BMT has announced a partnership with Sonardyne to deliver to Subsea 7 its ‘Riser Monitoring System’ (RMS). This subsea integrity monitoring solution has been adopted by the world’s largest spar platform, Aasta Hansteen. The Aasta Hansteen spar platform is operated and owned by Equinor ASA, the Norwegian multinational energy company.

Located 300 km west of Sandnessjøen on the Norwegian Continental Shelf (NCS) in water depths of up to 1,300m, the deepest field development on the NCS, the Aasta Hansteen spar is installed in a harsh environment utilising highly robust deepwater steel catenary risers (SCR).

Neil Charles, Operations Director for offshore at BMT North America commented: “With the installation of SCRs, advanced sensing technologies for use in offshore oil and gas applications, this new RMS will greatly assist the Aasta Hansteen spar platform with precision planning of maintenance activities and deliver real potential for safe asset life extension. It combines rapid data processing and high-fidelity output with proven analysis expertise, to offer our client’s float-on operation a leading-edge solution to integrity management and drives our innovation in this field.”

The BMT integrated RMS includes a suite of strain, motion and position sensors deployed by underwater remotely operated vehicles (ROVs) to monitor the SCR response in the touch down zone (TDZ) and riser interaction with the spar floating production storage and offloading pull tube. The computationally intensive data collated by the RMS is used to validate and bring efficiencies to the spar and SCR design.

BMT and its industry partner Sonardyne will be at OTC between 6-9 May 2019. Visit them at booth 1439-J in the EIC UK Pavilion in NRG Park, Houston, Texas.
