Over the next two decades, Iran would also need 500 new ships, including 120 oil tankers, 40 liquefied natural gas (LNG) carriers and over 300 commercial vessels. In 2009, in a move aimed at further enhancing Iran's shipbuilding industry, President Mahmoud Ahmadinejad said he will ban the purchase of foreign ships by Iranian organizations. Moreover, various kinds of industrial lubricants have been produced by Pars Oil Company as well as Behran Oil Company and, at present, about 70% of the lubricant needed by the fleet is supplied domestically.
