A MAN B&W 7G80ME-C9.2 engine passed its official shop test at HHI-EMD in South Korea.

The MAN Diesel & Turbo licensee reported that the shop test proceeded as expected and was a success. Engineers from MAN Diesel & Turbo took part in the entire prototype process, culminating with the very first engine start, then the official shop test and an overhaul inspection after that.

The engine is bound for a Greek customer – Almi Tankers – and will power a VLCC due for delivery by the Daewoo yard in May of this year with sea trials taking place in April. The new engine is the first of two in an identical package ordered by Almi with a second VLCC scheduled for delivery in December of this year.



Speaking at the time of the initial announcement of the Almi order, Ole Grøne – Senior Vice President Low-Speed Promotion & Sales – MAN Diesel & Turbo said: "Traditionally, super-long-stroke S-type engines, with relatively low engine speeds, have been applied as prime movers in tankers. Following the efficiency optimisation trends in the market, the possibility of using even larger propellers has been thoroughly evaluated with a view to using engines with even lower speeds for propulsion of particularly VLCCs.  We also see a clear trend with focus on fuel optimisation. We now have around 100 G-type engines on order, including the container and bulker segments, which is a successful introduction”.



He continued: “VLCCs may be compatible with propellers with larger propeller diameters than current designs accommodate, and thus higher efficiencies can be achieved following an adaptation of the aft hull design to accommodate the larger propeller. The new, ultra-long-stroke G80ME-C9 engine type meets this trend in the  VLCC market.

It is estimated that such new designs offer potential fuel-consumption savings of some 4-7%, and a similar reduction in CO2 emissions.  Simultaneously, the engine itself  can achieve a high thermal efficiency using the latest engine process  parameters and design features.
