MAN’s ME-GI engine gives shipowners and operators the option of utilising fuel or gas

The Factory Acceptance Test (FAT) of the first ME-GI engine in Japan recently took place at the Tamano Works of Mitsui Engineering & Shipbuilding Co., Ltd. (MES).

Overseen by the DNV GL classification society, the MAN engine is the first of two 8S70ME-C8.2-GI units for delivery to VT Halter Marine of Mississippi, USA for installation aboard two 2,400 teu ConRo ships for Crowley Maritime Corporation, USA.

Crowley ordered the ME-GI engines, along with three MAN 9L28/32DF auxiliary engines for each vessel, back in early 2014.

When completed the ConRo ships – with container Lift-On/Lift-Off (LO/LO) and Roll-On/Roll-Off (RO/RO) – will be named El Coquí and Taíno. They are scheduled for delivery in the second and fourth quarters of 2017, respectively.

The vessels will be two of the world’s first LNG-powered ConRo ships, designed to travel at speeds up to 22 knots and carry various sized containers, along with hundreds of vehicles in enclosed, weather-tight car decking.

Crowley said that the newbuildings will reduce the amount of CO2 emissions attributable to each container by approximately 38%. Additionally, the ships will meet or exceed all regulatory requirements and have the CLEAN notation, which requires limitation of operational emissions and discharges, as well as the Green Passport, both issued by DNV GL.

MAN’s ME-GI engine gives shipowners and operators the option of utilising fuel or gas depending on relative price and availability, as well as environmental considerations.

It uses high-pressure gas injection that is not affected by the multiple de-ratings, fuel-quality adjustments or large methane-slip issues as have been seen with other, dual-fuel solutions.

An ME-LGI counterpart that uses LPG, methanol and other liquid gasses is also available, and has already been ordered.
