Asset-based ROVs help James Fisher minimise downtimeProjects and Operations // November 9, 2016
James Fisher Subsea (JF Subsea) says it has reduced inspection downtime to 2 per cent for Shell UK through the innovative use of asset-based remotely operated vehicles (AB ROVs) on oil rig inspection programmes in the North Sea.
Traditionally, oil rig inspections are undertaken using a dedicated remotely operated vehicle support vessel (ROV SV), on which an ROV is secured. To remove the need of a ROV SV and the hazards involved with securing an ROV to the offshore platform, JF Subsea provided Shell UK with a gravity-based AB ROV system.
While the use of AB ROVs is not a new concept, the innovative way in which JF Subsea adapted them to Shell’s needs, and the duration for which they were utilised, demonstrates the close working relationship the company develops with its customers as well as its ability to tailor services to specific requirements. Following focused engagement sessions between both companies’ offshore installation managers, AB ROV’s were successfully trialled on a planned riser and structural inspection on Shell’s Brent Bravo platform in the North Sea.
JF Subsea - which has a strongly developed relationship with Shell - provided inspection equipment, ROVs and personnel as part of a bespoke turnkey solution, with the inspection completed and a final report delivered within two weeks. Post project analysis concluded that downtime was reduced to 2 per cent over the four month campaign period.
Tim Welford, operations manager at JF Subsea said: “We have long project managed and supplied inspection solutions to Shell UK within the North Sea, and our latest collaboration has not only delivered the exceptional service Shell have come to expect, it has also improved efficiencies from all angles and provided detailed, credible reporting. Following the success of the 2016 AB ROV inspection campaign on the Brent Bravo, Shearwater, Curlew, Brent Alpha, Gannet and Nelson platforms, Shell UK are now in discussions with JF Subsea to supply this style of service for the next five years on various platforms in the North Sea. JF Subsea is actively marketing this service globally as the benefits cannot be dismissed."
