to John F. Kennedy.
Cook appeared on a United States coin, the 1928 Hawaiian Sesquicentennial half dollar. Minted during the celebration marking the 150th anniversary of his "discovery" of the islands, its low mintage (10,008) has made this example of Early United States commemorative coins both scarce and expensive.
Tributes abound, too, back at 'home' in post-industrial Middlesbrough, England, and include a primary school, shopping square and Claes Oldenburg public artwork, the Bottle 'O Notes, while the James Cook University Hospital, a teaching hospital in Marton, was also named after him. Marton is also the location of the Captain Cook Birthplace Museum. The Royal Research Ship RRS James Cook was built in 2006 to replace the RRS Charles Darwin in the UK's Royal Research Fleet.
His contributions were recognized during his era. In 1779, when the American colonies were at war with Britain in their war for independence, Benjamin Franklin wrote to captains of American warships at sea,[9] recommending that if they came into contact with Cook's vessel, to:
not consider her an enemy, nor suffer any plunder to be made of the effects contained in her, nor obstruct her immediate return to England by detaining her or sending her into any other part of Europe or to America; but that you treat the said Captain Cook and his people with all civility and kindness, . . . as common friends to mankind.

After service in the British merchant navy as a teenager, Cook joined the Royal Navy in 1755. He saw action in the Seven Years' War, and subsequently surveyed and mapped much of the entrance to the Saint Lawrence River during the siege of Quebec. This allowed General Wolfe to make his famous stealth attack on the Plains of Abraham, and helped to bring Cook to the attention of the Admiralty and Royal Society. This notice came at a crucial moment both in his personal career and in the direction of British overseas discovery, and led to his commission in 1766 as commander of HM Bark Endeavour for the first of three Pacific voyages.
Cook accurately charted many areas and recorded several islands and coastlines on Europeans' maps for the first time. His achievements can be attributed to a combination of seamanship, superior surveying and cartographic skills, courage in exploring dangerous locations to confirm the facts (for example dipping into the Antarctic circle repeatedly and exploring around the Great Barrier Reef), an ability to lead men in adverse conditions, and boldness both with regard to the extent of his explorations and his willingness to exceed the instructions given to him by the Admiralty.
Cook died in Hawaii in a fight with Hawaiians during his third exploratory voyage in the Pacific in 1779

Early life
Cook was born in relatively humble circumstances in the village of Marton in North Yorkshire, today a suburb belonging to the town of Middlesbrough. He was baptised in the local church of St. Cuthberts, Marton, where today his name can be seen in the church register. Cook was one of five children of James Cook, a Scottish farm labourer, and his locally-born wife Grace. As a child, Cook moved with his family to Airey Holme farm at Great Ayton, where he was educated at the local school (now a museum), his studies financed by his father's employer. At 13 he began work with his father, who managed the farm. Cook's Cottage, his parent's last home and which he may have visited, is now in Melbourne.
In 1745, when he was 16, Cook left home to be apprenticed in a grocery/haberdashery in the fishing village of Staithes. According to legend, Cook first felt the lure of the sea while gazing out of the shop window.
After a year and a half in Staithes, William Sanderson, the shop's owner, found Cook unsuited to the trade. Sanderson took Cook to the nearby port town of Whitby and introduced him to John and Henry Walker. The Walkers were prominent local ship-owners and Quakers, and were in the coal trade. Cook was taken on as a merchant navy apprentice in their small fleet of vessels plying coal along the English coast. His first assignment was aboard the collier Freelove, and he spent several years on this and various other coasters sailing between the Tyne and London.
For this new apprenticeship, Cook applied himself to the study of algebra, geometry, trigonometry, navigation, astronomy, skills he would need one day to command his own ship.
His three-year apprenticeship completed, Cook began working on trading ships in the Baltic Sea. He soon progressed through the merchant navy ranks, starting with his 1752 promotion to Mate (officer in charge of navigation) aboard the collier brig Friendship. In 1755 he was offered command of this vessel, but within the month he volunteered for service in the British Royal Navy.
In 1755, the Kingdom of Great Britain was re-arming for what was to become the Seven Years' War. Cook saw that his career could advance more quickly in military service. However, this required starting again in the naval hierarchy, and on June 17 he began as able seaman aboard HMS Eagle under the command of Captain Hugh Palliser. He was very quickly promoted to Master's Mate. By 1757, within two years of joining the Royal Navy, he passed his master's examination qualifying him to navigate and handle a ship of the King's fleet.
Start of Royal Navy career
During the Seven Years' War, he participated in the siege of Quebec City before the Battle of the Plains of Abraham in 1759. He showed a talent for surveying and cartography and was responsible for mapping much of the entrance to the Saint Lawrence River during the siege, allowing General Wolfe to make his famous stealth attack on the Plains of Abraham.
Cook's surveying skills were put to good use in the 1760s, mapping the jagged coast of Newfoundland. Cook surveyed the northwest stretch in 1763 and 1764, the south coast between the Burin Peninsula and Cape Ray in 1765 and 1766, and the west coast in 1767. Cook’s five seasons in Newfoundland produced the first large-scale and accurate maps of the island’s coasts; they also gave Cook his mastery of practical surveying, achieved under often adverse conditions, and brought him to the attention of the Admiralty and Royal Society at a crucial moment both in his personal career and in the direction of British overseas discovery.
Following on from his exertions in Newfoundland, it was at this time that Cook wrote, he intended to go not only:
"... farther than any man has been before me, but as far as I think it is possible for a man to go."


