Wartsila dual-fuel engine chosen for LNG carrier
HELSINKI, Finland -- A 5-cylinder Wartsila RT-flex50DF engine, together with the gas valve unit and other relevant equipment, has been ordered for a new LNG carrier vessel being built for the Chinese ship owner and operator, Zhejiang Huaxiang Shipping Co.Ltd.
The Qidong Fengshun Ship Heavy Industry Co., Ltd in China is building the new vessel according to the Chinese Class Society standards. The contract was signed in March 2014. When delivered in August 2015, the 14,000 cubic m LNG carrier will operate along the Chinese coastline to serve domestic LNG transportation lines.
Wartsila unveiled its low-pressure, dual-fuel technology for 2-stroke engines in November. It offers significant capital expenditure and operating expenditure benefits, and in gas mode is compliant with the IMO' s Tier III emission regulations without need of any exhaust gas cleaning systems.
The new 2-stroke DF application makes the use of LNG fuel available to virtually all vessel types. The Wartsila RT-flex50DF engine is the first of the new series to be manufactured. Wartsila' s low pressure LNG concept is a lean burning Otto-cycle gas engine that has additional liquid fuel back-up capability, thereby enabling vessels to operate 100% on LNG.
Zhejiang Huaxiang specialises in the safe transportation of LNG, and is one of the only two companies who have the Business Certificate of LNG transportation in coastal China issued by the Ministry of Transport of the People' s Republic of China.
