The world’s largest LNG bunkering vessel completes first ship-to-ship bunkering

China’s first domestically built LNG bunkering vessel has completed its first ship-to-ship bunkering operation.

The bunker operation was completed on Jan. 18 and saw the 30,000 cubic meter LNG bunker ship Hai Yang Shi You 301 (Offshore Oil 301) refuels CMA CGM’s 23,000 TEU dual-fuel container ship CMA CGM Concorde at Yantian Port, Shenzhen.

The China Classification Society (CCS) provided on-site assistance to facilitate the process.

The vessel contains China’s first domestically developed LNG ship-to-ship bunker system jointly developed by China State Shipbuilding Corporation (CSSC) and global energy company CNOOC Energy Development Co., Ltd.

According to the CSSC, the system consists of emergency release devices, quick connect devices, cryotubes, vessel distance sensing devices, saddles and fall arrest systems. The system has a designed bunker capacity of 1650 m³ per hour.

According to the CSSC, the bunkering has demonstrated that the system can enable safe and rapid inter-vessel LNG filling and that the development of the system strengthens the production capacity of China’s marine LNG industry chain.

The bunker vessel was delivered to China National Offshore Oil Corporation (CNOOC) in November 2022 following a conversion project at China State Shipbuilding Corporation’s subsidiary Guangzhou Shipbuilding International (GSI). The entire conversion process was overseen by CCS, who also carried out the necessary risk assessments and classified the ship once the conversion was complete.

The ship has been described as the world’s largest LNG bunkering vessel due to its capacity.

The conversion is the first project of its kind in China and is part of the country’s national strategy to reach carbon peak and achieve carbon neutrality by switching to greener fuels.
