A new type of LNG Carrier vessel being built for Singapore based Saga LNG Shipping will be constructed at China Merchants Heavy Industry’s Haimen based shipyard in China’s Eastern Jiangsu province and is set to be delivered in early 2018. Wärtsilä has been contracted to supply the complete cargo handling system including the fuel system, as well as the dual-fuel main propulsion system. The contract with Wärtsilä was signed in November.
Wärtsilä’s scope of supply includes a comprehensive propulsion package comprising a 12-cylinder Wärtsilä 50DF dual-fuel main engine, 6-cylinder and 8-cylinder Wärtsilä 20DF dual-fuel generating sets, a Wärtsilä controllable pitch propeller (CPP), a Wärtsilä Energopac efficiency rudder, a Wärtsilä gearbox, and a Wärtsilä tunnel thruster.
The 45,000 m3 capacity carrier is designed with a new LNT A-BOX® containment system, and the owners specified world class suppliers with leading technologies to ensure that the vessel meets the highest standards.
The Wärtsilä cargo handling system for LNG carriers has an integrated fuel system utilizing both compressors and forced vaporizing. The automation and safety control systems are state-of-the-art, while the Wärtsilä cargo pumps include the EFP pump series, the latest development for LNG fuel and spray. The total solution package comprising the cargo and propulsion systems is designed to attain maximum overall efficiency for the vessel, thereby producing notable savings in operating costs. Furthermore, the total solution concept minimizes interfacing and system design risk during the vessel building process.
“This will be a very modern and highly efficient LNG Carrier and we were selected because our technologies in both the propulsion equipment and cargo handling are world leading. The new ship has been designed for worldwide trade of LNG, but with special consideration given to the reloading of cargoes and local and regional trading. Therefore, the cargo handling system and the fuel efficiency of the engine have to be the most efficient possible. Our unmatched track record with proven LNG technologies and dual-fuel solutions was a key factor in the award of this valuable contract,” says Timo Koponen, Vice President, Flow and Gas Solutions, Wärtsilä.
Delivery of the Wärtsilä equipment to the yard will commence in late 2016.
