General Dynamics NASSCO has christened the first ECO tanker for American Petroleum Tankers (APT), under construction at the company’s shipyard in San Diego. The ECO tanker, the Lone Star State, is the first of a five-tanker contract between NASSCO and APT, which calls for the design and construction of five 50,000 deadweight ton, LNG-conversion-ready product carriers with a 330,000 barrel cargo capacity.
The 610-foot-long tankers are a new “ECO” design, offering improved fuel efficiency and the latest environmental protection features including a Ballast Water Treatment System.
“Incorporating new and innovative green ship technology, these tankers are the future of American petroleum shipping. When delivered they will be among the most fuel-efficient and environmentally-friendly tankers anywhere in the world,” said Kevin Graney, general manager and vice president for General Dynamics NASSCO.
In September 2014, San Diego Mayor Kevin Faulconer signaled the start of construction of the ECO tanker. In March 2015, San Diego’s First Lady and wife of Mayor Faulconer, Mrs. Katherine Faulconer, laid the keel.
The ships were designed by DSEC, a subsidiary of Daewoo Shipbuilding & Marine Engineering (DSME) of Busan, South Korea. The design incorporates improved fuel efficiency concepts through several features, including a G-series MAN ME slow-speed main engine and an optimized hull form. The tankers will also have dual-fuel-capable auxiliary engines and the ability to accommodate future installation of an LNG fuel-gas system.
A day earlier, on Friday, October 16, NASSCO shipbuilders began construction on a fifth tanker for APT.
The construction and operation of the new tankers are aligned with the Jones Act, which requires that ships carrying cargo between U.S. ports be built in U.S. shipyards.
