Hydraulic cutters and systems specialist Allspeeds, the designers and manufacturers of Webtool, has announced a compact ROV cut loop cutter for emergency activation of a Blow Out Preventer (BOP). The Webtool cut loop cutter will sever the cutting loop to activate the BOP in the event other measures have failed.

Subsea intervention involves the use of remotely operated tools that often include cut loops as a redundancy measure to prevent a blow out once all ‘topside’ solutions have failed to work. The cut loop prevents pressure lock in the hydraulic system needed to activate the BOP.

During intervention, the Webtool cutter is held in position over the cut loop by an ROV in case of an emergency situation. The wide mouth, open sided design of the Webtool cutter allows for easy positioning of the tool on the stainless steel, hydraulic cut loop pipe. The specially designed blade has been developed to ensure the cut loop will always fully release pressure immediately after the cutter is activated.

This is Webtool’s smallest hydraulic guillotine cutter so far, making it ideal for operation in confined spaces. It has a corrosion resistant stainless steel body and cylinder. The blade design is optimised for cutting stainless steel tube. Long blade and anvil life ensures that tool maintenance is kept to a minimum.

The Webtool cutter can be used at any water depth, with pressure compensation on the hydraulic supply. Weighing 7kg in water, the cutter uses 700bar maximum input pressure. An optional hydraulic intensifier is available.

Webtool cut loop cutter is part of the Webtool range of high performance hydraulic cutters and systems, designed and manufactured exclusively by Allspeeds Ltd in the UK.
