HELSINKI, Finland – Wärtsilä will supply integrated power generation and propulsion packages for three vessels being built for Pacific Radiance Ltd.
Two 86-m (282-ft) platform supply vessels (PSV) are to be built at the Huang Pu shipyard in China, while the Zhenjiang shipyard in China will build a hybrid anchor handling tug supply (AHTS) vessel with more than 210 ton bollard pull. The equipment is scheduled for delivery in 2013, and the vessels are due to be delivered to Pacific Radiance in the first half of 2014.
For the PSVs, Wärtsilä will supply four 6-cylinder Wärtsilä 26 in.-line main engines, thrusters, and the electrical and automation systems. The PSVs will utilize the Wärtsilä low loss concept (LLC) power distribution system for electric propulsion applications. These will be the first vessels built in China to install the LLC system.
For the AHTS, the company will supply two 6-cylinder Wärtsilä 32 in.-line main engines, two generating sets based on 6-cylinder Wärtsilä 32 in.-line engines, two controllable pitch propellers, thrusters, and the electrical and automation systems.
Pacific Radiance COO BH Lau said: "The Wärtsilä LLC system incorporates high redundancy, high efficiency, and fuel economy for the entire electric propulsion application. The design of the 690V switchboard and power distribution system gives less single failure consequences and more available power, better operability, and safety during the vessels’ dynamically positioned mode."
