RetroClamp can be installed by diver or ROV, with contact tips capable of safely penetrating pipeline coatings.
The Retroclamp was originally designed to facilitate ROV attachment of retrofitted cathodic protection anode sleds to offshore pipelines. The first clamps were built and deployed in 2000, and since that time, the clamp has been adapted and improved significantly for strength and versatility. Thousands of RetroClamps have been successfully installed by divers and ROVs for a wide variety of applications, including attachment to wellheads, vessels and large-diameter tubular members.
The simple push-and-twist installation means that the clamp is usually installed in minutes; the unique design of the spring-tensioned floating plate ensures that the low-resistance electrical contact is maintained under constant tension. The clamp can be configured with a range of contact tips that allow it to be attached without cleaning or coatings removal in most cases. Even concrete weight coatings can be penetrated, saving a significant amount of time and effort during installation.
