Crowley Maritime Corporation, a U.S.-owned and operated marine solutions, transportation and logistics company providing services in domestic and international markets, has announced that it has signed a contract with VT Halter Marine Inc., of Pascagoula, Mississippi, to build two of the world’s first LNG-powered ConRo ships (hybrids of container and roll on-roll off vessels). 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 high-capacity units, along with hundreds of vehicles in enclosed, weather-tight car decking. The new double-hulled ConRo ships have been designed to maximize the carriage, which offer the most cubic cargo capacity in the trade. The ships will be 720 feet long, 106 feet wide (beam), have a deep draft of 33 feet meters, and an approximate deadweight capacity of 26,500 metric tons. Cargo capacity will be approximately 2,400 TEUs (20-foot-equivalent-units), with additional space for nearly 400 vehicles. The Commitment Class, Jones Act ships, scheduled for delivery in second and fourth quarter 2017, will replace Crowley’s towed triple-deck barge fleet, which they have used since the early 1970s.
