NASSCO Delivers Environmentally Friendly Tankers
NASSCO has delivered four Alaska class oil tankers with the first being the Alaskan Frontier completed on August 2004 and the last Alaskan Legend completed on August 14, 2006. Along with their other two sister ships, the Alaskan Explorer and Alaskan Navigator]], they can hold 1.3 million barrels of crude oil individually. These amazing ships that NASSCO produce, earned there the title of being the most environmental friendly tankers in the world for many reasons. The Alaska-Class takers have a double hull construction that has been designed for a life of 35 years and their deck structure has a life of 50 years. The Alaska-Class ships use state of the art technologies, such as diesel-electric propulsion system, with redundant engines, shafts and screws. They also have all of their cargo transferring pipes inside the hull rather on its decks to reduce the chance of accidental spills. The Alaska-Class ships also use sea-water shaft seas instead of oil, to minimize any chances of oil leaking in to the waters it sails.

“Talk is a pure art. Its only limits are the patience of listeners who, when they get tired, can always pay for their coffee or change it with a friendly waiter and walk out.”
