Wärtsilä to power eleven new Spliethoff Group vessels

Shanghai:  Wärtsilä has recently been awarded two large orders from the Amsterdam-headquarted Spliethoff Group for propulsion systems for eleven ships to be built at the Ouhua Shipyard in Zhejiang, China. The Wärtsilä scope of delivery includes engines, propellers and efficiency rudders, as well as bow thrusters forming a complete integrated propulsion system for the ships.

The new orders are for five 16,800 dwt Heavy-Lift vessels to be operated by BigLift Shipping, and six 12,500 dwt Multipurpose vessels. Deliveries of the Heavy-Lift vessels will take place between August and December 2010, and the Multipurpose vessels will be delivered between December 2010 and May 2011. With these additional newbuildings the total order book is now about 20 vessels under delivery with Wärtsilä propulsion solutions for the Spliethoff Group.

"These new contracts strengthen the successful and long-standing relationship between Spliethoff and Wärtsilä. More than 60 Spliethoff vessels in operation are equipped with Wärtsilä propulsion systems" says Reinier de Vries, senior account manager, Wärtsilä in the Netherlands.

For the Heavy-Lift vessels, Wärtsilä's scope includes an 8-cylinder in-line Wärtsilä 46 main engine with an output of 8400kW at 500 rpm, a controllable pitch (CP) propeller, a Wärtsilä Energopac efficiency rudder, and a bow thruster.

"The propulsion technology carried by these vessels has been effectively optimized by designing an efficient rudder/propeller combination, and by employing a six-metre propeller. Wärtsilä used both computational fluid dynamics (CFD) and full-scale tank tests in finalising the design," de Vries added.

For each Multipurpose vessel, Wärtsilä will be delivering a 6-cylinder in-line Wärtsilä 46 main engine with an output of 5430kW at 500 rpm, a CP propeller and bow thrusters. The design of the engine and propeller is said to allow the customer to achieve maximum fuel efficiency.  [16/12/09]
