AFSS

Overview of the AFSS

The Ammonia Fuel System consists of several essential components, including the filling and storage system, the Ammonia Fuel Supply System (AFSS), the Fuel Value Unit (FVU), the vent system, the Ammonia Release Management System (ARMS), the ventilation system, the inert gas system, the internal engine ammonia fuel system, and the safety system. Notably, there are distinct differences between the systems of MAN and WinGD.

Product Parameters

Product Details

1. Safety and Efficiency – The system ensures the safe and efficient bunkering and storage of ammonia, complying with strict regulations for handling low-flashpoint fuels. It is specifically designed to meet IMO regulations and industry standards for ammonia as a marine fuel.

2. Flow Control and Safety Features – With the ability to precisely control ammonia flow, the system ensures safe operations. It is equipped with advanced safety features such as leak detection, emergency shutdown systems, and integration with inert gas systems.

3. Environmental Protection – The system prevents environmental risks by capturing and treating ammonia vapor. It is designed with thermal oxidation or re-liquefaction systems to ensure the safe handling of ammonia, particularly within low-pressure storage tanks.

4. Ventilation and Risk Mitigation – This system ensures proper ventilation in both above-deck and enclosed areas, minimizing explosion risks by integrating inert gas systems to safeguard hazardous areas.

5. Pressure Maintenance – To maintain pressure within safe limits for low-pressure storage tanks, the system incorporates re-liquefaction or sub-cooling units. Alternatively, thermal oxidation systems can be used to handle excess ammonia vapor effectively.

Installation Process

1. Vessel Design Confirmation – Start by confirming the vessel design drawings and interface requirements for the system. Complete any necessary technical clarifications at this stage.

2. Preparation for Installation – Assemble all the required installation tools, equipment, and safety protection measures.

3. Transportation of Components – Transport the prefabricated fuel supply system module to the installation site, using lifting equipment to position it accurately in the designated area.

4. Module Fixation – Secure the base of the module to the ship's structure, ensuring stability and alignment according to design specifications.

5. Connecting Systems – Connect the transfer pipelines, auxiliary system piping, and control cables, ensuring proper sealing performance and electrical system integrity.

6. Debugging Procedures – Perform individual and integrated debugging of the supply system to verify the operational performance of subsystems, including bunkering, supply, and control safety functions.
