ERC Coupling System

Alpha Process Control’s Emergency Release Collar (ERC) couplings help support liquefied natural gas (LNG) transfer to floating storage regasification units. The couplings incorporate an engineered solution to handle low pressure drops, ensuring that the transfer can achieve high flow rates. Installed aboard the FSRU, they are part of the pipeline that connects to the LNG carrier. They feature a two-stage operation that enables controlled shutdown of internal valves and coupling separation, and they can be operated mechanically or through an operator controlled separation.
