”Fraudulent entries in ORBs is rising exponentially

The Oily Water Separator (OWS) was first mandated for installation on ships by the International Maritime Organization (IMO) in
1974. At the same time, a requirement was established for maintenance
of an Oil Record Book (ORB) to keep track of use of the OWS and
disposal of the ship’s oily waste. The OWS was originally designed to
reduce the oil in discharge water to 100 parts per million. Ships could
discharge waste water that contained up to that level of oil so long as
the ship was underway, at least a certain distance offshore, and not in a
particularly sensitive area. The equipment operated reasonably well and
the program was largely self-enforced. Life was good.
In 1992, though, the discharge standard was strengthened to 15 parts
per million. Problems surfaced immediately. The OWS equipment was
not operating properly. Filters regularly clogged and discharges ceased
frequently. Meanwhile, waste water levels in the bilges were rising. It
turned out that many OWS manufacturers had merely fine-tuned their
old 100 ppm devices to achieve the new 15 ppm requirement. This was
achievable on a test platform in the factory, but frequently failed on a
ship at sea. Life was no longer good, at least for chief engineers, who had
to manage this problem while keeping the ship operating.
Things changed drastically on February 1
st
1993, when a routine
U.S. Coast Guard air patrol observed a long sheen of oil streaming
astern of a cruise ship on the high seas off Florida. Review of the ship’s
ORB when the ship arrived in port revealed that no entry had been
made relative to this discharge. When the flag state declined to take
action, the U.S. government charged with cruise ship operator with
making a false statement to a federal official. The operator litigated
this and a related case, arguing, among other things, that there was no
violation of federal law since both the discharge and the ORB entry were
made while the ship was on the high seas. The court held, though, that
the false statement occurred when the ORB was presented for Coast
Guard examination while the ship was in a U.S. port. After losing the
procedural motions, the cruise ship operator settled this criminal charge
by payment of USD 9 million and, in the related case, by payment of
USD 18 million. No other shipowner or operator has litigated an ORB
charge since those highly expensive events. Life was no longer good for
chief engineers, masters, or shipowners.
Many in the maritime industry are beginning to view the ORB as
a signed confession. The number of prosecutions in the United States
for fraudulent entries in ORBs is rising exponentially and fines have

recently skyrocketed. In the years 1998 through 2001, research has
revealed one prosecution in each year for oil record book violations. In
2002, there were seven prosecutions – and four of those were against
individual chief engineers. In 2003, nine prosecutions, four of which
were again against individual chief engineers. In 2004, there were seven
prosecutions, and only two were directed at individual chief engineers.
Through September, nine companies and nine individuals have been
prosecuted during 2005. Criminal fines to date have totaled USD
82,716,000. Shipping companies are also being required to implement
court-supervised compliance programs.

Under federal law, a false statement consists of
1) making a statement orally or in writing;
2) when the statement is false or misleading;
3) the false or misleading information is material;
4) the statement or concealment was made knowingly; and
5) the statement was made to a federal official engaged in
performance of his or her duty.
Here, the statement was made in the ORB, which the ship is required
to maintain and is required to present to the Coast Guard upon request
when the ship is in U.S. waters. If the federal government can prove that
the chief engineer or another senior person in the ship knew that one or
more entries in the ORB (which the person in charge of the operation is
required to initial) is false and that the false entry was made knowingly,
then the company can be held criminally responsible. The individuals
making the false entry (generally the chief engineer and the master) can
also be held criminally responsible.
Because the ORB bears the initials of the person making each entry
and the signature of the master, the document serves the purpose of a
signed confession, for which there is almost no defense.
To minimize the likelihood that the chief engineer or another engineering officer on the ship improperly disposes of the waste oil, the
company should take positive steps to ensure that the OWS is operating
properly and is well maintained. This will often require replacement of
the OWS, particularly if the unit is more than about seven years old. The
chief engineer should be clearly informed (preferably in writing) that his
or her primary goal in this regard is to properly handle and dispose of
waste oil and that the general admonition to minimize expenses does
Record Book entries regarding discharge of
oily water.
As can be seen from the descriptions of
the foregoing cases, (1) both owners in their
corporate forms and individuals are being
charged and convicted, and (2) none of the
cases are going to trial, but are being resolved
by means of guilty pleas, that is, admissions
in court and on the public record that the
defendants have engaged in the criminal conduct
with which they have been charged, and are prepared to
endure the consequences. In the face of the possibility of even more severe
sanctions than those following a guilty plea,
defendants have not been willing to take these
matters to trial.not apply to this goal. Also,
personnel should be clearly advised of the requirement that log and record
entries are to be made contemporaneously
with the event and are to be accurate.
A preferred method of accomplishing
both tasks is for the company to institute a
maritime compliance program. Federal law
provides that, if a company has a qualifying
compliance program in place and a violation
occurs regardless, the company will be entitled to a major reduction in sentence. One
major cruise ship company benefi ted from
this provision when it was proven that some
of its personnel had engaged in improper
discharge of waste oil and falsifi cation of
the ORB. Both the Department of Justice
and the Environmental Protection Agency
(EPA) have written policies providing that,
in appropriate cases, they will forego criminal prosecution for companies with compliance programs. The EPA has exercised such
forbearance in the past, although not yet in
a maritime context.
The bottom line is that, for a shipowner
or operator to avoid handing the federal
government a signed confession in the form
of an oil record book with false entries, the
owner or operator must impress upon its
engineering offi cers that they are to properly maintain and operate the OWS and
to make accurate and contemporaneous
entries in the ORB. The engineering offi cers, particularly the chief engineer, must be
given every incentive to do the right thing
and no incentive to do the wrong thing.

