From the Energy Information Administration:
The General Dynamics shipyard in San Diego delivered the world’s first liquefied natural gas (LNG) powered containership to TOTE Maritime on October 16. The 764-foot long Isla Bella is the first of the Marlin class, a new class of container ship built in the United States, making it Jones Act-qualified for shipments between U.S. ports. The ship was built by the National Steel and Shipbuilding Company, a division of General Dynamics.

Delivered nearly two months ahead of schedule, the Isla Bella will operate out of Jacksonville, Florida, providing service to and from San Juan, Puerto Rico. The second ship of the class, the Perla del Caribe, will be delivered in early 2016 and will service the same trade route. These ships join a small group of LNG-powered ships, which currently number fewer than 100, excluding LNG tankers, according to data from DNV GL Maritime. They are the first in the largest category of vessels–container ships, numbering in the tens-of-thousands–to be built with dual-fuel propulsion intent on employing LNG as the primary fuel.
