Wärtsilä Power for Yacht-Carrying Pioneer

Posted on April 19, 2005

Wärtsilä Corporation has been awarded an order to supply the 19.7MW power plant for a yacht carrier contracted by the heavy transport specialist Dockwise Shipping BV, based in Breda in the Netherlands.

The yacht carrier has been ordered from Yantai Raffles Shipyard in China with delivery due in autumn 2006. Its dimensions are: 205.34 m length overall, 32.2 m beam and operational draught of 5.80 m. The cargoes of yachts will be loaded by floating them over the deck, which measures 165 m long by 31 m wide, while the vessel is ballasted down. To protect the yachts the cargo deck is equipped with high side walls.

The new yacht carrier will be equipped with a 19 680 kW diesel-electric plant for propulsion, ancillary electrical power, and all shipboard electrical services. The plant will be powered by two Wärtsilä 12V38B main diesel generating sets, two Wärtsilä 6L20 auxiliary generating sets, and a 300 kWe emergency/harbour generating set. The generating sets will supply twin Lips CS3500 pull thrusters for propulsion.

Manoeuvrability will be enhanced by a 1.64 MW Lips CT225 transverse bow thruster. The two 5.1 MW azimuthing pull thrusters will each be equipped with a 4.0 m-diameter Lips skewed, pulling, controllable-pitch propeller and Sternguard MK2M shaft seals. This is one of the first vessels to be equipped with Lips pull thrusters. The propeller is arranged ahead of the pod to achieve the best overall hydrodynamic efficiency and steering at high ship speeds.
