Shop test for first DF 11G90ME-GI engine
The six units, bound for a series of Eastern Pacific Shipping container ships, 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, chief operating officer at 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 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).
