Application Summary AI generated
GB/T 38520-2020 specifies the design, performance, and testing requirements for marine cryogenic breakaway couplings used in liquefied gas transfer systems. It applies to ship-to-ship or ship-to-shore loading and unloading operations for cryogenic fluids such as LNG, ensuring automatic separation under excessive tension to prevent hose rupture and leakage. This standard is critical for safety in maritime fuel transfer, particularly in LNG bunkering and offshore gas handling.
