Though there are more than 3,600 tankers in service in the world, about one-third of the world's oil supply is transported by just 435 of them, the towering two-million-barrel tankers known prosaically in the industry as very large crude carriers, or VLCCs.
.
These ships are almost always completely booked, and new ones are slow to reach the market. The shipyards that can build them all have deep backlogs of orders for tankers and other vessels, so a new VLCC ordered today would probably not be delivered until late 2007 or early 2008 at the earliest.
.
Tankers of the next largest size, known as Suez Max tankers because they barely fit through the Suez Canal, are also booked close to capacity.
.

.
Shippers may be forced to use smaller ships or keep older single-hull tankers in service longer than planned. After the Exxon Valdez disaster in Alaska in 1989 and several major spills in European waters in the 1990s, the European Union and the United States adopted rules calling for tankers with single-walled hulls to be phased out in favor of a double-walled hull with about six feet of space in between, making the oil storage tanks much less likely to be punctured in an accident.
.
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.

Tehét jelenleg 3600 olajtanker van,ebböl az igazán lényegesek a 2 millió tonnásak,melyekböl 435 darab van.
Jelenleg a tankerek harmada nem duplafalú,ami annyit tesz hogy pár vállalkozókedvű ürge simán lukat tud robbantani bele.
Vajon mi történik a világpiacon,ha valaki elkezdi a szupertankereket ritkítani?Az ami olajbehozatal napi 50 darab szupertankert feltételez.Ha nem érkezik meg ennyi,vagy néhány kiesik,akkor gondok lesznek...(pláne hogy ezek hosszú ídkre be vannak táblázva)
