Presented on Wednesday 18 May: Session 10 Between May and November 2021, Woodside, in collaboration with Fugro, completed multiple, world-first, fully uncrewed inspection campaigns of trunklines and subsea infrastructure in the North West Shelf, all utilising a surface vessel and underwater robot (ROV), remotely operated via beyond-line-of-sight satellite communications architecture. Similar work is traditionally performed by a Multipurpose Support Vessel (MPSV) with >50 people onboard, consuming >20 m3/day fuel during transits. Transition to uncrewed remote operations technology has enabled the use of a much smaller (12 m) vessel, removing health and safety risk associated with offshore crew, and with <0.2 m3/day fuel consumption during transit. High-resolution hull and ROV-mounted multi-beam data, ROV-mounted laser point cloud data, ultra-high-definition images and videos and Cathodic Protection (CP) field gradient data were all successfully collected, and operations were completed from the busy Dampier Port with no incidents. Delivery of this landmark achievement was enabled by a multi-year staged technology plan in collaboration with Woodside’s subsea Inspection, Maintenance and Repair (IMR) contractor, Fugro, including establishment of a dedicated remote operations centre based at International Communications Facility. Extensive stakeholder engagement was performed internally and with external regulatory bodies to ensure that all risks were captured, understood and managed so that all parties were aligned on implementation of the novel approach. Application of this technology is forecast to transform the costs of IMR operations vs traditional methods, effectively eliminate carbon emissions and offshore personnel exposure hours, and create opportunities for a more diverse workforce in the sector.