The Consequences

Criminal convictions, including plea agreements, can bring with them not only substantial fi nes, but possible prison terms, the banning of personnel from entering the United
States or serving on vessels calling at United
States ports, and stringent environmental
compliance programs which the United States
government will supervise. Investigators will
also detain the vessels for indefi nite periods
and crew members may be held as material
witnesses long after the ship is allowed to sail.
The fi nancial implications of such detentions
of ships and personnel are obvious and substantial.

Recent incident:
Transmar Shipping Co, S.A., the operator of the cargo ship M/V New Fortune, pleaded
guilty in federal court in Oakland today to failing to maintain an Oil Record Book and making a false
statement to the U.S. Coast Guard, United States Attorney Joseph P. Russoniello announced. The vessel’s
Chief Engineer Dimitrios Dimitrakis pleaded guilty to failing to maintain an Oil Record Book, and the
Second Engineer Volodymyr Dombrovskyy pleaded guilty to aiding and abetting the failure to maintain an
accurate Oil Record Book. These guilty pleas stem from the defendants’ overboard disposal of oil residue,
sludge, oil and oily mixtures into the ocean and their subsequent efforts to conceal these discharges by
falsifying their onboard records.
“This prosecution evidences our determination to protect the environment from the unlawful discharge of
waste oil from ships, a major source of pollution to ocean and inland waters,” said U.S. Attorney Joseph P.
Russoniello. “Companies need to understand that there are criminal consequences for attempting to deceive
government regulators by providing false documents to authorities to avoid compliance with environmental
laws.”
According to Court documents, the M/V New Fortune is a 26,136 gross ton ocean-going bulk cargo ship that
is registered in the Marshall Islands. It was engaged in the carriage of bulk products in world-wide
commerce. Following the ship’s trans-Pacific journey from South Korea to the Port of Oakland, U.S. Coast
Guard inspectors boarded the vessel for a routine inspection. At that time, crew members advised the
inspectors that illegal activities were taking place onboard, and came forward to reveal that the crew was
using a “magic hose” to dispose of the vessels’ oil-containing waste overboard, bypassing the vessel’s
pollution prevention equipment. Further investigation by the Coast Guard and the U.S. Environmental
Protection Agency’s Criminal Investigation Division revealed waste oil in the overboard piping of the M/V
New Fortune and also uncovered evidence of false entries made in the vessel’s Oil Record Book, a documen
required by MARPOL, a treaty ratified and implemented by the United States and other countries.
MARPOL, which stands for marine pollution, and U.S. law limit the oil content of overboard discharges
from ships to not more than 15 parts per million. To ensure compliance, MARPOL requires that all transfers
of sludge, oil contaminated bilge water, and overboard discharges of bilge water, be fully and accurately
recorded in the Oil Record Book.
“We consider failure to comply with MARPOL to be an insult to the seas and the citizens of the world. We
work hard to make clear we have no tolerance for such behavior and we will hold accountable those that
violate MARPOL,” said Capt. Paul Gugg, commander of the Coast Guard's San Francisco Sector.
Court documents further state that Chief Engineer Dimitrakis and Second Engineer Dombrovskyy were
onboard the M/V New Fortune from March 1, 2009 through Feb. 16, 2010, when the ship came into port in Oakland. Dimitrakis held overall responsibility for the engine room where the bypass hose was used and the
pollution prevention equipment was located and Dombrovskyy worked in the engine room under Dimitrakis.
Dimitrakis and Dombrovskyy admitted that they regularly ordered M/V New Fortune crew members to
bypass the vessel’s oil pollution prevention equipment through the illegal use of a bypass hose and
discharged oil-contaminated bilge water and sludge directly into the ocean. Dimitrakis also admitted that he
concealed this disposal by regularly making false entries and omissions in the vessel’s Oil Record Book.
Dombrovskyy admitted that he disposed of the “magic hose” before entering the waters of the United States
in order to conceal that they had used it to discharge of sludge and bilge water directly overboard.
According to court documents, on a number of occasions, Dimitrakis and Dombrovskyy ordered crew
members to operate the bypass hose and pumps at night while on the high seas. Dimitrakis and
Dombrovskyy ordered crew members to disconnect and hide the bypass hose prior to entering United States
waters and ports, as well as ports in other locations.
According to court documents, Dimitrakis made false entries into the Oil Record Book indicating that the
ship’s Oil Water Separator was being used, creating the overall false impression that the vessel was being
properly operated and that they were properly maintaining the vessel’s Oil Record Book. No entries were
made in the ship’s Oil Record Book indicating the direct discharge of bilge water and sludge from the ship
into the ocean.
Court documents further state that on Feb. 16, 2010, during the Coast Guard’s inspection, the M/V New
Fortune crew presented the false Oil Record Book to the U.S. Coast Guard during the vessels’ United States
port call in Oakland.
After accepting the guilty plea, U.S. District Judge D. Lowell Jensen sentenced Transmar to pay a fine of
$750,000, an additional community service payment of $100,000, and ordered it to follow an environmental
compliance plan agreed to by the parties. TRANSMAR is required to develop, fund, and implement a
comprehensive, fleet-wide environmental compliance plan to ensure future compliance aboard all of its
vessels. As part of the plan, Transmar will, among other things, designate a corporate compliance manager to
oversee implementation of the plan, develop an environmental manual for all ships, fully train employees,
and hire an outside environmental consultant who will conduct compliance audits of Transmar ships.
Dombrovskyy was sentenced to two years probation, a $500 fine, and a $100 special assessment.
Dimitrakis is scheduled to be sentenced on Sept. 3, 2010, before the Honorable D. Lowell Jensen in
Oakland. The maximum statutory penalty for a violation of 33 U.S.C. § 1908(a) is six years imprisonment
and a $250,000 fine. However, any sentence following conviction would be imposed by the court after
consideration of the U.S. Sentencing Guidelines and the federal statute governing the imposition of a
sentence, 18 U.S.C. § 3553.
This case is being prosecuted by Chinhayi Cadet, Assistant U.S. Attorney for the Northern District of
California, and Trial Attorney Lana Pettus for the Environmental Crimes Section in the Justice Department’s
Environment and Natural Resources Division with the assistance of Jeanne Carstensen. The prosecution is
the result of an investigation by the U.S. Coast Guard Investigative Service, the U.S. Coast Guard Sector San
Francisco Port State Control Inspections Office, and the U.S. Environmental Protection Agency Criminal
Investigation Division, with assistance from the U.S. Coast Guard District Eleven Legal Office.