First voyage (1768–71)


In 1766, the Royal Society hired Cook to travel to the Pacific Ocean to observe and record the transit of Venus across the Sun. He sailed from England in 1768, rounded Cape Horn and continued westward across the Pacific to arrive at Tahiti on April 13, 1769, where the observations were to be made. However, the result of the observations were not as conclusive or accurate as had been hoped. Cook later mapped the complete New Zealand coastline, making only some minor errors. He then sailed west, reaching the southeastern coast of the Australian continent on 19 April 1770, and in doing so his expedition became the first recorded Europeans to have encountered its eastern coastline. On April 29 Cook and crew made their first landfall on the continent at a place now known as Kurnell, which he named Botany Bay after the unique specimens retrieved by the botanists Joseph Banks, Daniel Solander and Herman Spöring. He continued northwards, and a mishap occurred when Endeavour ran aground on a shoal of the Great Barrier Reef, on June 11, 1770. The ship was seriously damaged and his voyage was delayed almost seven weeks while repairs were carried out on the beach (near the docks of modern Cooktown, at the mouth of the Endeavour River). Once repairs were complete the voyage continued, sailing through Torres Strait and on 22 August he landed on Possession Island, where he claimed the entire coastline he had just explored. He returned to England via the Cape of Good Hope and Saint Helena, arriving on the 12th June, 1771.


Second voyage (1772–75)



