2015 was a remarkable year for General Dynamics NASSCO: of the three lead ships it delivered in 2015, two were designed for propulsion with liquefied natural gas (LNG) – the Isla Bella and the Lone Star State – representing new and separate ship classes. NASSCO says this groundbreaking green ship technology will dramatically decrease emissions and increase fuel efficiency when compared to conventionally-powered ships.
In October, NASSCO delivered the world’s first liquefied natural gas (LNG) powered containership, the Isla Bella, to TOTE nearly two months ahead of schedule. As part of a two-ship contract signed in December 2012 with TOTE, the 764-foot long Marlin Class containerships are the largest dry cargo ships powered by LNG, making them the cleanest cargo-carrying ships anywhere in the world. Newly developed and ground-breaking technology used in the design and build of the containerships dramatically decrease emissions and increase fuel efficiency when compared to conventionally-powered ships – or the equivalent of removing nearly 16,000 automobiles from the road. The Isla Bella’s sister ship, the Perla Del Caribe, is currently under its final stages of construction at the NASSCO shipyard and is scheduled to be delivered to TOTE during the first quarter of 2016.
Most recently, NASSCO delivered the first ECO Class tanker, the Lone Star State, to American Petroleum Tankers (APT). The new ECO Class tanker 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 tankers with a 330,000 barrel cargo capacity. The 610-foot-long tankers were built with a new “ECO” design, offering significantly improved fuel efficiency and the latest environmental protection features. The tankers are 33 percent more fuel-efficient than the previous five tankers built by NASSCO for APT between 2007 and 2010.
For its commercial work, NASSCO partners with South Korean shipbuilding power, Daewoo Shipbuilding & Marine Engineering (DSME), for access to state-of-the-art ship design and shipbuilding technologies.
First LNG Bunkering for Perla Del Caribe
On December 11, General Dynamics NASSCO successfully completed bunkering of liquefied natural gas (LNG) for the Perla Del Caribe. Bunkering services were provided by the California-based company Clean Energy as well as Baker Hughes and Envent during a 48-hour period at the NASSCO shipyard in San Diego.
The vessel received 210,000 gallons of LNG which is nearly double the amount bunkered for its sister ship, the Isla Bella.
Powered by LNG, this groundbreaking green ship technology will dramatically decrease emissions and increase fuel efficiency when compared to conventionally-powered ships – which is equivalent to removing nearly 16,000 motor vehicles off the road. NASSCO states the 764-foot long containerships will be the longest dry cargo ships powered by LNG – making them the cleanest cargo-carrying ships anywhere in the world.