MARITIME MOTIVATOR - VOL-2

Beauty lies in the Difficulties.

Life Onboard a ship can be very beautiful and can be very difficult. We must appreciate the beauty so much that the difficulties cannot bring us down.

The way we deal with shipboard stress is not to avoid them. The way is to successfully deal with those difficulties and to overwhelm them.

Be more persistent than your most persistent problems. Use your creativity, your flexibility, your ingenuity and your passion to make your way forward no matter what.

Treasure the beauty in even the smallest, most seemingly insignificant things. Connect with the abundance that is woven through every fiber of life.

See each moment as an opportunity to make a small difference. Those small steps you make forward will soon add up to create big results.

Life can at times be difficult, but so what? The immense beauty of sea and possibilities for joy are worth far more than all the troubles combined.

MARITIME MOTIVATOR


Motivation is the inner power or energy that pushes one toward performing a certain action. Motivation has much to do with desire and ambition, and if they are absent, motivation is absent too. Often, a person has the desire and ambition to get something done or achieve a certain goal, but lacks the push, the initiative and the willingness to take action. This shows a lack of motivation and inner drive. Motivation strengthens the ambition, increases initiative and gives direction, courage, energy and the persistence to follow one's goals. A motivated person takes action and do whatever it needs to achieve his/her goals. Motivation is usually strong, when one has a vision, a clear mental image of a certain situation or achievement, and also a strong desire to materialize it. In this case motivation pushes one forward, toward taking action and making the vision a reality. Motivation can be applied to every action and goal. There could be motivation to study a foreign language, to get good grades at school, bake a cake, write a poem, take a walk everyday, make more money, get a better job, buy a new house, own a business or become a writer, a doctor or a lawyer. Motivation is present whenever there is a clear vision, precise knowledge of what one wants to do, a strong desire and faith in one's abilities. Actually, motivation is one of the most important keys to success. Lack of motivation either does not bring results or brings only mediocre results, whereas motivation brings faster, better and bigger results. Compare a student who lacks motivation and who hardly studies, to a student who is highly motivated, and who devotes many hours to his studies. They will get absolutely different grades. Seafarers , who are socially cut off from Land needs it the most, to perform there task at hands in adverse condition at sea and growing commercial pressures. MARITIME MOTIVATOR is just an attempt to boost there morals. Nandkishore Gitte.

MARITIME MOTIVATOR - VOL-1



What is like working onboard? For some, it is just standing and watching the traffic at sea, Taking rounds in Engine room, Job satisfaction. For others, it's caring for a there family. Paying for kids tuitions , planning for future/retirements.

Work is the business of life. We all do it, whether we collect a paycheck or not. It is what keeps us alive, and what moves us forward. There is no menial work. It is all important. Weather we are Captain, Chief engineer. Boson, or a cadet.

In all work, there is the potential for fulfillment, because there is the opportunity to make a difference. It may be keeping watch, navigating, chipping on deck, or painting bulkhead. The more of yourself you put into your work, the more your work will accomplish. Put your hands into your work, and it will keep you alive. Put your mind into it, and it will provide a life. Put your essence into it, and it will bring enormous rewards.

You affect the value of your work, not so much by what you do, but by what you give to the effort.

Ancient Shipbuilding Techniques








The study of ancient shipbuilding techniques and their
development in the ancient era has mainly been based upon a
technical analysis of the archaeological and historical evidence
available, concluding normally in a sort of logical and linear
evolution. However, the new perspective given to the research
of ancient maritime societies by the growing discipline of maritime
archaeology and the study of the most recent archaeological finds
leas us to reconsider the development of nautical technology
in Antiquity and to understand the importance of the social
component in its historical evolution.


Introduction

The different techniques used during the Ancient World in
shipbuilding have long been assumed to manifest a sort of
linear “evolution”. The research on ancient watercrafts and the
field of maritime archaeology in itself, until very recently, have
studied and interpreted boats remains with a mere
technical approach. Hence, the overview that has traditionally
been given of the development of naval technology in the Ancient
Mediterranean, from the first evidences of bundle rafts in Egypt
to the construction of big plank boats, firstly using sewn joints
as The Cheops Ship (2600 BC) and then the mortise.and tenon
fastenings technique, used forinstance in The Kyrenia Ship in
Cyprus (300BC), is that of a consecutive and related process.


In the last decade, however, the maritime archaeology discipline
and the study of ancient boats have broadened its scope looking
for the social patterns and anthropological traits behind the
evident material culture.Furthermore, new archaeological finds
and other sort of evidences are showing us that the nautical
scene of the Ancient Mediterranean Sea was rather more complex
than we had thought. Although it appears evident that shipbuilding
techniques among mediterranean communities moved towards
improvements in the manoeuvrability and the rigidity of the vessels,
we often find that technology is restricted by the society that
uses it, together with its socioeconomic systems, and also by
the environment where they interact (Westerdahl, 1992 & 1994; Adams,
2001). Factors such as religion, tradition, political or economic
system, which are in continuous relation with themselves, shape and
constrain the ideas, symbols and uses that a specific society gives
to its watercrafts.