Shortly after his return, Cook was promoted from Master to Commander. Then once again he was commissioned by the Royal Society to search for the mythical Terra Australis. On his first voyage, Cook had demonstrated by circumnavigating New Zealand that it was not attached to a larger landmass to the south; and although by charting almost the entire eastern coastline of Australia he had shown it to be continental in size, the Terra Australis being sought was supposed to lie further to the south. Despite this evidence to the contrary Dalrymple and others of the Royal Society still believed that this massive southern continent should exist.
Cook commanded HMS Resolution on this voyage, while Tobias Furneaux commanded its companion ship, HMS Adventure. Cook's expedition circumnavigated the globe at a very high southern latitude, becoming one of the first to cross the Antarctic Circle on January 17, 1773, reaching 71°10' south. He also discovered South Georgia and the South Sandwich Islands. In the Antarctic fog, Resolution and Adventure became separated. Furneaux made his way to New Zealand, where he lost some of his men following a fight with Māori, and eventually sailed back to Britain, while Cook continued to explore the Antarctic.
Cook almost discovered the mainland of Antarctica, but turned back north towards Tahiti to resupply his ship. He then resumed his southward course in a second fruitless attempt to find the supposed continent. On this leg of the voyage he brought with him a young Tahitian named Omai, who proved to be somewhat less knowledgeable about the Pacific than Tupaia had been on the first voyage. On his return voyage, in 1774 he landed at the Friendly Islands, Easter Island, Norfolk Island, New Caledonia and Vanuatu. His reports upon his return home put to rest the popular myth of Terra Australis.
Another accomplishment of the second voyage was the successful employment of the K1 chronometer, which enabled Cook to calculate his longitudinal position with much greater accuracy. Cook's log was full of praise for the watch and the charts of the southern Pacific Ocean he made with its use were remarkably accurate - so much so that copies of them were still in use in the mid 20th century.
Upon his return, Cook was promoted to the rank of Captain and given an honorary retirement from the Royal Navy, as an officer in the Greenwich Hospital. His fame now extended beyond the Admiralty and he was also made a Fellow of the Royal Society and awarded the Copley Gold Medal, painted by Nathaniel Dance-Holland, dined with James Boswell and described in the House of Lords as "the first navigator in Europe".[3] But he could not be kept away from the sea. A third voyage was planned to find the Northwest Passage. Cook travelled to the Pacific and hoped to travel east to the Atlantic, while a simultaneous voyage travelled the opposite way.


Third voyage (1776–79)


On his last voyage, Cook once again commanded HMS Resolution, while Captain Charles Clerke commanded HMS Discovery. Ostensibly the voyage was planned to return Omai to Tahiti; this is what the general public believed, as he had become a favourite curiosity in London. After returning Omai, Cook travelled north and in 1778 became the first European to visit the Hawaiian Islands, which, in passing and after initial landfall in January 1778 at Waimea harbour, Kauai, he named the "Sandwich Islands" after the fourth Earl of Sandwich, the acting First Lord of the Admiralty.
From there, he travelled east to explore the west coast of North America, landing near the First Nations village at Yuquot in Nootka Sound on Vancouver Island, although he unknowingly sailed past the Strait of Juan de Fuca. He explored and mapped the coast from California all the way to the Bering Strait, on the way identifying what came to be known as Cook Inlet in Alaska. It has been said that, in a single visit, Cook charted the majority of the American North West coastline on world maps for the first time, determined the extent of Alaska and closed the gaps of Russian (from the West) and Spanish (from the South) exploratory probes of the Northern limits of the Pacific.[4]
The Bering Strait proved to be impassable, although he made several attempts to sail through it. He became increasingly frustrated on this voyage, and perhaps began to suffer from a stomach ailment; it is speculated that this led to irrational behaviour towards his crew, such as forcing them to eat walrus meat, which they found inedible. (It has also been suggested that Cook had been exhibiting irrational behavior since early in the voyage).
Cook returned to Hawaii in 1779. After sailing around the archipelago for some eight weeks, he made landfall at Kealakekua Bay, on what is now the 'Big Island' of Hawaii. There is some discussion by recent historians that Cook's arrival coincided by quirk of fate with a season of worship for the Polynesian god Lono, (Makahiki). Indeed the form of Cook's ship HMS Resolution (more particularly the mast formation, sails and rigging) resembled certain significant artifacts that formed part of the season of worship. Similarly, Cook's clockwise route around the islands before making landfall resembled the processions that took place in a clockwise direction around the island during the Lono festivals. For these reasons the arrival, it is thought, led to Cook's (and to a limited extent, his crew's) initial deification by the natives, who treated him with great reverence as possibly an incarnation of Lono himself. This interpretation of the natives' reaction, though, has been called into question.
After a month's stay, Cook got under sail again to resume his exploration of the Northern Pacific. However, shortly after leaving the Big Island, the foremast on the Resolution broke requiring the ships' return to Kealakekua Bay for repairs. The return to the islands by Cook's expedition was unexpected on the part of the Hawaiians and as the season of Lono had recently ended, tensions rose and a number of quarrels broke out between the two camps. On February 14 at Kealakekua Bay, some Hawaiians stole one of Cook's small boats. Normally, as thefts were quite common in Tahiti and the other islands, Cook would have taken hostages until the stolen articles were returned. Indeed, he planned to take hostage the Chief of Hawaii, Kalaniopu'u. However, his stomach ailment and increasingly irrational behaviour led to an altercation with a large crowd of Hawaiians gathered on the beach when he went ashore to retrieve the goods. The villagers, angered by his strict insistence on getting back a pair of tongs, and hearing that another British search party had killed one of their chiefs, began to attack with spears and stones. In the ensuing skirmish, shots were fired at the Hawaiians but their woven war shields protected them, and Cook's men had to retreat to the beach. As Cook turned his back to help launch the boats, he was struck on the head by the villagers and then stabbed to death as he fell on his face in the surf.[7] The Hawaiians dragged his body away.

