RetroClamp™
Subsea clamping system for tubulars and pipelines

Clamps are easily customized to fit any diameter from 4” through 60”.

Designs are available to fit most structural shapes and configurations including, plate or beam edge, square tubing etc.

Anti-Snag designs are available in areas with extensive fishing activity (pictures on opposite page). Various contact tips are available to accommodate a variety of situations:

Standard Pointed Tip – Use on structural or non stressed areas where a small indentation is not a problem.

Slotted Volcano Tip – Use on pressurized structures or pipelines with thin film coatings, or where coating removal is anticipated.

Masonry Cutting Tip – Use to cut through concrete weight coatings with RetroReader, to verify connection.

Drift Awl Tip – Use for thick film multi-layered coatings or thermally insulating elastomeric or syntactic coatings (also for use with the RetroReader). Isolated Plug

Sample RetroClamp Configurations

Permanent Monitoring - This double-clamp is used to mount long-term monitoring instruments (DR-2 dual reference electrode shown) as a part of a larger monitoring system, or to mount spot anodes to bottom-laid or buried pipelines. Double clamps provide a reliable and redundant pipe connection system.	ROV Clamp - This is the “standard” RetroClamp, fitted with a fish-tail handle for the ROV to manipulate. Connection cables not shown. RetroClamp can be connected to any form of anode sled (RetroPod and RetroClamp pictured below)	SmartClamp - The SmartClamp is a self contained CP monitoring test station for underwater pipelines. The RetroClamp is fitted with a V-String zinc reference electrode, as well as a SunStation readout. Easily ROV-installed on any tubular or flowline, the SmartClamp provides CP readings to the ROV, which interrogates it.
With V-String - The RetroClamp shown here is fitted with a V-String zinc reference electrode, which is to be hard-wired to the surface as part of a permanent monitoring system on an offshore platform, to be interrogated from the surface.	Diver Clamp - Fitted with a T-Handle (shown) or a standard hex head, the RetroClamp is easily applied by divers to platform members or pipelines to replace sacrificial anode material. Once attached to the member, the diver rotates the T-Handle until electrical contact is made. Connection cable is not shown.