Despite technological progresses in the mediterranean region new
evidence shows that sewn-plank boats continued to be widely in use
from the late centuries BC, in Roman times and even earlier, to the
eleventh century AD, right into the medieval period . At the same
time, from the first century BC we can perceive a progressive
abandonment in the use of the mortise and tenon fastenings, gaining
crucial importance the internal structure
of framing and longitudinal timbers. This appears to be clear in
the evidence from the seventh century AD. By the beginning of the
eleventh century AD the old shipbuilding technique of shell-first
construction was completely abandoned and shifted to frame-first
techniques, which were to be of great influence in the new social
and political situation of Europe from the medieval period onwards.


Throughout this article it will be examined how the continuity of
sewn fastenings and the ship construction to framing-first
techniques evidence on the transition from shell-fir
scan tell us about the social implications that their raised the
shipbuilding techniques used in the An use entails. For that
purpose it will be briefly sum ancient Mediterranean until the
Medieval Period and some of the evidence we have of relationship
between ship technology and them, analysing some specific examples
to approach this better understanding of the society in the Ancient
World.

Shipbuilding techniques & Navigation in Ancient India.

An Ancient India there existed a strange belief that if any Hindu crossed the seas, he would lose his religion. When and why this belief came into being is not known. But taking a close look at out nation's maritime history we find evidence of a very large number of Indians who should have had lost their religion as they had crossed the seas to trade and build empires in distant lands.

Not only did these enterprising Indians, not lose their religion but they made India into one of the foremost maritime nations of those days and spread Indian culture overseas.

In those days India had colonies, in Cambodia (Kambuja in Sanskrit) in Java, (Chavakam or Yava dwipa) in Sumatra, in Borneo, Socotra (Sukhadhara) and even in Japan. Indian traders had established settlements in Southern China, in the Malayan Peninsula, in Arabia, in Egypt, in Persia, etc., Through the Persians and Arabs, India had cultivated trade relations with the Roman Empire.


Sanskrit and Pali literature has innumerable references to the maritime activity of Indians in ancient times. There is also one treatise in Sanskrit, named Yukti Kalpa Taru which has been compiled by a person called Bhoja Narapati. (The Yukti Kalpa Taru (YKT) had been translated and published by Prof. Aufrecht in his 'Catalogue of Sanskrit Manu scripts. An excellent study of the YKT had been undertaken by Dr. Radha Kumud Mookerji entitled 'Indian Shipping'. Published by Orient Longman, Bombay in 1912.)

A panel found at Mohenjodaro, depicting a sailing craft. Vessels were of many types Their construction is vividly described in the Yukti Kalpa Taru an ancient Indian text on Ship-building.

This treatise gives a technocratic exposition on the technique of shipbuilding. It sets forth minute details about the various types of ships, their sizes, the materials from which they were built. The Yukti Kalpa Taru sums up in a condensed form all the available information

The Yukti Kalpa Taru gives sufficient information and date to prove that in ancient times, Indian shipbuilders had a good knowledge of the materials which were used in building ships. Apart from describing the qualities of the different types of wood and their suitability in shipbuilding, the Yukti Kalpa Taru also gives an elaborate classification of ships based on their size.

The primary division is into 2 classes viz. Samanya (ordinary) and Vishesha (Special). The ordinary type for sea voyages. Ships that undertook sea voyages were classified into, Dirgha type of ships which had a long and narrow hull and the Unnata type of ships which had a higher hull.

The treatise also gives elaborate directions for decorating and furnishing the ships with a view to making them comfortable for passengers. Also mentioned are details about the internal seating and accommodation to be provided on the ships. Three classes of ships are distinguished according to their length and the position of cabins. The ships having cabins extending from one end of the deck to the other are called Sarvamandira vessels.

These ships are recommended for the transport of royal treasure and horses. The next are the Madhyamarnandira vessels which have cabins only in the middle part of their deck. these vessels are recommended for pleasure trips. And finally there is a category of Agramandira vessels, these ships were used mainly in warfare.


There were Sanskrit terms for many parts of a ship. The ship's anchor was known as Nava-Bandhan-Kilaha which literally means 'A Nail to tie up a ship' . The sail was called Vata Vastra a which means 'wind-cloth'. The hull was termed StulaBhaga i.e. an'expanded area'. The rudder was called Keni-Pata, Pata means blade; the rudder was also known as Karna which literally means a 'ear' and was so called because it used to be a hollow curved blade, as is found today in exhaust fans. The ship's keel was called Nava-Tala which means 'bottom of a ship'. The mast was known as Kupadanda, in which danda means a pole.

Even a sextant was used for navigation and was called Vruttashanga-Bhaga. But what is more surprising is that even a contrived mariner's compass was used by Indian navigators nearly 1500 to 2000 years ago. This claim is not being made in an overzealous nationalistic spirit. This has in fact been the suggestion of an European expert, Mr. J.L. Reid, who was a member of the Institute of Naval Architects and Shipbuilders in England at around the beginning of the present century. This is what Mr. Reid has said in the Bombay Gazetteer, vol. xiii., Part ii., Appendix A.

"The early Hindu astrologers are said to have used the magnet, in fixing the North and East, in laying foundations, and other religious ceremonies. The Hindu compass was an iron fish that floated in a vessel of oil and pointed to the North. The fact of this older Hindu compass seems placed beyond doubt by the Sanskrit word Maccha Yantra, or fish machine, which Molesworth gives as a name for the mariner's compass".

It is significant to note that these are the words of a foreign Naval Architect and Shipbuilding Expert. It is thus quite possible that the Maccha Yantra (fish machine) was transmitted to the west by the Arabs to give us the mariner's compass of today.


