MAN Diesel & Turbo’s latest G-type engine passed, at the end of April, its Type Approval Test at HHI-EMD, the engine and machinery division of Hyundai Heavy Industries in Korea.
The ultra-long-stroke G60ME-C9 engine went through its paces under the watchful eye of many interested observers, including representatives from the major classification societies.
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 the fastest market acceptance any engine series in the MAN B&W portfolio has ever received.
The engine is due to power a tanker owned by Istanbul-based Densa Tankers, the international ship management and chartering company specialising in oil and chemical tankers. The vessel will be managed by Thome, the Singapore-based provider of global, integrated ship management services.
The G-type programme
MAN Diesel & Turbo’s G-type programme 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 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 optimised engine design, this reduces fuel consumption and reduces CO2 emissions.
MAN Diesel & Turbo believes that, just as MAN B&W S-engines became first choice for container ships, G-engines will become first choice for bulkers, tankers and some box ships.
