LNG carriers to feature Wärtsilä systems

LNG Industry,

Four new LNG carriers being built by the Hudong-Zhongua Shipbuilding yard in China will feature Wärtsilä LNG reliquefaction plants and gas handling systems.

The ships are owned by Teekay, China LNG Shipping, CNOOC Energy Technology, and BW Gas. The contracts with Wärtsilä were issued by Hudong-Zhonghua Shipbuilding and were signed during 4Q14.

The award of these contracts is a break into the Chinese market for Wärtsilä LNG reliquefaction plants and gas handling systems for LNG carriers.

BOG reliquefaction

The reliquefaction plant will reliquefy 70% of the boil-off gas (BOG) from the ships' LNG cargo and return it to the cargo tanks, while the balance is fed by the gas handling system to the engines for propulsion purposes. The system is pre-fabricated in skid modules for easy onboard installation and hook-up. It can be stopped when the cargo pumps are in operation, reducing the need for extra generator capacity.

For both the LNG reliquefaction plant and gas handling system, Wärtsilä will provide engineering support, system responsibility and associated process guarantees.


Commenting on the contract award, Timo Koponen, VP, Flow and Gas Solutions, Wärtsilä Ship Power, said: "Wärtsilä was selected because we were able to offer the best technical solution with the lowest capital and operational expenditures. Our in-house know-how and experience is unmatched in the industry, which is why the leading gas carrying operators consistently opt for Wärtsilä's state-of-the-art solutions."

The first of the 174 000 m3 LNG carriers is scheduled for delivery in September 2017, with two to follow in 2018 and the last ship in January 2019.
