FGSS

1. Industry Demand

As the core of marine clean energy power, FGSS (Fuel Gas Supply System) involves LNG vaporization, gas preheating and system cooling. With LNG stored at -162℃, the system demands extreme low-temperature resistance and zero-leakage performance. Marine operating conditions feature high salt fog, continuous vibration and extreme temperature fluctuations. Heat exchangers must deliver reliable low-temperature adaptability, anti-corrosion capability, vibration resistance and ultra-safe sealing to ensure stable gas supply and navigation safety without leakage or structural failure.

2. Core Working Stations

Core scenarios include high-efficiency LNG cryogenic vaporization, constant-temperature gas preheating and pressure stabilization, FGSS loop cooling and heavy-duty anti-vibration heat reinforcement. Widely applied in LNG-powered merchant ships and offshore platforms, it ensures stable power output, zero leakage risk and long-cycle reliable operation under harsh marine environments.
