Latest MAN B&W G-type completes type approval test

G-type TAT4MAY 16, 2013 — MAN Diesel & Turbo’s reports that its latest G-type engine recently passed its type approval test (TAT) at HHI-EMD, the engine and machinery division of Hyundai Heavy Industries. The ultra-long-stroke G60ME-C9 engine was put through its paces under the eye of a large number interested observers, including representatives from the major classification societies.

The engine will power a tanker owned by Istanbul-based Densa Tankers that will be managed by Thome.

Christian O. Rasmussen, Head of Classification Business, MAN Diesel & Turbo, praised the collaboration between his company and HHI-EMD and said: “Our 600-mm bore engines have enjoyed much market success because of their reliability. The new G-type continues this legacy, as confirmed by the successful TAT here in Korea.”

He continued: “The G60 engine represents the culmination of many years’ development work. In these uncertain times for the shipping industry, MAN Diesel & Turbo sees significant opportunities arising for G60 as fuel prices continue to rise.”

MAN Diesel & Turbo reports having close to 200 G-type engines on order, spread over a broad spectrum of applications and a number of different licensees – with HHI-EMD leading the field – and states that it has had the fastest market acceptance any engine series in the MAN B&W portfolio has ever received.

The G-type program entered the market in October 2010. The G-types have designs that follow the principles of the large-bore, Mark 9 engine series that MAN Diesel & Turbo introduced in 2006. Their longer stroke reduces engine speed, thereby paving the way for ship designs with unprecedented high-efficiency.

G-type engines’ longer stroke results in a lower rpm for the engine driving the propeller. This lower optimum engine speed allows the use of a larger propeller and is, ultimately, significantly more efficient in terms of engine propulsion. Together with an optimized engine design, this reduces fuel consumption and reduces CO2 emissions
