What is Oil tanker?
[[File:Supertanker AbQaiq.jpg|thumb|300px|The commercial oil tanker AbQaiq]] An '''oil tanker''', also known as a '''petroleum tanker''', is a [[ship]] made for the bulk transport of [[oil]]. There are two basic types of oil tankers: the '''crude tanker''' and the '''product tanker'''. Crude tankers move large quantities of unrefined [[crude oil]] from its point of extraction to refineries. Product tankers, generally much smaller, are designed to move [[petrochemicals]] from refineries to points near consuming markets. == Bibliography == * {{cite book | author = Central Intelligence Agency | author-link = Central Intelligence Agency | title = CIA World Factbook 2008 | url = https://www.cia.gov/library/publications/the-world-factbook/index.html | access-date = 2008-02-22 | year = 2007 | publisher = Skyhorse Publishing | isbn = 978-1602390805 | archive-date = 2008-08-12 | archive-url = https://web.archive.org/web/20080812233855/https://www.cia.gov/library/publications/the-world-factbook/index.html | url-status = dead }} *{{cite web |url=https://exchange.dnv.com/exchange/main.aspx?extool=vessel&subview=summary&vesselid=16864 |title=Knock Nevis |access-date=2008-04-08 |author=Det Norske Veritas |author-link=Det Norske Veritas |year=2008 |work=DNV Exchange |publisher=Det Norske Veritas }} *{{cite book |first=Jack |last=Devanney |title=The Tankship Tromedy: The Impending Disasters in Tankers |publisher=The CTX Press |url=http://www.c4tx.org/ctx/pub/tromedy2.pdf |location=Tavernier, FL |year=2006 |isbn=0-9776479-0-0 }} *{{cite journal | last = Douet | first = M | date = July 1999 | title = Combined Ships: An Empirical Investigation About Versatility | journal = Maritime Policy and Management | volume = 26 | issue = 3 | pages = 231–248 | publisher = Taylor and Francis, Ltd. | doi = 10.1080/030888399286862 | url = http://ntlsearch.bts.gov/tris/record/tris/00767781.html | access-date = 2008-04-07 | archive-date = 2008-06-11 | archive-url = https://web.archive.org/web/20080611191123/http://ntlsearch.bts.gov/t
