MAN Energy Solutions Supplies Propulsion, Propellers for German Tankers

Fuijan Mawei Shipbuilding and Xiamen Shipbuilding Indsutry have ordered four MAN 10L32/44CR main engines for the construction of four 41,000 dwt oil-and-chemical tankers for German Tanker Shipping (GTS). The Swedish Fartygskonstruktioner AB-designed quartet will be built at Xiamen Shipbuilding with delivery scheduled from mid-2025 onward. The propulsion order includes options for two additional vessels.

“This entire project is testimony to the decades-long cooperation between GTS and MAN Energy Solutions,” said Lex Nijsen, Vice President, Marine Europe and Americas, MAN Energy Solutions. “It’s a notable feather in our cap to have been selected as propulsion-system supplier for these ice-classed newbuilds.”

Each main engine has a power output of 600 kW per cylinder and comes integrated with a proprietary low-pressure selective catalytic reduction (LP-SCR) system that reduces NOx rates by up to 90%. The engines will drive a MAN Alpha VBS1260 CP propeller with a Flender GUCK-1560 gearbox.

These vessels will also feature auxiliary engines in the form of two 8L23/30H Mk2 gensets and one 6L23/30H Mk2 genset. CSSC Marine Power, a MAN Energy licensee, will build the gensets in China.

“In this particular order, we are using our newest technology by fitting the ships with water-lubricated stern tubes. In doing so, we are ensuring that there is no ‘oil-to-water interface’, eliminating any possibility of oil leaks and boosting the owner’s green profile,” said Jens Munch, Sales Manager, MAN Alpha Frederikshavn, MAN Energy Solutions. “Such stern tubes are one of the biggest eco-trends that we foresee in the market and we have proven technology available based on our great experience with naval vessels where this solution has been used for many years.”

MAN Energy’s common-rail engines are capable of burning conventional fuels such as HFO, MDO, and MGO, as well as sustainable fuels like biodiesel. The engines are also designed ready for retrofit to methanol operation as green fuel, if this should be desired at a later stage. The SaCoS 5000 engine automation system for the 32/44CR allows it to fulfill cyber security requirements and facilitates remote technical support.

“The MAN 32/44CR engine maintains high efficiency at all times and there is no fuel penalty or de-rating when operating the SCR system, especially with HFO,” said Christian Kamm, Sales Manager Europe, Marine, MAN Augsburg. “This is in great part due to the lower temperature that MAN SCR solutions operate at and that meet the highest emission standards.”
