GREAT YARMOUTH, UK – Claxton Engineering Services Ltd., an Acteon company, has developed a new conductor cementing support system (CCSS). Claxton says the new system can save 12 to 18 hours of rig time per conductor waiting for cement to cure.
The Claxton CCSS is designed to secure the conductor with a hydraulic jack-and-clamp mechanism that holds the weight of the conductor while the cement cures. The rig no longer has to hold each conductor, and can move to the next slot and begin running another conductor.
Claxton Technical Director Dannie Claxton says, “The CCSS has a holding capacity of 135–160 tons (123–145 metric tons), and is suitable for conductor diameters of 24 in. to 30 in. However, we can scale the design to any conductor size on request and tailor the footprint and weight handling capacity to specific slot or jacket configurations. The new system has a compact design and can be repositioned easily without a crane. In addition, it offers schedule flexibility because it splits in half, thereby enabling operators to run the conductor before, or after, the CCSS is in place.”
The CCSS has already been used in the field on projects for two major North Sea operators.
