MAN Engine Passes First Test

7G80ME-C9.2 to power Almi Tankers’ very large crude carriers (VLCC); ultra-long-stroke engine to power larger propellers

Posted on February 6, 2013

The engine and machinery division of Hyundai Heavy Industries (HHI-EMD) has reported that the world’s first MAN Diesel & Turbo B&W 7G80ME-C9.2 passed its official shop test in Korea.

MAN engineers took part in the entire prototype process, culminating with the very first engine start, the official shop test and an overhaul inspection.

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.

MAN said that it has traditionally applied its super-long-stroke S-type engines, with relatively low engine speeds, as prime movers in tankers. Following the efficiency and fuel optimization market trends, the company said it evaluated the possibility of using even larger propellers with a view to using engines with even lower speeds for propulsion, particularly of VLCCs.

The company said that VLCCs would be compatible with larger diameter propellers following an adaptation of the aft hull design to accommodate the larger propeller. MAN estimates that such designs offer potential fuel-consumption savings of some 4 to 7% and a similar reduction in CO2 emissions.
