Abstract

The project encountered several problems. In the first place COVID restrictions and procurement issues delayed the build of the sensors, delaying the deployment until the end of the summer (August 2021) rather than spring as intended. Following on from this, travel restrictions, both government imposed and company policy concerning COVID prevented anyone from Chelsea Technologies from visiting the host at any stage in the process.

The second problem was only realised towards the end of the deployment. The sensor stopped responding at the end of November. The next available window to raise the subsea frame coincided with the end of the deployment so it was not possible to fix or replace the sensor. On raising the sensor and the control housing it became apparent that significant corrosion had occurred around the windows, raising severe doubts about the validity of the collected data.
