James Fisher Subtech (JF Subtech), provider of specialist technical marine support to the renewables, oil and gas, civil works and salvage markets, and part of James Fisher and Sons plc, has successfully completed a challenging subsea inspection, repair and maintenance project for Ithaca Energy on its Floating Production Facility, the FPF-1, situated approximately 280 km East-Southeast of Aberdeen.

The project, which was prepared for at short notice and partially conducted during the FPF-1 shutdown period, saw JF Subtech achieve incident free operations with a 99% equipment operational uptime rate. Its completion marks a milestone for JF Subtech as the first project completed following a rebrand in March 2021, through which the group consolidated its core competencies to provide offshore operators with expertise for the extremes.

Utilising a mix of Air Diving and ROV techniques, JF Subtech undertook the installation and removal of cofferdams to facilitate internal valve maintenance, carried out rectification on riser guides and completed essential inspection work on over 160 areas of the FPF-1 hulls and sub-structure.

Despite having to contend with short workable weather windows, the team on board the Olympic Challenger, a DP2 construction vessel equipped with a JF Subtech Air Dive Spread and Cougar Light Work Class ROV system, were able to execute 80 air dives and 126 hours of ROV operations.

John Ewen, assets and operations director at JF Subtech, said: “The scope of work that Ithaca Energy brought to us was a challenging one, but thanks to our experience in supporting operators in extreme environments, we were able to execute the work safely and to the tight deadlines required.”
