Recently, the “Design Scheme for Ammonia Fuel Bunkering via Terminal Tank Trucks,” independently developed by CSSC Hengyu Energy (a subsidiary of China State Shipbuilding Corporation), successfully secured an Approval in Principle (AIP) from the classification society Bureau Veritas (BV). As the first certificate of its kind issued in China for this model, this milestone marks a breakthrough in zero-carbon fuel bunkering technologies. It provides significant momentum for the shipping industry’s deep decarbonization efforts.
As a professional clean energy bunkering provider under CSSC, Hengyu Energy is committed to becoming a “leading domestic one-stop service provider for clean energy across the entire ship lifecycle.” The company has established a refueling ecosystem covering mainstream alternative fuels, including LNG, LPG, methanol, and liquid ammonia. It offers solutions for various fuel tank types—including Type B, Type C, and membrane tanks—and provides professional gas supply services to equipment manufacturers and stations. Recognizing fuel bunkering as the critical “last mile” in ensuring a ship’s operational readiness before delivery, the company leverages its technical expertise to support shipyard construction and key engineering projects.
In the ship repair and conversion market—a sector characterized by high technical barriers and complex operations—the company has also gained a competitive edge. Understanding the unique challenges of repair work compared to new building (such as complex processes and inconsistent standards), Hengyu Energy has developed a mature “vessel-specific tailored” service capability. It has successfully supported special inspections and modification projects for major international owners, including Germany’s Hapag-Lloyd and France’s CMA CGM, earning industry trust through reliable execution.
This AIP certification underscores Hengyu Energy’s technological innovation and commitment to green shipping. Looking ahead, the company will focus on the commercialization of green technologies, such as clean fuel bunkering. By continuously refining its clean energy service system and expanding its core technological advantages, the company aims to provide robust support for the global shipping industry’s transition to a green, low-carbon future.
