James Fisher Subtech (JF Subtech), provider of specialist technical offshore solutions and part of James Fisher and Sons plc, has successfully completed a subsea inspection, repair and maintenance (IRM) contract for NEO Energy – one of the leading North Sea oil and gas producers – on its floating production storage and offloading (FPSO) vessel, Global Producer III (GPIII), located in the Balloch field, Central North Sea.

The contract saw the safe and efficient execution of the FPSO’s IRM scope and required JF Subtech to apply its comprehensive experience of technically complex project scopes in harsh environments, utilising its air diving and ROV expertise to undertake the operation on the GPIII vessel’s hull, in accordance with NEO Energy’s asset integrity program.

JF Subtech helped ensure the FPSO’s thruster system’s continued operational capability and high performance to preserve the critical requirements of safety and stability around the GPIII’s turret mooring system during ongoing production activities, within the harsh North Sea environment conditions.

Following the fast-tracked development of project specific procedures by the project delivery team, JF Subtech moved swiftly to charter the offshore construction vessel Olympic Challenger and mobilise a team of 35 offshore personnel to safely execute the scope of work. Navigating the short turnaround window, JF Subtech’s significant air diving experience allowed for safe and efficient completion of the project within budget.

The scope of work included the removal of an existing thruster by lowering it through the GPIII hull, followed by subsea transfer and recovery to the deck of the diving support vessel (DSV), with the reverse process being implemented to install the replacement unit. The works program also included the inspection and replacement of the starboard forward linear loop anode and reference electrode, part of the vessel’s impressed current cathodic protection system.

Giovanni Corbetta, Managing Director at JF Subtech, comments, “We’re delighted to have delivered such a successful first project with NEO Energy. Even when executing the work in a short preparation window, we were able to adapt quickly to secure the necessary equipment and bring in our trusted diving team who ensured that we were able to complete the project to a high standard and remain incident free.”

Due to the success of the project, JF Subtech has recently signed an additional air diving contract with NEO Energy to carry out further work with NEO Energy on the GPIII vessel, expected to commence later this year.
