The CRT200 Cable Retrieval Tool, developed by Webtool, 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.
Designed to allow the safe and controlled recovery of damaged cable and umbilical, up to 8” (203 mm) diameter, the CRT200 meets the requirements of DNVGL-ST-N001 Marine Operations & Marine Warranty, June 2016 and DNVGL-ST-0378 Standard for Offshore & Platform Lifting Appliances, May 2016.
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.
“Webtool is committed to developing innovative tools for offshore projects,” says Keith Elliot, engineering director, Allspeeds Ltd. “The DNV GL design verification allows us to offer industry-leading engineering to offshore contractors looking for a better way of recovering umbilical and cable from any water depth.”
