Crowley reaches milestone with setting of LNG engine in new ship
Crowley Maritime Corporation reached another critical milestone with the recent setting of the main engine onto El Coquí, the first of two new, Commitment Class ConRo (combination container and Roll/On-Roll/Off) ships that will be powered by liquefied natural gas for use in in the ocean cargo trade between Jacksonville and Puerto Rico, the company said in its press release.
The engine was placed using a series of heavy lifts by 500-ton cranes in the shipyard of VT Halter Marine, a subsidiary of VT Systems, Inc., where El Coquí (ko-kee) and sister ship, Taíno (tahy-noh), are under construction. The engine has a total weight of 759 metric tons and measures 41 feet high, 41 feet in length, and 14.7 feet wide.
Liquefied natural gas (LNG) is a stable gas that is neither toxic nor corrosive and is lighter than air. It is the cleanest fossil fuel available, netting a 100-percent reduction in sulphur oxide (SOx) and particulate matter (PM), and a 92-percent reduction in nitrogen oxide (NOx). LNG also has the ability to significantly reduce carbon dioxide (CO2), a contributor to greenhouse gas emissions, as compared with conventional fossil fuels.
Designing, building and operating LNG-powered vessels is very much in line with Crowley’s overall EcoStewardship© positioning and growth strategy. The company formed an LNG services group in 2015 to bring together the company’s extensive resources to provide LNG vessel design and construction management; transportation; product sales and distribution, and full-scale, project management solutions.
These Commitment Class, Jones Act ships are designed to travel at speeds up to 22 knots while maximizing the carriage of 53-foot, 102-inch-wide containers. Cargo capacity will be approximately 2,400 TEUs (20-foot-equivalent-units), with additional space for nearly 400 vehicles in an enclosed Ro/Ro garage.
The Jones Act is a federal statute that provides for the promotion and maintenance of a strong American merchant marine. It requires that all goods transported by water between U.S. ports be carried on U.S.-flag ships constructed in the United States, owned by U.S. citizens, and crewed by U.S. citizens and U.S. permanent residents.
Crowley has served the Puerto Rico market since 1954, longer than any other carrier in the trade, and occupied the 75-acre Isla Grande Terminal the entire time, making it the longest continual occupant of any Jones Act carrier in the trade. The company, with over 250 Puerto Rico employees, is also the No. 1 ocean carrier between the island commonwealth and the U.S. mainland with more weekly sailings and more cargo carried annually than any other shipping line.
