Briggs Marine Contractors will be undertaking subsea power inspections on behalf Scottish Hydro Electric Power Distribution (SHEPD).
The survey, using an ROV launched from the DP2 vessel Glomar Wave, will cover Pentland Firth, mainland Orkney to Graemsay, mainland Orkney to Hoy and Flotta to Hoy.
The inspection operations will start during an appropriate weather window following August 02, 2017 and will continue over a planned minimum period of 10 days, weather permitting.
Inspection will be concentrated across 7 cables. Corridors will be approximately 1km wide based on the centreline defined by the following coordinates.
The ROV will be fitted with video camera, multibeam echo sounder and sub bottom imager and will be launched over the side of the vessel.
During operations, Glomar Wave will be restricted in the ability to manoeuvre. It is requested that all vessels operating within this area maintain a safe distance of 500m and pass at minimum speed to avoid vessel wash effects.
