Recently, SunRui's self-developed Marine ammonia fuel supply system (AFSS) has been awarded the world's first LR and CCS Classification Society Approval in Principle (AIP) certificate. The successful development of AFSS by SunRui is another major breakthrough in the field of clean energy supply systems for ships, following the LNG supply system for ships and the methanol fuel supply system for ships.

At present, ammonia is widely considered as one of the fuels with wide application prospects in the green and low-carbon transformation of the shipping industry. Under this context, SunRui and LR Classification Society signed a strategic cooperation agreement on technical cooperation in the application of marine clean energy such as ammonia fuel.

Through unremitting efforts, SunRui developed AFSS with completely independent intellectual property rights. The key technologies of liquid ammonia bunkering, fuel storage, fuel supply and ammonia vapour processing have been mastered. The supply technical route of "two-stage temperature regulation, two-stage pressurization and one-stage filtration" has been formed. The system is mainly composed of bunkering unit, ammonia storage unit, heat exchange and supply unit, ammonia vapour processing unit, security and monitoring system, control system and other units. The system is suitable for MAN-ES two-stroke ammonia engine ME-LGIA and WinGD two-stroke ammonia engine.

Due to the toxicity and corrosion of ammonia fuel, during the certification period, LR Classification Society, CCS Classification Society and SunRui conducted a comprehensive risk assessment of AFSS in key links of ammonia fuel. The assessment includes bunkering, storage, supply, ammonia vapour processing, ventilation and layout. During the risk assessment, LR, CCS and SunRui should identify potential safety hazards in each step. Meanwhile, corresponding protective measures should be discussed and risks should be rated to ensure the safety and reliability of AFSS design.

In recent years, SunRui has always been steering to a greener future. The company has developed a series of products such as EGCS、SCR、FGSS、LFSS. The development and application of these products for SunRui have accumulated rich experience in technical application and are highly recognized by customers. The successful development of AFSS and the AIP certification of LR and CCS indicates that SunRui has reached a new level in the field of ship clean energy application. Under the opportunity of global low-carbon environmental protection, SunRui will continue to provide customers with the most efficient and economical Marine environmental solutions and provide support and contribution to the green development of the global shipping industry.
