Wärtsilä to Supply Integrated Cargo and Fuel Systems for New LNG Bunkering Vessel

Wärtsilä Gas Solutions has secured a contract to deliver a fully integrated package of cargo handling, fuel supply, and boil-off gas reliquefaction systems for a new LNG bunkering vessel being built for Shanghai International Port Group (SIPG) Energy Shanghai Co. The vessel is under construction at Jiangnan Shipyard in China, and Wärtsilä booked the order in the third quarter of 2025.

Integrated Systems for LNG Bunkering

The scope of supply includes Wärtsilä’s cargo handling system, fuel gas supply system, and the Compact Reliq (CRS) boil-off gas reliquefaction unit. All systems will be fully integrated to support operational efficiency during bunkering operations.

SIPG’s Operational Experience

He Bin, Vice General Manager of Shanghai SIPG Energy Service Co. Ltd., said the company’s experience with existing Wärtsilä-equipped LNG bunker vessel Hai Gang Wei Lai influenced the decision.
“During the recent three and a half years after we took over Hai Gang Wei Lai, we have finished more than 200+ bunkering of 1 million+ m3 LNG for various ships calling Shanghai port. We are satisfied with the performance of Wärtsilä systems and this is the reason we are working with them again in this new project,” he said.

Rising LNG Fuel Demand

According to Wärtsilä, demand for LNG as a marine fuel continues to rise, driving the need for efficient bunkering infrastructure.
“The demand for LNG as a marine fuel continues to increase, and we are a leader in supplying modern and reliable systems that optimize overall cargo handling efficiency for LNG bunkering vessels. SIPG has rich operation experience in LNG bunkering vessels and provides valuable input for the vessel’s optimization. We are working closely with the owner and shipyard to implement improvements, which will elevate the system to a new level of performance,” said Barry Yang, General Manager Sales, China, Wärtsilä Gas Solutions.

Delivery and Commissioning Timeline

Wärtsilä expects to deliver the equipment to Jiangnan Shipyard in 2026. The vessel is scheduled for commissioning in the summer of 2027.
