The No 2 vessel of Phase Ⅱ of China’s largest-scale liquefied natural gas (LNG) carrier construction project was recently named Greenergy Sea and delivered at Changxing Island in Shanghai.
The project, initiated by China National Offshore Oil Corporation (CNOOC), aims to enhance the corporation’s ocean shipping capacity. Eight of the 12 vessels scheduled to be built in the project have been delivered.

The vessel, employing the fifth generation of China’s independently developed hull design, is 299 meters in length and 46.4 meters in breadth. It can carry 174,000 cubic meters of LNG in one trip, meeting the monthly demand of 7 million households.
The vessel is fitted with the newest version of the cargo containment system, significantly reducing the natural evaporation rate within its cargo tank to 0.085 percent. It is also equipped with an LNG cryogenic unit to further reduce evaporation.
Its main engine, equipped with an intelligent exhaust gas recirculation system and a water treatment system, can consume both oil and gas in compliance with the International Maritime Organization’s Tier Ⅲ oxynitride emission requirement.
Compared with vessels of the fourth generation of China’s hull design, it consumes less energy, boasts a more compatible tank type, has better carrying capacity and is more suitable for ocean transport routes.
The eight LNG carriers of the Greenergy series that have already been delivered are deployed to provide service that reaches more than 50 terminals across five continents.
The remaining four carriers are under steady construction. The No 3 vessel of the Phase Ⅱ project is ready to be delivered after several preparatory tasks; No 4 will undertake a trial sail when it is well prepared; No 5 is undergoing equipment testing; and No 6 is undergoing multiple examinations on device installation and invar leak tightness.
All of the project´s vessels are expected to be delivered by the end of 2027.
