G50ME-C9 Engine Successfully Passes TAT

MAN Diesel Turbo’s G50 engine has successfully upheld a Type Approval Test during Mitsui in Japan. Upon entering service, a engine will energy a world’s initial ethane-fuelled eco-friendly LEG (Liquefied Ethane Gas) conduit – a initial of 3 such vessels to be built in China by SinoPacific Shipyard for a German shipowner, Hartmann Reederei.

Besides handling on ethane, a stretchable ME-GI engine will be means to work on HFO, MDO and gas oil. Propulsion potency will be serve softened by contracting an MAN Kappel propeller with rudder-bulb system.

The G50-type has been grown with an eye on shortening prolongation costs and accordingly facilities a reduce weight and shorter length than a predecessor, while still being means to exaggerate a same energy output.

The DNV-GL sequence multitude oversaw record in Japan where a engine was tested as an ME-C form regulating on MGO though a gas complement also successfully finished a vigour and duty test. The initial exam and operation on ethane gas will take place after loading in Texas aboard a 36,000 m3 LEG conduit once ethane gas has been bunkered, after that a engine will strictly be named a 7G50ME-GIE (Gas Injection Ethane) type.

The news of a successful TAT follows a proclamation by a JACCAR/Hartmann Reederei corner try that has systematic another 5 × 85,000 m3 ‘Eco Star 85K’ Very Large Ethane Carriers (VLECs) with any vessel to be powered by a singular MAN BW 6G60ME-GIE categorical engine. In further these latest 5 vessels will be IMO Tier III NOx agreeable by a use of MDT’s exclusive EGR, Exhaust Gas Recirculation System.

This latest sequence brings a sum of ethane-burning ME-GIE engines on sequence with MAN Diesel Turbo to 8 with, a association reports, some-more in a pipeline.

About a ME-GI engine

The ME-GI Dual Fuel Low Speed Diesel Engine represents a perfection of many years’ of growth work. Depending on relations cost and availability, as good as environmental considerations, a ME-GI engine gives shipowners and operators a choice of regulating possibly HFO or gas – primarily healthy gas. MAN Diesel Turbo has also grown an ME-LGI chronicle of a new record that is able of handling on methanol, and is now building an ME-LGI chronicle able of regulating on LPG, a latter being deliverable from Q2, 2018.

MAN Diesel Turbo sees poignant opportunities outset for gas-fuelled tonnage as concerns about both CO2 and SOx glimmer increase. Indeed, investigate indicates that a ME-GI engine delivers poignant reductions in CO2, NOx and SOx emissions. Furthermore, a ME-GI engine – in contrariety to competing engines – has usually a negligible, unburnt gas slip, hence adding really small to a hothouse effects of such slips. In addition, a Diesel explosion element leaves no formaldehyde emissions. All together, this creates a ME-GI engine array a many environmentally-friendly record accessible for sea propulsion.

The vessel

Hartmann grown a supposed ‘Ethylene Carrier Eco Star 36K’ in team-work with engineering consultants HB Hunte Engineering and has already resolved a long-term agreement for a newbuilding and a sisters with Saudi Arabian petrochemical company, SABIC.

The new vessel form differs essentially from required gas carriers with a superstructures located during a bow, giving an optimised placement of weight and a consequent reduced direct for counterbalance water, heading to reduced fuel expenditure and emissions. The new ‘Svelte’ crawl pattern enables a vessel to urge seakeeping during aloft movement speeds and also improves fuel efficiency. Another poignant underline is a carrier’s innovative ‘Star Trilobe’ tank that allows an boost in load ability by scarcely 30%, shortening shipping costs by economies of scale.

The new vessels offer a load ability of 36,000 m3 any for liquefied gas cargoes down to -104°C. Presently, these vessels are a largest LEG-carriers worldwide, usually to be surpassed by a incomparable vessels in a new 5-vessel array formerly mentioned.
