Matson Navigation Company has ordered two 3600 teu container ships that will be powered by two MAN B&W 7S90ME-GI dual-fuel engines.
The new container ships will be constructed by Aker Philadelphia Shipyard in the U.S. and are scheduled for delivery in the third and fourth quarters of 2018. The deal includes an option for three further vessels.
Largest Duel-Fuel Engines
The engines are the largest dual-fuel engines ever ordered in terms of power output with each engine developing 42,700 kW. MAN Diesel Turbo’s licensee, Hyundai, will manufacture the engines that will be able to use HFO, MDO or LNG as fuel.
Diesel Operating Principle
MAN Diesel & Turbo reports that the 7S90ME-GI uses the Diesel cycle to maintain high efficiency, with no need for any derating. By virtue of its diesel operating principle, it will have negligible methane slip and no need for restrictive load ramps or other knock-preventing measures.
Green Ship Technology
Matson reports that the 850-foot long vessels will be the largest Jones Act containerships ever constructed and are designed to operate at speeds in excess of 23 knots. The vessels will incorporate a number of “green ship technology” features such as a fuel-efficient hull design, dual-fuel engines, environmentally safe double-hull fuel tanks and freshwater ballast systems.
