Notice to Mariners Scottish Hydro Electric Power Distribution (SHEPD) – Notice to Mariners October 2018
Issued: 4th October 2018
Please be advised that Global Marine (on behalf of SHEPD) will be undertaking inspection work related to submarine electricity cables as noted below:
• Clift Sound
• Papa Stour – Mainland Shetland
• Shetland – West Linga
• Shetland – Whalsay
• West Linga – Whalsay
• Whalsay – Outer Skerries
• Yell – Fetlar 2
The purpose of the work is to confirm the exact location and condition of the cables. This will inform SHEPD’s schedule for replacing cables over the coming years. The inspection will utilise two different vessels:
▪ Global Symphony ▪ MPC Advance
The operations will commence during an appropriate weather window following 15 October and will continue over a planned minimum period of 2 weeks, weather permitting. These timescales are dependent on weather conditions and the granting of necessary licences from Marine Scotland.
The operations will be concentrated across the cable corridor shown on the following charts:

Works Description
The inspections will involve the use of a Remotely Operated Vehicle (ROV) equipped with a full suite of geophysical survey systems (Multi beam Echo Sounder and Side Scan Sonar). The ROV will be operating close to the seabed, at a distance from the vessel (potentially 20m from the MPC Advance and potentially 100m from the Symphony).
The ROV will be towed behind the vessel, and will operate within 1-3m of the seabed, and cable. The ROV will work along the route of the cable. In the water between the ROV and the vessel there will be the umbilical of the ROV – the exclusion zone mentioned below is to ensure passing vessels do not pass between the ROV and the vessel which would risk snagging the equipment, particularly the umbilical.
The programme for the works is subject to significant change. The list of cables at the start of this notice is shown in planned sequence, starting on 15 October and spending approximately 2 days per cable. However, this is subject to change.
Other vessels should maintain an appropriate and safe distance of 500 m when passing the inspection vessel(s) whilst undertaking operations and should pass at the lowest possible speed to avoid vessel wash effects. The vessels will be working up to 24 hours per day and will display appropriate day shapes and lights during reduced visibility and night operations. The vessel(s) will also monitor VHF Channels 16 and 12.
