Global subsea equipment solutions specialist Ashtead Technology has successfully completed a subsea installation monitoring project for Ocean Installer AS in Equinor’s Askeladd and Johan Castberg fields. The contract saw Ashtead Technology provide its integrated Deflection Monitoring System services and equipment to support the installation of eight Integrated Template Structures in the fields located in the Northern Norwegian Sea. During operations, the dual independent DMS systems monitored, calculated, displayed and logged structure deflection, heading, pitch, roll, depth and suction can differential pressures, in real-time. This method of real-time monitoring is vital during the placement of suction can based subsea structures as it ensures any potential issues can be anticipated without delay, reducing the risk of structural damage.

The scope of work took place in quick succession over a 25-day period. This saw the project completed well ahead of schedule and resulting in significant cost efficiencies.

During the placement of the structures, the DMS systems were configured for autonomous independent operation, communicating data to one of the installation ROVs. Ashtead Technology utilised a range of measurement sensors and positioning tools along with special techniques to enhance the accuracy of the data collected, ensuring maximum performance of the system.
