New APC coupling receives Class Approval

Published by
LNG Industry,


Alpha Process Controls (APC) has announced that it has received Class Approval for its new 4 in. marine emergency breakaway coupling for use in LNG transfer.

ClassNK has accredited the latest addition to APC’s family of emergency release couplings (ERC), following extensive independent testing of the  system, which can also be employed for the transfer of hazardous chemicals, cryogenic liquids and gas.

The new system incorporates a simple cable release mechanism, which eliminates the need for  hydraulic power units to perform shutdowns in the event of ship-to-ship or ship-to-shore separation. 

The company’s couplings feature an emergency release system, including a two-stage operation that enables the controlled shutdown of internal valves before instigating a coupling separation. 

Through controlled shutdown of the ERC, pressure surges are maintained to a level without compromising pipework or pumps in the event of a vessel drift-away. 

John Lamb, Managing Director of APC, said: “Achieving Class Approval for our 4 in. ERC coupling from a globally-recognised society is a significant endorsement of the extensive research and development we have undertaken to bring this system to market.

“Demand for LNG is growing, in part due to its application as a fuel for ships and ferries, which in turn has increased the focus on the importance of safe and efficient transfer. 

“Extending our family of couplings, which now range from 4 to 10 in. […] enables Alpha Process Controls to meet a wider range of customer requirements and help influence increased safety in the industry through the application of cutting-edge technology.”
