Stability monitoring systems

Ashtead Technology was contracted by a leading subsea engineering and construction firm to design and supply instrumentation packages to monitor submerged buoys for heading, pitch, roll and depth. The buoys supported 27 steel catenary risers


We deployed our stability monitoring system, which consisted of an instrumentation package installed and operated by ROV. Subsea system data was transmitted to a topside vessel via an acoustic modem and cable. Extended autonomy was achieved with power management and optimisation.

Benefits delivered

The stability monitoring system provided essential data during critical stages of the first ever installation of the buoyancy module and SCRs’. Our system performed faultlessly throughout the project, delivering valuable data for the successful installation of the buoys and SCRs’.
