Wärtsilä power for super dredger
One of the world's largest non self-propelled cutter dredger vessels currently being built in China will be equipped with Wärtsilä engines, both to generate power and to drive the dredging pump.
The 6500 CBM vessel will be fitted with four 12-cylinder Wärtsilä 32 engines, two of which will be used to drive the dredging pump. For this application the 6000kW engines will run at 775 rpm instead of the normal 750 rpm. The Wärtsilä machinery is scheduled to be delivered in August 2015.
Hans Laheij, Wärtsilä Ship Power, said: “More Chinese ship owners and shipyards are selecting Wartsila for their vessels and this further strengthens our position within the Chinese shipbuilding market.”
Designed for reliability and easy maintenance, this medium speed engine is also used for generating set applications. The Wärtsilä 32 was developed in response to a need in the market for a new engine in the 320 mm cylinder bore class.
It is designed for efficient and easy maintenance in combination with long maintenance-free operating periods. The Wärtsilä 32 engine is fully compliant with the IMO Tier II exhaust emissions regulations set out in Annex VI of the MARPOL 73/78 convention.
The ship has been designed by the Design & Research Institute of Ship and Ocean Engineering at Shanghai Jiaotong University and is being built for Jiangsu Haihong Construction Engineering Co.
When delivered, the vessel will operate in the South China Sea and in Middle Eastern waters.
