Samphire provided subsea IRM and marine activities support to a small operator in the summer of 2014.
A major activity being supported was the repair of the FPSO mooring system. This involved carrying out replacement / repair on two mooring lines. It was a complex activity involving air diving from a daughter craft and mother vessel, along with an anchor handler vessel for mooring line recovery / deployment and ROV support, and a heading control tug. The challenges included weather sensitivity, POB limitations on the FPSO, and SimOps with FPSO shutdown work.
Other support included extensive interface with a third party subsea field operator, where it was required to approve vessel entry to FPSO or subsea 500m zones from a Duty Holder perspective.
In addition, a turret bearing inspection workscope was developed and executed offshore as part of the FPSO integrity scheme.
Advice was also provided to the development of SMSIDs for various third party subsea activities.
