Currently in use by two major North Sea operators, Claxton’s conductor cementing support system (CCSS) negates the need for the drilling rig to wait on cement when batch-setting well conductors – saving anything from 12 to 18 hours per installation operation.

Recently it has become increasingly common for operators to install conductors through their jacket structure, prior to installing platform topsides.

While this practice offers a host of scheduling benefits for the operator already, Claxton’s engineers have worked to offer operators a way to further enhance their conductor installation operations – creating a unique supporting system that holds the conductor while cement cures, enabling the rig to move on and install another conductor.

Naturally, when installing multiple conductors the cost savings involved become extremely attractive.

YOUR PROJECT IS UNIQUE, SO WHY ISN’T YOUR TOOLING?

Built to order, the system is completely tailored to your platform deck and project specification – something our in-house design team can do with ease.

The system is currently rated to hold 135 to 160 tonnes and 24” to 30” OD conductor, however, the design can scale to virtually any size on request.

OPERATIONAL FLEXIBILITY – ASSURED

We’ve worked to ensure the Conductor cementing support system offers maximum operational flexibility for operators. For instance, space is always at a premium offshore – so the CCSS is designed so the jacking element can be deployed and retrieved through the rig’s diverter housing (49.5″ diameter ID housing).

Thanks to a compact design, the system uses heavy-duty castors and does not require the use of a crane or rig to reposition within the well bay/platform structure.

The system can be split in half, giving you flexibility on whether you run the conductor before or after the system has been put in place.
