Production of the prototype Webtool CRT200 cable recovery tool has been completed and initial testing begun. The YouTube video above shows the tool function test, with the CRT200 capturing and lifting a 7.5” submarine electrical cable.
“We are happy to see the cable recovery tool in action and perform as expected,” says Keith Elliot, engineering director, Allspeeds Ltd. “The cable recovery tool is now scheduled for full qualification testing; once the Webtool CRT200 successfully completes full qualification testing the tool will move on to field trials.”
The CRT200 Cable Retrieval Tool has received design verification approval from international certification body and classification society, DNV GL. It is the first cable and umbilical retrieval tool to meet the exacting design codes and standards for marine operations, and offshore and platform lifting appliances.
The CRT200 cable gripper provides a streamlined cable recovery where the gripper, guided by an ROV, is lowered onto the end of the cable without requiring preliminary clearing of the soil around the cable. The mechanically locked gripping action ensures the umbilical cannot escape during retrieval; moreover, an internal clutch mechanism prevents damage from overtightening. By gripping the end of the cable, it makes subsequent handling much easier, enabling the cable to be recovered to a reeler or spooler on the surface vessel.
The CRT200 cable gripper weighs approx. 600 kg and has a lifting capacity of 20 tonnes. It can be used at any water depth, and is available with hydraulic hotstab or torque bucket interface options.
