Emergency disconnection tool
Published: 06 April, 2016
Allspeeds has supplied Webtool emergency disconnection tools to AKOFS Offshore for its subsea equipment orientation system (SOES) used to install subsea trees. The Webtool cutters are integrated within the SOES providing quick disconnection of the bundles of hydraulic jumpers and electrical flying leads in the event the vessel moves off-station.
Deployed on the Skandi Santos subsea equipment support vessel, the SOES enables installation of subsea trees in approximately half the time it takes a conventional rig. In an emergency disconnect situation, the Webtool integrated cutter will cut a bundle of 10,000psi hydraulic jumpers connecting the SOES to a subsea tree stack. The jumpers are cut in a single operation in less than 10 seconds.
Allspeeds has supplied four Webtool emergency disconnection tools for the SOES system. The hose bundle is manually loaded into the mouth of the hydraulically operated cutter during installation and remains there throughout the life of the SOES. Designed for deployment for extended periods subsea at 3000m water depth, Webtool disconnection cutter can be function tested in situ, ensuring the tool is ready for use in the event of an emergency.
“Webtool’s hydraulic emergency disconnection tool is an important part of intervention contingency planning. Once activated the speed and completeness of the cut ensures companies can respond effectively to any emergency,” said an AKOFS Offshore spokesperson.
Webtool’s emergency disconnection tool is part of the Webtool range of high performance cutting tools, designed and manufactured exclusively by Allspeeds Ltd.
