Hydraulic Power Unit Control System[Back to top]
The Emergency Control System is controlled by the KLAW LNG Hydraulic Power Unit (HPU). This allows the emergency release of all the manifold connections in a matter of seconds.
The KLAW HPU is a critical element in the correct and successful operation of the LNG Emergency Release System.
The HPU system offers the operator a single point of control over the ERS which means an ERC can be activated for other reasons beyond stress on the hose line.
There are many control variables that can be integrated into the HPU system including automated options. These control variables facilitate the release of the couplings under different scenarios and conditions.
The HPU can operate a single ERC or a system of up to 10 ERC units.
This HPU can be electric or air driven.
The HPU is also used to reset the ERC following activation.
HPU integrated redundancy features[Back to top]
The KLAW HPU is a critical element within the LNG safety system and possesses integrated series parallel backup systems to ensure functionality. This extensive range of redundancy features is designed to accommodate every perceived eventuality.
The functions of the KLAW HPU[Back to top]
The KLAW HPU delivers four functions; these are the Hydraulic circulating system, Hydraulic high pressure system, Manual Release with ship ESD (Emergency Shut Down) event and Automatic release with ESD event.
Modes of operation[Back to top]
The KLAW HPU provides several modes of operation including Manual, Automatic and Automatic On-vessel Separation.
Emergency Shut Down (ESD) integration[Back to top]
The KLAW HDU can be integrated with the vessel’s ESD system.
Automatic Sequence Release System (ASRS)[Back to top]
The HPU has a fully automatic release function which would instigate an ERC separation in the event of unplanned or unexpected ship to ship separation.
Power supply backup systems[Back to top]
The KLAW LNG HPU offers power backup systems to counter power supply failure.
