Hydraulic systems specialist Webtool has introduced a new gripping and lifting tool for recovering subsea umbilical and cable for offshore oil and gas and decommissioning projects. The Cable Retrieval Tool (CRT200), developed in consultation with international certification body and classification society, DNVGL, allows the safe and controlled recovery of damaged cable and umbilical, up to 8” (203 mm) diameter.
Current methods of recovering umbilicals for repair or replacement involve trenching the seabed around the cable or umbilical to allow a double choke sling to be attached using an ROV. The hydraulically operated Webtool CRT200 gripper aims to offer a quicker and safer method of retrieval and improved handling, according to the manufacturer.
The CRT200 cable gripper provides a streamlined cable recovery whereby 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.
