Case Study

With an ageing North Sea asset requiring its final annual subsea inspection campaign prior to decommissioning, ROVOP was called upon to provide a bespoke solution.

The answer was to mobilise a Seaeye Panther XT+ 950 mid-size ROV to the floating production vessel. The 14-slot subsea template at 140 MSW was inspected, along with the vessel’s hulls, flowlines, umbilicals and risers. A series of CVI, GVI and CP techniques were used.

ROVOP also coordinated operations closely with a third-party contractor for anchor cleaning and measurement operations, while photogrammetry operations were also conducted to assist with the removal planning process.

Due to Covid-19 restrictions, accommodation onboard the FPV was limited. ROVOP successfully navigated this obstacle through live audiovisual streaming, with ROVOP staff onshore in Aberdeen remotely managing the inspection campaign – thus reducing the offshore headcount by three persons.
