GREAT YARMOUTH, UK – Claxton, an Acteon company, has installed a fully forged high-pressure drilling riser system as part of a contract for the Catcher area field development in the central North Sea. Each joint was forged from a single billet of material with no joining welds, said Claxton.
Claxton’s scope of work includes the subsea connector to latch the riser with the subsea wellhead; riser tensioning interface from the riser to the rig’s tension system; all riser handling tools and a suite of custom-designed bolt tensioners to facilitate flange make-up.
Acteon sister company, 2H Offshore, provided the riser analysis for the Catcher development.
Claxton secured the contract last year and began mobilization this past July. The contract is for three-and-a-half years, with a possible extension.
The system was installed for Premier Oil’s Catcher area field development, which includes the development of the Catcher, Varadero, and Burgman fields in block 28/09a in the UK North Sea.
