Structural Analysis of Captain FPSO Lower Fairleads

Structural Analysis of Captain FPSO Lower Fairleads

During a routine inspection on the Chevron operated Captain FPSO (floating production, storage and offloading vessel) the company identified an integrity issue with one of the vessels eight fairleads – noting that one of the bolts connecting the gypsy wheel shaft to the skirt of the fairlead was missing. This identification reinforces the importance of Chevron’s rigorous maintenance, reliability and integrity procedures. IDAC carried out a number of structural analyses on the Fairlead design, to investigate the cause of a failure in the bolts and to evaluate the work that would be required to prolong the life of the Captain FPSO Fairleads.
