Marking another success for MAN Energy Solutions in the Chinese market, Yangzijiang Shipbuilding Group has ordered 10 MAN B&W 7G80ME-C10.5-GI engines in connection with the construction of 10 LNG-fueled containerships for Seaspan Corporation. The 7,000 TEU vessels will be largest ME-GI-powered container vessels ever built by a Chinese shipyard.
The contract includes an option for five further vessels. Engine delivery is scheduled from October 2023 to 2024.
According to Thomas Hansen, head of promotion and customer support, MAN Energy Solutions, the continuing success of the ME-GI engine is primarily due to the ever-increasing focus on methane-slip reduction and fuel efficiency.
“This latest mark of the engine,” he said, “comes with a gas-optimized tuning that significantly improves fuel efficiency when operating on gas, while simultaneously maintaining an industry-leading, low methane-slip of just 0.20-0.28 g/kWh over its entire load range.”
Over the course of the past year, MAN Energy Solutions reports that it has received multiple orders from Chinese shipyards for ME-GI engines for a broad variety of projects including pure car-truck carriers (PCTCs), bulk carriers, and oil tankers.
“The Chinese market has great potential for us and we plan to increase the more than 1.8 million running-hours that the ME-GI has accrued to date running on LNG alone,” said Hansen.
NEW INDUSTRIAL STANDARD
MAN Energy Solutions says the ME-GI (-Gas Injection) engine has set a new industrial standard for two-stroke propulsion engines providing ship-owners and operators with “a peerless solution within environmentally friendly and high-efficiency, two-stroke technology, without the greenhouse emissions such as methane slip that are characteristic of competing engines.”
“The Diesel principle not only provides the ME-GI engine with high operational stability and efficiency, but also ensures 100% reliable operation during load changes on gas with just normal additions of pilot-oil amounts,” says the company. “Furthermore, the ME-GI operational principles features a seamless change-over between gas operation and diesel operation. The ME-GI engine is the most environmentally friendly, technology available within the two-stroke engine segment.”
MAN Energy Solutions has also developed an ME-LGI (-Liquid Gas Injection) dual-fuel engine that expands the company’s dual-fuel portfolio, enabling the use of more sustainable fuels such as methanol.
