Marine Warranty
Trusted by our clients, and with an extensive track record in delivery of complex rig move operations, ocean tows, casualty response and decommissioning projects, our ‘hands-on’ expertise makes Interocean uniquely placed to provide expert Marine Warranty Services (MWS) across a range of marine projects.
Our expertise is focussed on the following key areas of activity:
- Mobile offshore drilling units – MWS for rig moves (including location approvals), ocean tows and dry tows.
- Offshore Construction projects – MWS for critical operations; FPSO moorings and hook-up and decommissioning activities.
- Marine Transportation – MWS for towage, vessel and barge suitability, loadouts (incl. heavy lifts), cargo stowage and seafastening.
Recognised for their capacity for direct responsibility and accountability, our Marine Warranty Surveyors provide independent third-party review and on-site approval of high risk / high exposure marine projects. They provide a critical function in ensuring that risk is identified, controlled and minimised at all stages by ensuring the operation is a) planned in accordance with relevant industry codes and standards, b)executed in accordance with the agreed procedures and safety constraints and c) utilises project equipment and project vessels which are suitable for the operation.
Working as an integrated team, our qualified and experienced Master Mariners, Naval Architects and Engineers combine their extensive operational and technical skills with knowledge of risk and regulatory compliance to enable us to provide tailored and effective MWS.
Interocean has no conflicting interests. We are completely independent of any regulatory authority, rig or vessel owner or contractor. Interocean is approved as a provider of Marine Warranty Services by a number of leading underwriters and also act as MWS on behalf of self-insured clients.
