Following a discussion and technical review of a customers preferred usage pattern, the CRT200 has been redesigned to allow subsea deployment for periods of up to 20 days. Improvements to the applied coating systems will allow the tool to better inhibit corrosion and allow for the longer deployment. The customer explained the operational and financial advantages of using a smaller, cheaper vessel to deploy the gripper. They would then return days later with the larger, more costly winch vessel to perform the retrieval operation over a shorter duration.
Designed to allow the safe and controlled recovery of damaged cable and umbilical, up from 152mm (6”) to 205 mm (8”) diameter, 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. 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 maximum load capacity of 20 tonnes. It is operable via a standard class 4 torque tool.
“With the growing need to ensure offshore subsea operations are both cost-efficient and sustainable, the ability to deploy and abandon the CRT200 Cable Gripper for up to 20 days before recovery to the surface is a significant boost to the gripper’s utilisation in cable and umbilical recovery campaigns,” says Keith Elliot, managing director, Allspeeds.
Only DNV Approved Cable Recovery Tool
Developed in consultation with international certification body and classification society, DNV GL, the CRT200 Cable Retrieval Tool is the only cable and umbilical retrieval tool to meet the exacting design codes and standards for marine operations, and offshore and platform lifting appliances. Specifically, the CRT200 satisfies 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 Webtool CRT200 Cable Retrieval Tool is designed and manufactured in the UK exclusively by Allspeeds Ltd.
