UWILD, managing marine assets, reducing HSE risk and deliver cost-savings

Share

UWILD (underwater inspection in lieu of drydock) inspections are a recognised maritime service carried out to ensure the structural and operational integrity of the marine assets and ensure a vessel’s seaworthiness during its operational lifespan and adherence to statutory legislation.

Dry-docking an FPSO is costly, it takes the FPSO out of service incurring a loss in production revenue as well as the significant costs associated with disconnecting and reconnecting the FPSO.

UWILD inspections are performed on location and are a cost-effective and time-efficient method for carrying out necessary annual hull and mooring inspections. Inspections can highlight repair areas before drydocking, reducing drydocking time and enabling the ship to resume operational service earlier than having an inspection conducted during drydocking.

As an accepted alternative to drydocking inspection surveys, UWILD presents a faster, safer and more cost-effective solution for conducting hull, sea-chest and overboard discharge cleaning, and thruster, valve and weld inspections also mooring chain measuring with Film-Ocean’s patented Chain Measurement tool.

Cost savings and time efficiencies are achieved by eliminating any costs associated with the removal and reinstatement of the FPSO, coupled with no loss in production revenue.
