Subsea installation monitoring

Ashtead Technology was contracted by i-Tech Services on behalf of Subsea 7 to deliver installation monitoring services in support of Equinor’s Utgard development, located in blocks 15/8 (NCS) and 16/18a (UKCS) of the central North Sea.


Ashtead’s Deflection Monitoring System (DMS) was used to capture critical data required to safely deploy a subsea template in water depths of 110m from Subsea 7’s vessel, the Seven Arctic. The DMS monitored structure deflection, heading, pitch, roll, depth and suction at differential pressures, in real-time.

Benefits delivered

Ashtead Technology utilised a range of measurement sensors and positioning tools to enhance the accuracy of the data collected, ensuring maximum performance of the system. The DMS minimised the risk of structural damage throughout the installation and allowed informed decisions to be made during critical operations, ensuring safety requirements were met.
