Wärtsilä Integrated Systems: Driving Innovation in SIPG’s New LNG Bunkering Vessel
In a significant advancement highlighting the maturity of the global liquefied natural gas (LNG) bunkering market, Wärtsilä Gas Solutions has secured a contract to supply a complete set of integrated systems for a new LNG bunkering vessel. This vessel is being constructed at the Jiangnan Shipyard in China for Shanghai International Port Group (SIPG) Energy Shanghai Co., marking a major milestone in the maritime industry.
The repeat order, recorded by Wärtsilä in the third quarter of 2025, underscores the sector’s trend towards sophisticated and integrated systems that ensure maximum efficiency and performance in critical bunkering operations. This decision not only reflects strong confidence in Wärtsilä’s technological solutions but also a vision towards a more sustainable and efficient future in LNG management.
For maritime industry professionals and investors in clean energy technologies, this news presents an opportunity to engage in a project that is not only innovative but also crucial for advancing towards cleaner fuels in the shipping industry. Staying up to date with such technological advancements is essential to remain competitive in an increasingly demanding global market.
Wärtsilä’s Integrated Solution Details
Wärtsilä Gas Solutions will provide a comprehensive and fully integrated package to the new bunkering vessel, ensuring that all key functions, from cargo storage to fuel gas management, operate in perfect synergy. This approach will ensure more efficient cargo management and better environmental and economic performance for the vessel. The package includes three critical interconnected systems: Cargo Handling System (CHS), Fuel Gas Supply System (FGSS), and Boil-Off Gas Reliquefaction System (Compact Reliq – CRS).
The full integration of these systems optimizes cargo management efficiency, reducing losses and improving operational safety. These integrated systems are not only beneficial for the vessel’s efficiency but also represent a significant improvement in terms of sustainability. By preventing methane release into the atmosphere, these systems directly support decarbonization goals, which are crucial for the future of international maritime transport.
- Efficient cargo management
- Environmental sustainability
- Operational safety
The Compact Reliq (CRS): A Key Piece of the Puzzle
The inclusion of the Compact Reliq (CRS) reliquefaction unit is a fundamental technical aspect of the project. This advanced system is designed to handle natural boil-off gas (BOG) produced in LNG cargo tanks. By reliquefying this gas and returning it to the tanks, the CRS system minimizes cargo losses and maintains stable pressure within the cargo tanks.
The conversion of BOG back to marketable liquid cargo maximizes bunkering cargo efficiency, ensures safe operation throughout all phases, and contributes to emissions reduction. These features not only enhance the economic efficiency of the operation but also reinforce the maritime sector’s environmental commitment.
- Efficient reliquefaction of BOG
- Enhanced operational safety
- Environmental impact reduction
SIPG’s Commitment to Operational Excellence
The choice of Wärtsilä by the Shanghai International Port Group (SIPG) is a strong vote of confidence based on established operational performance. He Bin, Deputy General Manager of Shanghai SIPG Energy Service Co. Ltd., highlighted the successful track record with their vessel equipped with Wärtsilä systems, which motivated collaboration on this new project.
With over 200 bunkering operations conducted and more than one million cubic meters of LNG handled, SIPG has demonstrated exceptional commitment to operational efficiency and sustainability. This accumulated experience in LNG bunkering vessel operation provides valuable insights that will be used to further enhance the performance of the new project.
Enhanced Performance and Optimization
The collaboration between SIPG and Wärtsilä goes beyond simple technology supply, focusing on optimization through shared operational experience. Barry Yang, General Sales Manager, China, Wärtsilä Gas Solutions, emphasized the need to meet the increasing demand for LNG as a marine fuel.
The demand for LNG continues to rise, and Wärtsilä is positioned as a leader in supplying modern and reliable systems that optimize cargo management for LNG bunkering vessels. SIPG’s rich operational experience in LNG bunkering vessels provides valuable input for vessel optimization, elevating the system to a new level of performance.
- Optimized cargo management
- Meeting rising LNG demand
- Strategic collaboration for sustainability
A Promising Future for LNG Bunkering
The project is scheduled for delivery in 2026, with the vessel expected to be operational by the summer of 2027. This timeline, along with the strong track record of the involved partners, suggests that the project will not only meet expectations but also set new standards in the industry.
