Tie-Back Clamping System for Subsea Cathodic Protection Systems
in conjunction with Deepwater Corrosion Inc.

Product Overview

RetroClamp provides fast reliable electro-mechanical tieback for subsea cathodic protection systems. Originally designed for pipeline CP retrofit applications, the RetroClamp is now widely used in a variety of subsea retrofit projects. The standard RetroClamp for tubulars is pictured above.

Please also see RetroClamp CP, a modified version of RetroClamp which facilitates the attachement of anodes directly to the clamp.

Deepwater Corrosion Services is a recognized leader in offshore cathodic protection retrofit innovation. Hundreds of RetroClamp clamps are now in service in the Gulf of Mexico, and many have been installed by ROV. The installation efficiency of the RetroClamp has saved customers hundreds of thousands of dollars. Successive iterations have significantly improved the product.

RetroClamp is also routinely customized for application to wellheads, vessels, and large-diameter members. It has been modified to allow subsea attachment of a wide variety of equipment, including cable runs and monitoring instruments. The customized wellhead RetroClamp pictured to the right facilitates rapid attachment to a subsea pipe flange via a diver or ROV.

Main Benefits

• Rapid installation even over concrete weight coatings.

• Constant tension provides long-term reliability through vibration or thermal expansions.
• Hollow ground tip contact (for pipelines) eliminates stress-raisers and replaces expensive friction welding.
• Conventional cone tip available for structural connections.
• Open-base design ensures clamp will pull loose if snagged, preventing any damage to pipeline.
• Easily handled by ROV’s.
• Available in sizes from 4” to 60”.
• Most sizes in stock for immediate delivery.
