A series of four LNG carriers being built by the Hudong-Zhongua Shipbuilding yard in China will feature Wartsila LNG reliquefaction plants and gas handling systems.
The ships are owned by Bermuda based Teekay Corporation, China LNG Shipping (CLNG), CNOOC Energy Technology Co of China, and BW Gas of Norway. The contracts with Wartsila were issued by Hudong-Zhonghua Shipbuilding and were signed during the fourth quarter.
The award of these contracts is a significant breakthrough into the Chinese market for Wartsila LNG reliquefaction plants and gas handling systems for LNG carriers, while at the same time emphasising the company’s position as the market leader in supplying these solutions.
The Wartsila solutions will provide the owners with both economic and technical benefits. The reliquefaction plant will reliquefy 70% of the boil-off gas 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, thereby reducing the need for extra generator capacity. No extra personnel are required for operation and maintenance.
