What is the Clamp Installation Tool?The Clamp Installation Tool (CIT) is a diverless, remote-controlled system for installing fittings or clamps on subsea pipelines for repair or to prepare for tie-ins to new pipeline networks. The tool is remotely operated via laptop by an experienced technician onboard a topside diving support vessel or platform.

What makes the CIT so special?When coupled with TDW’s remote-controlled Subsea 1200RC Tapping Machine, the entire subsea process, from clamp installation to hot tapping, can now be performed without diver involvement. Unlike other clamp installation systems, the TDW CIT has the following unique features: topside operated remote-control; can be configured to install any third-party supplied clamp or fitting; continuous real time viewing and monitoring via laptop; passive, remotely-operated vehicle interface makes it easy to operate and minimizes ROV maneuvers.

What is required to use the CIT to install a

fitting or clamp?The CIT is a self-contained tool with a built-in control and hydraulic system. The CIT is a topside-driven machine with a passive Remotely-Operated Vehicle (ROV) interface. The full installation package consists of four basic units: an installation frame that incorporates the installation tool, a control skid, a third party-supplied work class ROV, and a clamp or fitting provided by a third-party supplier.

Is the CIT really faster and more accurate than

other similar systems?Yes. Unlike other remote-controlled CITs, it employs passive ROV interfaces. It also offers more accurate control than other diver-assisted CITs because, as with the Subsea 1200RC Tapping Machine, the technician can actually view and control the installation operation as it takes place subsea, rather than receiving only verbal updates from a diver via radio. This allows for faster and more accurate decision-making as to how the clamp should be manipulated throughout the installation operation.

Does the CIT have applications for

emergency situations?The remotely-operated CIT is ideal for use in emergency situations where pipeline intervention and repair must be carried out in hazardous environments, and concern for safety is particularly high. With its ability to install fittings and clamps of any type, the CIT plays a central role in assisting customers with design and implementation of individual Emergency Pipeline Repair Service (EPRS) programs. EPRS involves preparing emergency repair solutions prior to a failure event.
