VT Halter Marine has set the main engine onto the first of two LNG-powered combination container and Roll/On-Roll/Off cargo ships being built for Crowley Maritime for use in the Jones Act trade.
Crowley says the setting of the engine marks a critical milestone in the construction of the Commitment-class vessels, named El Coquí (pronounced ko-kee) Each of the ships will be equipped with a single low-speed, dual-fueled MAN Turbo & Diesel ME-GI Main Engine, capable of operating interchangeably on LNG or marine diesel fuel.
The engine was placed on the into the El Coquí using a series of heavy lifts by 500-ton cranes in the shipyard of VT Halter Marine in Pascagoula, Mississippi, where the two vessels 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.
The ships are designed to travel at speeds up to 22 knots and carry containers ranging in size from 20-foot standard to 53-foot-long, 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.
El Coquí and are due for delivery in the second and fourth quarter 2017, respectively.