Shipbuilding in Ancient China


With a long coastline stretching along the broad water areas of Bohai, Huanghai, Donghai, and Nanhai, and bordering the world's largest ocean, the Pacific Ocean, China enjoys a special water environment. Hence, Chinese people began to engage in seafaring activities a long time ago. Chinese shipbuilding boasts an even longer history, as it began in primeval times.

As early as in the Neolithic Age (about 10,000-4,000 years ago), Chinese people had begun to made canoes and rafts, and with their courage and wisdom, had traveled the ocean. Textual research has proved that the ancient Baiyue people, who lived in Southeast China, invented the first water-bound vehicle.


During the Qin (221-206) and Han (206BC-220AD) dynasties, China's shipbuilding witnessed the first climax, when the Qin EmperorQin Shihuangorganized a fleet capable of transporting 500,000 shi (1 shi = 170 pounds /71.7 kilos) of grain in a war. As recorded in ancient books, Emperor Qin Shihuang once led a fleet composed of lou chuan (castle ships, or war ships with deck castles) for an assault on the Chu State. After the unification of all of China, he also cruised along inland rivers and navigated at sea.

By theHan Dynasty, the navy mainly composed of castle ships was much stronger. It was said that the Han government could mobilize over 2,000 castle ships and 200,000 seamen for one battle. Various kinds of warships could be found, such as Xian Deng -- an assault ship, Meng Chong -- a narrow warship for striking the enemy's warships, and Ben Ma -- a ship as fast as a galloping horse. However, the assault castle ship was still the most important among all the ships and constituted the main force of the navy. Apart from being famous, the castle ship was also the symbol for the dynasty's advanced shipbuilding techniques.

The development in shipbuilding during the Qin and Han dynasties laid a solid foundation for the progress in shipbuilding skills in the following dynasties. The Wu State of theThree Kingdoms Period(220-280) had a prosperous shipbuilding industry and once built a five-story ship that could hold up to 3,000 soldiers. TheSouthern Dynasty(420-589) could build big ships with a holding capacity of 1,000 tons in the southern areas of theYangtze River. In order to enhance the ship's speed, the great scientist of the Southern Qi Dynasty (what year; I'm unfamiliar with this dynasty) invented the manpowered paddle wheel ship. Though not as efficient as using the sail, the paddle wheel ship was still recognized as a significant invention, which provided inspiration for the improvement of ship power later on.

China's shipbuilding industry entered a period of maturity, both in quantity and quality in the Tang (618-907) and Song (960-1279) dynasties. Utilization of many shipbuilding techniques, such as the stern helm, the highly efficient propelling tool - scull, and the sails, were further improved during this period. Besides, many more advanced techniques were also created. TheSui Dynasty, though short lived, enjoyed a highly developed shipbuilding industry, with the capacity to build giantdragonboats. Assembled with mortise-and-tenon joints, the dragon boats were much stronger than those connected with iron nails or bamboo nails.


Ships built during this period were larger in body, more reasonable in configuration, and more complex in techniques. Among the various ships for use on rivers (as opposed for seas or oceans), there were plenty of ships capable of holding 600 to 700 people, with a length of over 20 zhang (about 66 meters). On some ships, vegetables were grown. During the Song Dynasty, a huge ship named Shen Zhou was made, which boasted a carrying capacity of 1,500 tons and a hull length of 31.5 zhang (about 100 meters).

Ship design at that time applied the principle of "curved side boards, broad lateral beams, and loft superstructure." Under this principle, the decks were broadened, and more cabin space was available. The V-shaped bottom greatly facilitated the sailing.

The number of ships also increased by leaps and bounces, with an obvious increase in shipbuilding yards capable of building any kinds of ships, including river boats, sea boats, warships, and so on.

Apart from the above-mentioned features, shipbuilding techniques also experienced enormous advances. Mortise-and-tenon joints were employed in assembling ships, hence greatly improving the ships' strength. China's adoption of this technology was 500 years earlier than that in European countries. The Song artisans were able to make models based on the function and use of the ships to be built, with blueprints being worked out prior to carrying out the actual construction. Ship blueprints did not appear in European until 300 to 400 years later.

The paddle wheel ship, a kind of warship that emerged during the Southern Dynasty, also got improved. The paddle wheel ship got wooden wheels installed on both sides of the hull, which greatly increased the ship's speed. Since the ancient ships were mostly sailing ships that could not easily sail against wind or water, the development of paddle wheel ships solved the problem to a certain extent.

In the early years of the Yuan Dynasty (1271-1368), there were more than 17,900 navy warships. The Yuan emperors would usually order thousands of warships to be built for a battle. Besides, there were a great many civil ships scattered all over the country. Meanwhile, Arabs' shipbuilding and navigation gradually declined. Therefore, Chinese four-mast sea boats could be seen on the Southern Sea and the Indian Ocean, taking the lead in navigation and shipbuilding.

The huge development in shipbuilding during the Yuan Dynasty laid an advantageous foundation for the building of five-mast warships, six-mast guest ships, seven-mast grain ships, eight-mast horse ships (which carried horses), and nine-mast precious ships (which carried valuable cargo) during theMing Dynasty.

China's shipbuilding reached its third climax during the Ming Dynasty (1368-1644), when an unprecedented number of ships were built by employing the well-developed shipbuilding technologies of the Tang and Song dynasties.


According to some archeological discoveries and historical records, the distribution and scale of the Ming Dynasty's shipbuilding yards represented the highest level in Chinese shipbuilding history. The main shipbuilding yards included the Longjiang Shipyard inNanjingof East China'sJiangsu Province, the Qingjiang Shipyard in Huainan of East China'sAnhui Province, and the Beiqinghe Shipyard in East China's Shangdong Province, all of which boasted a large scale. There were handicrafts workshops that produced ship accessories, such as sails, ropes, and nails, to go with the shipbuilding industry. In addition, there was also a rigorous management system concerning the check, repair, and payment of ships. It was fitting that with such a strong shipbuilding industry,Zheng He' seven voyages to the western sea became possible.

