  Welcome to Maritime Replicas
With the main oil producers concentrated in the Middle East and the main consumers being concentrated in the West, the overall size of tankers was generally limited by the maximum that could use the Suez Canal.
Tankers were built with longitudinal, as well as transverse, bulkheads, to provide a large number of separate tanks for the oil -a precaution to minimize the escape of oil in the case of the vessel being holed.
The biggest growth in size was in the oil tankers due very largely to extraneous reasons.

 GMA: How Big is an Oil Tanker?
To carry a large amount of oil, tankers are designed to be quite large.
The Exxon Valdez was considered a midsized oil tanker measuring 967 feet long and 166 feet wide.
By measuring an average size oil tanker, such as the Exxon Valdez, students will have a much better understanding of how large a typical oil tanker is. In addition, the students will be asked to sketch a scale drawing of a typical oil tanker.

Tankers are enormously strong vessels, built with a honeycomb construction, a modern crude carrier typically having fifteen cargo tanks protected by a double hull structure around the sides and bottom, in which sea water ballast can be carried for the empty voyage after the oil cargo has been delivered.
Specialist tankers include vessels which are configured to carry as many as fifty different grades of chemicals and oils, each with their own separate pumping systems and capable of coping with cargoes that need to shipped hot, cold or under a blanket of nitrogen.
Tankers have had a bad press, and are associated with oil pollution, but the facts are very different, with pollution steadily reducing year on year, despite the steady increase in the quantity of oil carried by sea.

 Oil Pollution
Although tanker accidents are comparatively rare and result in only a small fraction of the total amount of oil entering the sea each year, some accidents have caused very serious local pollution and have had a major impact on the development of environmental legislation.
Tankers of 5,000 dwt and above must be fitted with double bottoms and wing tanks extending the full depth of the ship's side.  The regulation allows mid-deck height tankers with double-sided hulls, such as those developed by Japanese and European shipbuilders, as an alternative to double hull construction.
Oil tankers of 600 dwt and above but less than 5,000 dwt, must be fitted with double bottom tanks and the capacity of each cargo tank is limited to 700 cubic metres, unless they are fitted with double hulls.

Predominantly, an oil spill is related to the spills caused due to accidents involving tankers, causing a serious impact on coastal activities and on those who exploit the resources of the sea.
Oil spills, whether or not they are petroleum-based, pose an immediate threat to the environment and require quick and thorough responses.

 Oil tankers
Although mineral oil was first used primarily for lighting, the invention of the Diesel and later, the internal combustion engine soon increased its demand enormously.
The world’s first true oil tanker is generally accepted to have been the Gluckauf, built in 1886 to carry oil in bulk oil to Europe.
Further increases followed, and the result was a collapse in demand for oil and for the tankers needed to transport it.

 Oil Pollution
Measures introduced by IMO have helped ensure that the majority of oil tankers are safely built and operated and are constructed to reduce the amount of oil spilled in the event of an accident.
The potential for oil to pollute the marine environment was recognised by the International Convention for the Prevention of Pollution of the Sea by Oil, 1954 (OILPOL 1954).
The water at the bottom of the tank is pumped overboard and at the terminal oil is pumped on to the oil left in the tank.

 Threats to Oil Transport
Tankers are too slow and cumbersome to maneuver away from attackers; they don't have any protection and they have nowhere to hide.
They are so narrow that a single burning supertanker and its spreading oil slick could block the route for other tankers, hence rocking the entire global oil market for several weeks at the very least.
For a typical supertanker carrying about two million barrels of oil, the rate rose to $450,000 a trip from $150,000, adding about 15 cents a barrel to the delivered cost of the oil -- and that is just for the ship; the cargo is insured separately.

 GGL - Oil Tankers
Oil is contained directly within the hull itself with only a few millimeters of metal between it and the ocean.
If a hull breach were to occur in a tanker based on this improved design, the inner hull and the cells holding the oil would stand far more chance of remaining intact.
The GGL proposes that all new oil tanker constructions are designed to a global standard using safer inner cell structures and that high spill risk tankers be scrapped immediately.

 Revised phase-out schedule for single-hull tankers enters into force
It specifies that tankers of single hull construction should be phased out or converted to a "double hull" according to a schedule based on their year of delivery.
The double hull requirements for oil tankers are principally designed to reduce the risk of oil spills from tankers involved in low energy collisions or groundings.
Category 2 oil tankers, which have some level of protection from protectively located segregated ballast tank requirements will be phased out according to their age up to 2010.

 Security of oil tankers fuels worry | EnergyBulletin.net | Peak Oil News Clearinghouse
LONDON - Now that OPEC has agreed to raise its crude oil production quotas in hopes of taming high and jittery oil prices, industry experts are growing more concerned about both the capacity and the security of oil tankers, the next link in the supply chain.
The world's tanker fleet is already stretched thin by robust demand for oil, by looming deadlines for the phase-out of single-hull tankers for safety and environmental reasons, and by lengthening backlogs at the shipyards where new tankers are built.
Tankers and tanker-loading facilities have already been the targets of attacks by al-Qaida and other anti-Western groups, threatening to disrupt oil supplies and adding to the upward pressure on prices, maritime insurance premiums and tanker charter rates.

Fleet operators have been actively scrapping older single-hull ships as new double-hulls become available, but even so, about a third of large-scale oil deliveries worldwide this year will still be made by single-hulled vessels, and the looming shortage of tanker capacity may lead operators to extend their service lives.

 Global Marine Oil Pollution Information Gateway • Facts • Oil spills (accidental discharges)
Discharges of oil from shipping, offshore extraction of oil, and transport of oil in pipelines is the result of either accidents or "normal", deliberate operational discharges.
According to estimates made of the contribution of oil to the sea from different sources (NRC), accidents involving oil tankers and offshore installations account for some 10 per cent of the annual total amount of oils entering the marine environment.
The percentages of oil spilled from different sources vary greatly from year to year; in some years, tanker accidents represent the largest single source of spilled oil, but only in a very few years is it the case that most of the oil spilled (in significant spills) during that year came from tankers.

To supply all of the world's crude oil needs today, there are only about 3,500 tankers steaming out on the open seas or anchored at ports.
Demand for their services far exceeds this supply, and as a result, tanker rates have soared in the past year much faster than the price of crude oil itself.
Rates on the big bruisers that haul 2 million barrels of oil from the Persian Gulf to Japan hit as much as $250,000 per day last fall and are not too far off that pace today.

 Oil Tankers Slow to Shift to Anti-Spill Double Hulls
On a recent morning, the tanker Polar Endeavour is anchored behind a spit in calm waters off Port Angeles, waiting to offload some of its 37 million gallons of crude to a Ferndale refinery.
In December, a fully loaded tanker leaving the Gulf of Alaska accidentally dropped its anchor — which typically weighs up to nine tons — while the ship was in motion.
Building new tankers takes years and costs hundreds of millions of dollars, and federal law requires that ships operating between U.S. ports be made in the United States, where labor costs are higher.
