Tensioning of risers & conductors
Critical systems for offshore drilling
Riser and conductor tensioning systems are critical in offshore drilling operations. Claxton’s solutions offer reassurance and add value, leaving nothing to chance.
The tensioning systems apply a pre-calculated load to provide rigidity to the riser or conductor during drilling operations and reduce the applied axial loading from the blowout preventer (BOP) stack and well control equipment.

RISER TENSION SYSTEM INNOVATION REDUCES RISER FATIGUE
BG Group plc approached Claxton to provide a conductor tensioning system to meet some unusually demanding requirements. The company wanted to drill in water depths of 78 m in the Jackdaw field using the Rowan Gorilla VI jack-up drilling rig – nothing too out of the ordinary so far. However, as Chris Kyson, project engineering team leader, explains, “A combination of the way the rig was configured, the environmental conditions in the area and the fact that BG Group wanted the system to be capable of withstanding the sort of seas normally associated with a 50-year storm, resulted in the need for a conductor tensioning system that could generate up to 400 tonnes of load.”
