Product or Service

Riser analysis and engineering of a riser to allow it to perform optimally and safely against the subsequent results are essential to provide a fit-for-purpose drilling riser system.  

Claxton provides a comprehensive drilling riser analysis service and design consultation that draws on extensive in-field riser experience for optimum performance during drilling, workover or decommissioning operations. 

Claxton’s riser inventory, which includes one of the largest stocks of riser spools and joints in Europe, means we can quickly tailor a system to analyse results and meet the needs of clients drilling campaigns. 

Our riser analysis engineers routinely work with other specialist companies in the Acteon group, including 2H Offshore and SRP, to engineer bespoke solutions. Collectively, we have delivered world-class 12,200psi technology and regularly leverage our combined experience to provide seamless solutions to any issues posed by the analysis results.
