Wärtsilä technology for Chinese 38,000 tonne semi-submersible heavy-lift vessel
May 31, 2010 - Wärtsilä, the marine industry's leading ship power systems integrator, has signed a contract to deliver a ship power system for a 38,000 tonnage semi-submersible heavy-lift vessel for Chinese customer Zhejiang Share-ever Business Co., Ltd. Wärtsilä's solution was selected for its proven reliability, and because of the first class global service support the company is able to provide.
Zhejiang Share-ever Business Co., Ltd is a privately owned company with more than 20 large-size vessels, including 72m offshore platform supply ships, ocean cargo carriers of between 27,000 and 50,000 tonnes, and drag-suction dredgers. The company seeks to utilize the latest marine technologies and works closely with domestic vessel design institutes.
Zhejiang Share-ever Business Co., Ltd is a new customer to Wärtsilä. "Wärtsilä is a well-known name in the marine industry and has proven itself to be worthy of our trust," said Mr Xia, President of Zhejiang Share-ever Business Co., Ltd.
This vessel will operate in offshore waters around the world, and will be mainly used in loading and transporting large-size offshore equipment required by the offshore oil and gas industry. Such equipment includes large-size steel structures, various kinds of platforms, platform jackets, and main platform blocks, etc. used in prospecting and exploration. The vessel will also assist large commercial vessels and naval ships in re-floating and similar operations. The vessel will be delivered in the end of 2011.
Reliable power generation
The engine configuration is based on the proven Wärtsilä 32 medium speed engines. The scope of supply includes three 9-cylinder in-line Wärtsilä 32 generating sets for a diesel electric installation, and three tunnel thrusters.