It is thought that Cook's return to Hawaii outside the season of worship for Lono, which was synonymous with 'peace', and thus in the season of 'war' (being dedicated to Kū, god of war) may have upset the equilibrium and fostered an atmosphere of resentment and aggression from the local population. Coupled with a jaded grasp of native diplomacy and a burgeoning but limited understanding of local politics, Cook may have inadvertently contributed to the tensions that ultimately conspired in his demise.
The esteem in which he was nevertheless held by the natives resulted in his body being retained by their chiefs and elders (possibly, as some claim, for partial human consumption, though this remains contentious) and the flesh cut and roasted from his bones. Some of Cook's remains, disclosing some corroborating evidence to this effect, were eventually returned to the British for a formal burial at sea following an appeal by the crew.
Clerke took over the expedition and made a final attempt to pass through the Bering Strait. Resolution and Discovery returned home in 1780. Cook's account of his voyage was completed by Captain James King.


Death of Cook
Death of Cook is the name of several paintings depicting the 1779 death of British explorer and European discoverer of the Hawaiian Islands, Captain James Cook. Most of these paintings seem to go back to an original by John Cleveley, painted in 1784, although other versions, like that of John Webber, stood model for later copies too. Such artworks were reproduced in paint and engraving over the course of modern world history. The much more famous reproductions, like the one at the Honolulu Academy of Arts (allegedly based on the Cleveley version), often depicted Cook as a peacemaker trying to stop the fighting between his sailors and the native Hawaiians that they had challenged in combat.
In 2004 however, the original Cleveley painting was discovered in a private collection belonging to an English family. It was known that Cleveley based his original painting on eye-witness accounts of the actual event. The original happened to depict Cook also involved in hand-to-hand combat with the native Hawaiians. The discovery of the original painting has not changed the way historians think about Cook's relationship with the native Hawaiians, as Cook's violent nature was reported upon by his contemporaries. According to Richard Hough's 1997 biography of Cook the journals of those on the expeditions with Cook also describe him as clearly ordering that those under his command treat all native people with respect and friendship and many times he punished his crew for crimes against the natives, even minor offenses. Cook's own journals often show a man deeply concerned for them and their future. The English's nearly universal experience with them of constant theft from the ships and encampments often lead to bad relations which sometimes became violent as happened when Cook was killed in Hawaii. He was accompanied by only 10 men when they were attacked by approximately 300 Hawaiians. After four of them and at least as many natives were killed the English could not reload before being overrun and fled to the sea. Cook walked defiantly toward the sea with his hand behind his head to protect it from thrown rocks, one of which struck him and knocked him down. He was then repeatedly clubbed and stabbed to death at the water's edge in plain view of a small boat of English who failed to help him due to the cowardice of the man in command, Lieutenant John Williamson. After the death of Cook the English exacted much revenge with cannon fire and burning of the village for punishment and in an attempt to get the natives to return the bodies. Only a small portion of Cook's charred remains were returned and later buried at sea.