In a word, after the previous two climaxes, shipbuilding in the Ming Dynasty experienced further improvement in shipbuilding technologies. The great achievements in shipbuilding during the Ming Dynasty represented an enormous contribution by the Chinese people to world civilization and human development.


Shipbuilding techniques in the Ancient Mediterranean



There is little evidence for the use of watercrafts in the Mediterranean before the Bronze Age. Iconographic and literary studies, however,suggest that during the Mesolithic times complex log rafts, as the ones that Hiram of Tyre used to send cedar to Solomon (I Kings 5:23), buoyed boats, as the ones described
by Pliny used to transport elephant from Calabria to Sicily (NH 8. 16) or bundle rafts, as we see in some depictions in Malta or, for example, on a Minoan gold ring found at Mochlos, Crete (McGrail, 2001, pag.103; Johnstone, 1988, pag. 59) were in use. These bundle rafts, which were widely used in Early Egypt and Mesopotamia, continued in use in many parts of the Mediterranean during all the
classical period as it is clearly shown in a graffito dated to the Roman Age from She´arim, in Israel, and in a boat representation from the
rock-painti ngs group of La Laja Alta, Southern Spain, dated probably to the end of the Second Millennium BC (Almagro-Gorbea, 1988, pag.

398; Barroso, 1980, pag. 42; Dams, 1984; Luzón, 1988, pag. 455). Nowadays, bundle rafts still in use in some marginal parts of the Mediterranean, in societies with long-standing indigenous traditions as for example in the Oristano Region, in Sardinia (McGrail, 2001, pag. 105; Riccardi, 1988, pag. 275-286).

By Neolithic times it is probable that seagoing extended logboats or even simple plank vessels were technologically possible and took part in the colonization of Islands as Crete, carrying the obsidian, a clear indicator of early sea
voyages (Johnstone, 1988, pag. 55). The direct evidence for these crafts, nevertheless, has to be found much later. Although there is evidence
for seagoing travels in the Early Bronze Age (c.3800-2000 BC) we only count with
iconographic material in order to interpret the type of vessels used at that time. The study of the lead models from Naxos, the terracotta models from Palaikastro and Mochlos or the depictions on the Cycladic “Frying Pans” suggests that the vessels used in the Early Bronze Age were either logboats extended in
height and length or planked boats with cargo capacity and probably propelled by oars and with a helmsman (McGrail, 2001, pag. 106- 111; Casson, 1995, pag. 30-39). Unfortunately, at present there are no excavated boats that
can prove or give more light on the shipbuilding
techniques used on these ships.

This iconographic and documentary evidence is more evident in the eastern Mediterranean at the beginning of 2000 BC, in what it is known as the Middle Bronze Age. This increase in the evidence comes associated to a growth in the
number of seafaring activities, especially in the Levant Coast and in Crete. It is also in this time when we find the first evidence for the use of the sail in the Mediterranean, although it was probably in use much earlier in the late
fourth millennium BC in Egypt. This first evidence is a Syrian cylinder seal from Tel el Daba (1800 BC). From these times are also the first depictions of masts and rigging features in the Mediterranean. They are on a series of Minoan seals dated to the beginning of the second millennium BC. On them, the mast appears amidships but normally the sail is not
shown. The hull used to be rounded with a higher end (may be the stern?) and they could have been propelled also by human force if
we interpret the angular lines underneath the
hull as oars (McGrail, 2001, pag. 113;
Wachsmann, 1998).

But, without doubt, the representations that have raised more discussion on the Middle Bronze Age seafaring scene are those ones found at Akrotiri, in Thera. Leaving aside the controversies about its precise chronology or about the meaning of the scene itself, we have here vessels with a flat bottom whose ends
curve upwards. The stern is slightly higher than the bow. They were probably plank boats, built with plank-first techniques. Whether if they had sewn fastenings or mortise and tenon ones, is impossible to tell from these depictions.
They could be propelled by sail, oar or paddle, and were steered by a steering oar when it was necessary (McGrail, 2001, pag. 122).
Although there have been many interpretations for the purposes of these ships (Wachsmann, 1980, pag. 287-295), their peculiarities, as for example the decoration, the stern cabin or the central awning, the old fashioned method of
propulsion (paddling) and the stern projections (Casson, 1975, pag. 3-10), suggest that they were taking part in a sort of special event or ceremony instead of being intended for long- distance crossings.

Sometimes, the practical and technical shipbuilding methodology is placed in the
background when facing profound cultur al
manifestations or needs (Adams, 2001). We can appreciate in this example how the society exerts a big influence on the use of boats, and
therefore, in the way they were depicted.

