500 IMR days

As a ‘subsea janitor’, work under water includes to observe and report the technical integrity status of subsea facilities, early detection of faults, followed by adjustments and potential repair, due to wear and tear or accidental impacts. The IMR activities arise from a planned inspection and maintenance scheme authored by the field operator, and can both include initiatives to improve the production, or on the opposite, engage activities to terminate production. IMR is one of Reach Subsea’s core business segments, and our vessel fleet includes specially equipped vessels for this purpose, typically Havila Subsea and Topaz Tiamat. Both vessels have sufficient deck load capacity, offshore crane and 2 work class ROV’s in addition to a high accuracy subsea positioning system and the offshore project team, together defined as ‘the Vessel Spread’.

Reach Subsea holds several IMR Frame Agreements with BP, BHP, Shell, Wintershall Dea and Equinor, for the supply of Subsea IMR Services internationally and on the Norwegian Continental Shelf. The work awarded, often consists of smaller work tasks on various subsea facilities, bundled into campaigns to ensure high utilization of the Vessel Spread.

IMR work require detailed engineering and planning, not only to ensure the correct method and tool is mobilized for the right subsea task, but also to ensure efficient logistics and quality of subcontractor services. Reach Subsea utilize 3D vessel models and digital planning tools in addition to extensive practical experience, when planning IMR campaigns on behalf of our Clients. Efficiency in operations is highly dependent on the experience of the operator and the offshore project team. Over the years, Reach Subsea have attracted both graduates and experienced personnel, merging a valuable combination of new technology and experience when solving the subsea puzzle of various challenges. Detailed task plans are required, subject to Safe Job Analysis and verification by the Client to ensure all considerations have been taken into account.

An IMR campaign typically include an offshore project team managed by an Offshore Manager, supported by Shift Supervisors, work class ROV teams and a deck crew. The Vessel’s back deck is furnished with the subsea tools and equipment, sea fastened and positioned according to engeered calculations and plans. In addition to the standard instrumentation, the ROV’s are typically equipped
with hydraulic or electric torque tool to allow for operation of valves. The subsea positioning systems require digital maps of the specific subsea fields, to allow for correct positioning of vessel and ROV.
Reach Subsea have successfully performed 500 IMR days, and we are proud to say this has been accomplished without any major accidents or incidents. We believe our HSE culture is a result of experience and learning from the past, and as we move forward – our dedication to perform safe & efficient IMR operations will remain unaltered.
