MAN 11G90ME-GI ENGINE TESTED WITH 100% LNG FUEL

Tuesday, January 28, 2020 

According to MAN Energy Solutions, its Korean licensee HHI-EMD (Hyundai Engine Machinery Division) has completed the first shop test for the first of six ME-GI engines bound for a series of container ships for Singapore-based, Eastern Pacific Shipping, with the engine running successfully at 100% load in gas mode during the tests.

The six units are MAN B&W 11G90ME-GI dual-fuel configurations operating on LNG with delivery dates scheduled between 2020-2022. Hyundai Samho Heavy Industries (HSHI) will construct each of the neo-Panamax boxships.

Capt Anil Singh, COO Eastern Pacific Shipping, said: “EPS is proud to be working alongside MAN by installing their ME-GI engines in our LNG dual-fuel ultra-large containerships. Instead of taking a wait-and-see approach towards decarbonisation and environmental protection, EPS decided to use LNG as a marine fuel and chose to install the two-stroke ME-GI engine in these newbuilds. When powered by LNG, the ME-GI will reduce these vessels’ carbon footprint by significantly lowering CO2, NOx, and SOx emissions. The success of the shop test reinforces our decision, and we look forward to the addition of this environmentally-friendly tonnage to our diverse fleet.”

The shop test also marked the debut of of MAN Energy Solutions’ new Pilot Booster Injection Valve (PBIV), which employs smaller or larger atomising holes, depending on fuel mode, to inject fuel into engines. As such, in gas mode, the use of smaller holes significantly reduces pilot-oil consumption to just 1.5%, approximately half of what was previously required; diesel mode employs the larger-sized holes.

The PBIV valves represent MAN Energy Solutions’ latest pilot-injection technology, which caters for dual-fuel running by optimising SPOC (Specific Pilot Oil Consumption).

Bjarne Foldager, SVP Head of Two-Stroke Business, MAN Energy Solutions, said: “This shop test is notable for a number of reasons. Again, the ME-GI has shown what mature technology it is, running stably at 100% load in gas mode, while the introduction of our PBIV technology drastically cuts pilot-oil consumption by half compared to previous. The test also showed that the ME-GI capably handles load changes and maintains an impeccable cylinder condition. As such, the ME-GI has set the bar even higher for dual-fuel propulsion and is the de facto industry standard.”

MAN Energy Solutions reports that it has over 200 ME-GI units on its order books or already in service, with references in every major marine segment, while the ME-GI design has logged over 750,000 dual-fuel operating hours in establishing itself as well-proven technology. The ME-GI claims to offer seamless switching between fuels and elimination of methane slip.

The company states that it has confirmed 250+ sales within its portfolio of low-speed, dual-fuel engines – all running on LNG or other, clean fuels such as LPG and methanol – which it says is testament to its leadership within this critical market segment.