Mortise and tenon plank fastenings



The end of the Middle Bronze Age is usually
taken to be the fall down of the Minoan
“thalassocracy” based on Crete. This event is

been related to the volcanic explosion of the
Island of Thera dated to 1628 BC and by
Egyptian correlation to 1450 – 1500 BC. Thanks
to the excavation of several eastern
Mediterranean wrecks dated between 1550-
1100 BC, the evidence and data that we have
from the Late Bronze Age is more extensive,
making the picture more complex at the same
time. Two of these shipwrecks, The Cape
Gelidonya and the Uluburun (1200 and 1300
BC respectively), excavated off the south-west
Turkish coast by George Bass, are the first
planked vessels remains to have survived. The
planking of both ships was fastened together
by mortise and tenon joints, with the tenons
locked in position by treenails (McGrail, 2006,
pag. 60) (Plate 1). The Romans called to this
way of joinery Coagmenta punicana, which
means “the Phoenician joint”, and it may have
been transferred to the eastern Mediterranean
World from Egypt via the Levant The earliest
known use of this type of joints in the Levant
region is in a table from a middle of the second
millennium BC tomb at Jericho. (Casson, 1995
This fastening technique, certainly, is quite
similar to the one used in Egypt in the third
and early second millennium BC. The Egyptian
mortise and tenon joints, however, were not
locked. Therefore, it was used together with
other types of fastenings in order to give more
rigidity to the hull. One example of this is the
Cheops Ship (2600 BC). Her cedar planking
was fastened together by unlocked mortise
and tenon and, mainly, by two types of lashings:
between adjacent strakes and, transversally,
from sheer to sheer (McGrail, 2001, pag. 26-
54; 2006, pag. 58) (Plate 2). In 1850 BC the
boats found at Dashur also had unlocked
mortise and tenon joints, which were deeper
than those in Cheops, and some of the objects
found with them had locked ones. As Haldane
has suggested (1996) is more than probable
that this way of shipbuilding went on in Egypt
for millennia and it was not until when the
strong influence of the phoenicians was felt in
the Eastern Mediterranean that the Egyptians
began to build their vessels with locked mortise
and tenon. One example of this is the mid-first
millennium Egyptian boat found at Matariya,
which not only has locked mortise and tenon
plank fastenings but also contains frames
(McGrail, 2001, pag. 40).
The Phoenicians could have developed
therefore this technique of using locked mortise
and tenon fastenings (influenced by the
Egyptians), which gives to the hull more
structure integrity, around the Middle Bronze
Age. The wrecks of Cape Gelidonya and
Uluburun, according to the current evidence
available, were Levantine in origin (Bass, 1997,
pag. 269; Wachsmann, 1998, pag. 206-208).
Then, with the enrichment of their city-states
in the Levant coast and the consequent
development of their maritime trade among
the Eastern Mediterranean and beyond, this
technique was widespread and generally used
by the mid-first millennium BC.



During the fourth and third centuries BC Greek
culture and technology dominated the eastern
and central Mediterranean while Rome began
to gain force in the Italian Peninsula. From this
period we have a wreck site found off the shore
of Cyprus, near Kyrenia, that represents the
general nautical features that were to persist
for half a century or so in the Mediterranean:
Shell-first construction, planking fastened
together by locked mortise and tenon
fastenings and framing mostly fastened to the
planking by metal nails. The Kyrenia ship (300
BC) is quite similar in shape to the one found
in Ma´agan-Micheal (400 BC) off the Levant
coast but her hull is solely fastened by mortise
and tenon joints, without the help of any sewing
technique. The Ma´agan-Micheal wreck
presents sewing fastenings at the bow and
the stern what has been interpreted as to gain
further strengthening of the hull and to prevent
lateral opening of the strakes on the sides
(Kahanov, 2004, pag. 45).



The continuity of sewing techniques
During the mid-first millennium BC, however,
most of the archaeological evidence that we
have from wrecks, especially from the Central
and Western Mediterranean, suggest a rather
different picture. Several ships dated from the
sixth century BC right into Roman times, which
are either fully or partially sewn, have been
excavated in the last decades giving new light
and more complexity to the study of watercrafts
in the Mediterranean World. Ancient sources
as for example Homer (Iliad 2:135; Odyssey
5:234-257)), Virgil (Aeneid 6.413-414) or Pliny
(NH 24-65), suggest that Greek fleets had sewn
planking and that the use of sewn techniques
remained in Classical times (Casson, 1995,
pag. 43-68). The wrecks dated to this period
have been found off the Easter n Mediterranean
shores, as the mentioned Ma´agan-Michael
wreck; in Italy, as the ships of Giglio, Gela or
in the Venice Lagoon; France, as for example
the shipwreck Bon-Porté or Place Jules-Verne,
in Marseilles (Plate 3); and in Spain, as the
greek wreck of Cala Sant Vicenç, off the
northern coast of the Island of Mallorca (Nieto,
2002), or the seventh century BC Carthaginian
wreck of Playa de La Isla (Negueruela,.1995),
although this latter only has lashed framing
whereas her planking is fastened together by
mortise and tenon joints.


Sewing techniques were still
in use during Roman times
until the Medieval Period as
we can see in the wrecks of
Cavaliere (100 BC), Jeanne-
Garde B (Second century BC)
or in the Cap Bear C
shipwreck (First century BC).
In these times, when the
mortise and tenon technique
was the main way of plank
joinery and the influence of
frames within the hull
construction was growing,
sewing was used mostly for
repairs and in areas of the
vessel where leaks were most
likely to occur (underwater hull
and ends) (McGrail, 2001, pag.
138). Nevertheless, several
entire sewn-plank boats have
been excavated from coastal
sites in the Adriatic, in Croatia,
and in the delta of the River
Po despite the advances in
nautical technology (Plate 4).
Probably, these late sewn-
vessels are the answer of
indigenous societies to their
environment and to the
importance of their
economical position within the
Mediterranean community.
Normally they are found in
rivers, lakes, lagoons or deltas,
being very improbable their
use in long-distance voyages

At first, mortise and tenon
joints were used together with
sewn fastenings. With the
improvement of woodworking
in the Eastern Mediterranean
Sea, the technique of locked
mortise and tenon joints was
used as the only plank
fastening in the hull. Also, the
subsequent change to metal-
fastened frames instead of being lashed needed better skills
in the way the timber was elaborate. The development of these
techniques increased the cohesiveness of the planking shell,
both in strength and watertightness (McGrail, 2001, pag. 148).
These changes in the hull structure and in the shipbuilding
techniques from mid-second century until the Roman times
are directly related to the social and cultural transformations
that were going on in the Mediterranean World. The growth of
the cities-states in the Levant Coast and in The Aegean region
and the increase in the maritime trade competence led to the
necessity of more rigid vessels, with major capacity and better
manoeuvrability. This also led to a need of protection of the
trading goods and of the wealth of the cities-states. As McGrail
has pointed out, some of these changes would have been
stimulated by warship requirements. A ship built shell-first with
a fastening system of locked mortise and tenon would have
been “a better fighting machine than one with sewn-planking
and lashed framing” (2001, pag. 148).

