LNG Emergency Release Couplings
KLAW LNG Emergency Release Couplings (ERCs) offer safe and identified parting points within the LNG hose transfer system. The ERC is normally positioned between the manifold of the receiving vessel and the hose. The ERC operates at cryogenic temperatures.
Shutting off transfer flow in an emergency[Back to top]
In an emergency, the ERC separates and the valves close. The double valve closure shuts off the downstream and upstream LNG flow on each side of the separation.
Instant closure[Back to top]
The instant closure of the KLAW Flip-Flap valve mechanism within the ERC delivers the crucial advantage of minimal spillage.
Controlled closure[Back to top]
The KLAW ERC range offers controlled closure options. This delivers additional control over flow shut down.
Compact and lightweight[Back to top]
Compared to other options, the KLAW ERC is compact and lightweight and given the challenging conditions of the offshore environment, this is a valuable feature. Installation, maintenance and handling of the ERC on activation and reinstatement along with operation and management in confined spaces is much easier.
The KLAW STS LNG transfer system is a mobile system that can be transferred from and to any vessel if required.
Efficient flow transfer[Back to top]
The KLAW Flip-Flap design provides minimal flow restriction and therefore low pressure drops.
KLAW ERC sizes[Back to top]
KLAW LNG offers ERC systems in all sizes up to 10” NB. Larger sizes can be provided on application.
Cryogenic and ambient temperature cycles[Back to top]
The KLAW LNG ERC is designed to meet the demands of cryogenic to ambient temperature cycles
The operating temperature of the LNG transfer system is cryogenic. When not commissioned, the system returns to an ambient temperature which in itself can vary depending on the environment in which the system is operating. KLAW LNG transfer systems are designed to sustain these repeated extreme temperature cycles.
