General Dynamics NASSCO Delivers Final ECO Class Tanker


General Dynamics NASSCO delivered the Liberty, the third and final ship to be constructed for SEA-Vista as part of a larger eight-ship ECO Class tanker program.

In 2013, NASSCO entered into an agreement with SEA-Vista to design and build three 50,000 deadweight-ton, LNG-conversion-ready product carriers. The 610-foot tankers are a new “ECO” design, offering improved fuel efficiency and cleaner shipping options. Construction for the first of the three ships for SEA-Vista began in November 2014. The first two ships—the Independence and the Constitution—have been delivered and are servicing the Jones Act trade.

The Liberty is the seventh vessel in an eight-ship ECO Class tanker program for two separate customers, SEA-Vista LLC and American Petroleum Tankers. The eighth ship of the program, the Palmetto State, is scheduled to be christened and launched on March 25, 2017, at the NASSCO shipyard in San Diego.