Transition from Shell to Skeleton Construction




The Roman Age, from mid-second century BC
to the fourth century AD, was characterized in
nautical technology by a general continuity in
building techniques from the Hellenistic period
(Muckelroy, 1978, pag. 65-75; McGrail, 2001,
pag. 154; León & Domingo, 1992, pag. 199-
218). To this period belongs most of the
archaeological evidence that we have from
Mediterranean shipwrecks. And, certainly, the
increasing domination of Rome over the
Mediterranean World, defeating Greece and
Carthage at the end of the first millennium BC,
influenced in the quantity and quality of the
ships the were built at this time.
During this period, apart from small boats
which followed the same shipbuilding
techniques observed in the Kyrenia Wreck, the
increasing demand for cargo space can be
seen in the bigger tonnage of the merchant
ships. Examples of this are the first century
BC shipwrecks of La Madrague de Giens (400
tonnes) or Albenga (500-600 tonnes) (Parker,
1992). This resulted in the use of thicker
planking or in the construction of a hull with
inner and outer planking leaving some wool or
other fabric saturated in wax in between. This
would has given more strength to the hull
structure and integrity (Steffy, 1994, pag. 62-
65; León & Domingo, 1992, pag. 199-218),
being thus more capable or carrying bigger
and heavier cargoes. At the same time, planking
strength was increased, either in double-
planking ships or in single-planking ones, with
the use of more fastenings per unit length, as
we see in wrecks like La Madrague de Giens
or Antikythera I, in Greece (First century BC)
(McGrail, 2001, pag. 156). With these greater
hulls we also observe an increase in size of
the frames an in its use. They are internal and
discontinuous and begin to be fastened to the
keel giving more structural strength to the
vessel.

While the construction technique of shell-first
was still generally used in the Mediterranean
in shipbuilding, we begin to have some
evidence from the third and fourth century AD
of the new importance given to the frames in
determining the ship’s lines (Muckelroy, 1978,
pag. 64). At the end of this period there were
several changes in the social and economic
prevailing systems along the roman
Mediterranean that were reflected in the
technology used in shipbuilding (León &
Domingo, 1992, pag. 199-218). Certainly, there
was a tendency during the Roman Empire to
look for less costly and faster methods of
construction, giving less importance to the
durability of the vessel herself (Muckelroy,
1978, pag. 65; Casson, 1995, pag. 141-148;
McGrail, 2001, pag. 158). With the decline in
slavery at the en of the Roman Empire, the
expensiveness of shipbuilding process
increased making the ship-owners prefer
smaller and cheaper vessels. Wrecks of big
merchant ships are uncommon after the second
century AD. Furthermore, other social and
natural factors that could have influenced this
change in ship technology could have been
for example: new types of goods that were
traded, improvements in tools and techniques
used for construction, deforestation or the
introduction of fore-and-aft sail, what would
have reduced also considerably the use of
human force in the propulsion of the ships
(McGrail, 2001, pag. 158).

All these social and economic changes can
be implied in the study of a wreck found off
Turkish shores, The Yassi Ada 2, dated to the
fourth century AD, and of other ones from the
fifth century AD such as Fiumicino I or Dramont
5 and 6 (Parker, 1992). These ships were small
cargo vessels, built shell-first with planking
fastened by mortise and tenon joints and
frames alternately floors and half-frames. The
major importance given to the frames can be
seen in the bigger distance that can be
appreciated between the joints and their smaller
size. Finally, we find mortises and tenon joints
not locked whose mere purpose was to help
the plank alignment, as it was when they first
appeared in Egypt.

The frame-first construction technique was
known by the Greeks in the fifth century BC,
as we can infer from Herodotus (1.194) but
only in relation to the building of skin boats
(Basch, 1972, pag. 47). It is, however, in the
seventh century AD when we find the first
archaeological evidence for ships built frame-
first. Wrecks as St. Gervais 2, Tantura I or
Pantano Longarini had their planking treenailed
and nailed to a pre-erected framing instead of
being fastened together (McGrail, 2001, pag.
161). Other wrecks, as Yassi Ada I (c. AD 625),
were plank-first built in their lower hull, while
frame-first in the upper part where there were
simpler shapes. By 1025 AD, the technique of
fastening planks by locked mortise and tenon
joints was abandoned almost completely. The
best evidence that we count with from this
period is the Serçe Limano wreck, entirely built
frame-first (Steffy, 1994, pag. 85-91) (Plate 6).
The consequences of frame-first construction
can be followed during the next centuries, with
the disintegration of the Roman Empire and
the development of the Medieval Europe. The
technological changes that have happened
during the first centuries AD were influenced
by the new social and economic systems that
were being shaped at that moment. Now, the
new shipbuilding method of frame-first
construction, consequence of the continuous
social interaction with the technology, was
going to play an important role in the history
of the incoming centuries. Frame-first
construction made possible to build bigger
ships in a quicker way. The resulting vessels
had more seaworthy hulls appropriate for the
ocean crossings that later on were going to
take place (McGrail, 2001, pag. 160; Muckelroy,
1978, pag. 65; León & Domingo, 1992, pag.
199-218).
