Allspeeds, manufacturer of Webtool hydraulic cutting systems, has supplied 12 softline cutters to Resolve Marine for a decommissioning project offshore Mumbai.
For the decommissioning project, the Webtool softline cutters will be used to cut 76mm (3 inch) diameter Dyneema softline rope.
The 127mm cutters will be positioned on fibre rope, soft eye slings and activated simultaneously to complete the scuttling of a rig jacket leg.
During decommissioning, the jacket leg is lifted by a barge via 12 chain tensioners attached to the softlines. The jacket is then suspended horizontally with the softline slings arranged in two groups of six along two of the jacket’s four legs.
The Webtool cutters are designed to be attached to the softlines either subsea or topside on the vessel. Once the jacket leg is moved into place, the softlines will be cut simultaneously, powered by a diesel powered, hydraulic power pack on the salvage vessel.
