Norway-based AKOFS Offshore has selected Allspeeds’s Webtool emergency disconnection tools (EDT) for its subsea equipment orientation system (SOES) for installing subsea trees.

As the vessel drifts off-station, the Webtool EDTs that are integrated within the SOES provide quick disconnection of the bundles of hydraulic jumpers and electrical flying leads.

The SOES is deployed on the Skandi Santos subsea equipment support vessel and enables installation of subsea trees in a short amount of time.

In an emergency, the EDT will cut a bundle of 10,000psi hydraulic jumpers linked to the SOES to a subsea tree stack in a single operation.

"The speed and completeness of the cut ensures companies can respond effectively to any emergency."

Allspeeds has supplied four disconnection tools for AKOFS Offshore’s SOES system.

At the time of installation, the hose bundle is manually loaded into the mouth of the EDT and will be retained at the place throughout the life of the SOES.

The hydraulically operated tool has been designed for deployment for extended periods subsea at water depths of 3,000m and can be function tested in-situ.

AKOFS Offshore spokesperson said: "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."

The tool is part of the Webtool range of cutting tools, designed and manufactured by Allspeeds.
