Faster, safer, better: Claxton leads the way in drilling riser handling tools
MAKING LIGHT WORK OF MULTI-STUD TENSIONING
The Claxton multi-stud tensioning (MST) system delivers significant time savings when compared with conventional torqueing methods. On a 24-in. riser, for example, the traditional approach involves individually tightening the bolts, a process that could take 3–4 hours. The MST system cuts make-up time on the same joint to just 20–30 minutes.
Critically, the MST system also helps to ensure that the bolts are tensioned by the same amount and to eliminate the variation that often occurs during traditional tensioning methods. Bringing the flange faces together uniformly by tensioning the bolting simultaneously results in better gasket alignment during make-up and, thus, reduces the risk of twisting or crushing the gasket. The hands-off approach enabled by Claxton’s MST equipment reduces the requirement to lift heavy torque equipment during installation; the traditional approach involves moving heavy tooling round the flange and onto the individual nuts to complete the connection.
A DIFFERENT APPROACH TO GASKET HANDLING
While supporting a major offshore development project, Claxton was asked to develop a special gasket-handling tool that could meet a specific client request and facilitate handling in a tight and sensitive location. The Claxton tool links into the internal wall of the gasket and provides mechanical lift. This removed the need for manual handling and minimised the potential risk of damage to the gasket and sealing faces of the riser/flange.
The safe and efficient handling of riser systems is a crucial aspect of offshore operations. Applying the most effective tools and techniques to managing these vital pieces of equipment can deliver significant advantages in terms of safety, scheduling and reduced project costs.
UNRIVALLED DRILLING RISER CAPABILITY
Claxton’s riser delivery capability extends to more pressure, connector, tensioning, tooling and complete system configurations than any other supplier – our riser will be genuinely optimised to suit every nuance of your drilling campaign. When you need a riser, trust Claxton to make it happen.
