Chinese dredges to have MAN propulsion packages

Jiangsu Haihong Engineering Technology Co., Ltd. has ordered four MAN 32/40 engines in connection with an order for two 8,000 cu.m trailing suction hopper dredges.

The scope of delivery covers two shipsets, with each including a propulsion package consisting of two 9L32/40 engines, an MAN Alphatwin-screw VBS860 CP propeller, single marine reduction RSVL-800 gearboxes from Renk, plus a Selective Catalytic Reduction (SCR) system that enables the engines to fulfill Tier III in liquid mode.

Jiangsu Haixin Shipping Heavy Ind. will construct the vessels at its shipyard in China with delivery scheduled for end-2016, and MAN Diesel & Turbo will build the engines at its Augsburg plant in Germany.

"This new project is an excellent reference for us in the Chinese market," said Lex Nijsen – Vice President and Head of Four-Stroke Marine – MAN Diesel & Turbo. "It is of especial interest to MAN Diesel & Turbo in that these two newbuildings will be identical, sister vessels to a dredge previously ordered by Jiangsu, but whose propulsion packages did not feature MAN engines. We are delighted that Hai-Hong has decided to place its confidence with MAN and look forward to a successful collaboration with our Chinese partners."

The 32/40 engine is considered in the industry as a proven workhorse that commonly sees service for 24 hours a day with a power output that ranges from 3,000 to 9,000 kW. Low wear-rates and long maintenance intervals are engine characteristics with output limited to 100% of rated output for engines driving a propeller, and 110% of rated output for engines driving a generator.
