FPSO Ballast Tank ACFM ROV Inspections

Geo Oceans and Vertech, in collaboration with TSC, used mini ROV systems, specialised actuator systems and ACFM equipment to measures and map crack indications in water ballast tanks owned and operated by one of Australia’s largest oil and gas operators.

Prior to mobilisation a desktop 3D modelling assessment was performed to confirm ROV and tooling access to all anomalies, and to facilitate tooling design modifications.

Five ballast tanks were surveyed during the campaign with the ROVs operated from a workshop module on the FPSO up to 150m away from the tank entry. All surfaces were cleaned with the ROV using mechanical cleaning tools before being inspected with ACFM. In addition, a close visual inspection of each tank was performed using high definition video cameras streamed live to the inspector and attending Lloyds Register surveyor.
