Wind Farm Monopile Weld Integrity Study

One of Film-Ocean’s existing customers who specialised in offering advanced NDT inspections had
a requirement to deploy tooling to inspect the circumferential welds in offshore wind farm
monopiles. The project required an ROV to interface a phased arranged automated ultrasonic tool
and deploy to the worksite. The tool developed should be standalone.
To avoid the high sub surface current and bad
visibility Film-Ocean proposed to deploy
equipment inside the monopile where the
environmental conditions were not affected by
external environmental conditions.
• A hydrostatic suction system was developed and
integrated into one of Film-Ocean’s inspection
class ROV’s to aid station keeping whilst the
automated NDT was ongoing.
• Weight saving methods were used on the ROV
and tooling. Project specific buoyancy was
designed and integrated into the system to allow
for ease of operations.
