NASSCO Delivers American Petroleum Tanker

By Mark Edward Nero

On Dec. 4, San Diego-based General Dynamics NASSCO delivered the company’s first “ECO Class” tanker, the Lone Star State, to American Petroleum Tankers.

The vessel is the first of a five-tanker contract between NASSCO and American Petroleum, which calls for the design and construction of five 50,000 deadweight-ton, LNG-conversion-ready product tankers with a 330,000 barrel cargo capacity.

The ships were designed by DSEC, a subsidiary of Daewoo Shipbuilding & Marine Engineering of South Korea. The design incorporates fuel efficiency concepts through several features, including a G-series MAN Diesel & Turbo ME slow-speed main engine and an optimized hull form.

The tankers will also have the ability to accommodate future installation of an LNG fuel-gas system.
The 610-foot-long tankers are a new design offering improved fuel efficiency and the latest environmental protection features including a ballast water treatment system.

“The delivery of this new vessel symbolizes the future of American shipping: innovative, cost-effective, and green, General Dynamics NASSCO President Fred Harris said. “The Lone Star State, along with the four others we are currently building for APT, will be among the most fuel-efficient and environmentally-friendly tankers – anywhere in the world.”

The tankers, Harris said, are 33 percent more fuel-efficient than five previous tankers built by NASSCO for American Petroleum between 2007-2010.

Since the cut of the first piece of steel, local dignitaries have been involved in the build process of the tanker.

In September 2014, San Diego Mayor Kevin Faulconer signaled the start of construction, citing it as “a great example of innovative technology” and a “symbol of jobs and opportunity.” In March 2015, Faulconer’s wife Katherine laid the keel. Two months ago, NASSCO shipbuilders christened the vessel.

The construction and operation of the five new tankers are aligned with the Jones Act, which requires that ships carrying cargo between US ports be built in US shipyards.
