German marine engine producer MAN Energy Solutions on Wednesday (12 August) said its successful ME-GI (Gas Injection) engine has passed its sea trials and set a new industrial standard for two-stroke propulsion engines aboard LNG carriers, container vessels, car carriers and bulk carriers.
The ME-GI engine provides ship-owners and operators with a solution within environmentally friendly and high-efficiency, two-stroke technology, without the greenhouse emissions such as methane slip that are characteristic of competing engines.
With the ME-GI engine, two-stroke development has taken a step further by combining the unique properties of multi-fuel combustion and the well-known reliability of MAN Energy Solutions ME-engine, it said.
The first ME-GI engine featuring its newly-developed Pump Vaporizer Unit (PVU) has successfully completed LNG gas trials in Korea, said the company.
The engine is the first in a series of six neo-Panamax boxships – built by HSHI (Hyundai Samho Heavy Industries), and ordered by Eastern Pacific Shipping (EPS), the Singapore-based shipping company – with each powered by individual MAN B&W 11G90ME-GI main engines.
CMA CGM has already chartered the vessel, named Tenere, from EPS.
MAN Energy Solutions added that it 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 and liquefied petroleum gas (LPG).
“The successful gas and sea trials and the on-schedule delivery of CMA CGM Tenere make for an important MAN and EPS milestone,” said Cyril Ducau, EPS CEO.
“Three years ago, we committed to investing in alternative marine fuels, like LNG, to lead the industry towards decarbonisation and environmental preservation.
“This commitment included selecting MAN’s high-pressure ME-GI engines, which are highly efficient and, importantly, reduce methane slippage to negligible levels.
“These vessels will be IMO 2030 compliant years ahead of schedule and will be the cleanest vessels of their category on-the-water today.”
“The ME-GI engine is mature technology that has accumulated multiple references in multiple segments and is further improved by the introduction of the PVU, which ensures an optimal integration between the engine and supply system,” added Bjarne Foldager – Senior Vice President and Head of Two-Stroke Business at MAN Energy Solutions.
