MWA Tether Padeye Replacement

RiserTec was involved with the engineering and design of a replacement MWA tether base padeye for a major north sea operator, and the operation of replacing this component in-situ within the riser system at several site locations. The original component had suffered from fatigue damage as predicted in an earlier assessment, requiring a new billet component to be designed and installed. Extensive analysis work was carried out in order to identify the optimum method of replacing this component, before designing and fabricating temporary tether point structures to use in the replacement operation.
