A guide to innovations in high pressure drilling riser technology
WORLD’S HIGHEST-PRESSURE 18.3/4” DRILLING RISER
Together with Acteon Group sister companies 2H Offshore and Subsea Riser Products, Claxton provided an ultra-high-pressure riser for use during high pressure, high-temperature drilling campaign.
The unique design became the world’s first full-bore access riser capable of working at pressures in excess of 12,000 psi.
INNOVATIVE TENSION RINGS
Claxton designed the first-ever positive grip tension ring which has since been emulated by many. Since then, Claxton has continued to improve the design and we now have multiple types of tension ring for various applications – all are completely reusable and transferable from well to well.
The slimline version of the slip activated tension ring eliminates space-out issues and can be positioned at any point, and used from well to well.
The innovative design provides an even simpler installation due to its use of just four anchor bolts. The slip segments are free-floating within the tension ring body housing. Slip inserts enable the tension ring to have its inside diameter reduced to suit varying riser sizes.
Gecko Grip tension ring
The next generation of tensioning technology – the Gecko Grip tension ring uses an abrasive grit instead of ‘teeth’. The ring is designed for use in production applications or longer application times and in areas where there are specific concerns regarding fatigue life and stress concentrations.
