LONDONBMT has teamed up with Sonardyne to supply its riser monitoring system (RMS) to Subsea 7 for use on the Aasta Hansteen field spar platform in the Norwegian Sea.

The platform, operated by Equinor, is moored 300 km (186 mi) west of Sandnessjøen in a water depth close to 1,300 m (4,265 ft).

It is also the first platform in Norwegian waters to be connected to steel catenary risers (SCRs).

Neil Charles, operations director for Offshore at BMT North America said: “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…”

The system incorporates various strain, motion, and position sensors deployed by ROVs to monitor the SCR response in the touch down zone and riser interaction with the spar FPSO pull tube.

Data collected by the RMS is used to validate and bring efficiencies to the spar and SCR design.

Sonardyne provided an innovative underwater acoustic positioning system to support the subsea riser monitoring.

At OTC, BMT and Sonardyne are exhibiting at booth #1439-J in the EIC UK Pavilion.
