Three large-scale regasification modules for China's first new built Liquefied Natural Gas (LNG) Floating Storage Regasification Unit (FSRU), the Transgas Power, built at the Hudong-Zhonghua shipyard in Shanghai for Dynagas, have been delivered at the end of March 2020.
The so called Regas modules were designed by Wärtsilä, with required equipment, including valves and instruments, being sourced from various suppliers. Cosco shipyard in Qidong was awarded the contract to fabricate the units.
The three regasification modules weigh 450 t, 80 t, and 240 t. In addition, Wärtsilä also supplied related regasification equipment comprising pumps, heat exchangers, valves, and instrumentation for installation in the engine room. Seawater and steam server as energy sources for the system, and water/glycol as the energy carrier in a combined loop. The plant consists of three trains, each with a capacity of 250 m standard cubic feet per day or approximately 500 m3/h, and a common suction drum.
A second FSRU being built at the same yard for Dynagas, also featuring the Finnish manufacturer's regasification modules, is scheduled for delivery in mid-July 2020.
