Show MoreShetland HVDC Cable Project
Scottish Hydro Electric Transmission Plc, are installing the Shetland HVDC Link cable for Campaign 2. Campaign 2 begins from Weisdale Voe, Shetland, KP0 to KP62.
The Shetland HVDC link is a critical electricity transmission link and will form part of the electrical transmission grid that is essential to the transport of renewable energy between the locations where it is generated and areas of demand, and the delivery of both Scotland’s and the United Kingdom’s 2030 climate change targets.
The vessel, NKT Victoria, will be used to lay the cable on the seabed. Once the cable is laid on the seabed, the vessel, Grand Canyon III, will be used to trench the cable to the required burial depth in the seabed. Any sections along the cable route that cannot be trenched, rock placement will be undertaken by a rock placement vessel (TBC), to achieve the required protection.
All works will be continuous, 24 hours a day. For any crossings, protection will follow the agreement made with the asset owner. In the period between cable lay and cable burial, or protection by rock placement, the cable will be exposed on the seafloor.
During this time the cable is sensitive to any external impact and constitutes a snagging risk for anchoring, fishing gear or other equipment with seabed intervention. For this reason, the cable corridor will remain closed for any fishing that interacts with the seabed, anchoring or use of other equipment with seabed intervention.
For the cable pull-in part of the installation works at Weisdale Voe landfall, due to shallow water depth, the cable will be floated into the shore from NKT Victoria. For this operation three workboats will be launched from NKT Victoria along with a Fast Rescue Craft (FRC) that will be utilised to support the pull-in operation. This operation could take up to 6 hours to complete. Once the pull-in is complete the workboats will be recovered to NKT Victoria.
To protect the cable in the cable corridor, Guard Vessels will be deployed along the route. It is requested that all vessels maintain a minimum of 500m safe distance from the installation vessels and pass at reduced speed. Fishing gear or other equipment with seabed intervention should not be deployed when approaching the cable corridor.

For more information on the boundaries of the 50 metre Advisory Safety distances please ensure that you have the latest KIS-ORCA information installed - this can be downloaded from www.KIS-ORCA.eu
Please also consult the MMO website : https://www.gov.uk/guidance/marking-of-fishing-gear-retrieval-and-notification-of-lost-gear
If fishing inside the Wind Farm you are advised to use Dhan Buoys anchored towards the middle of the lane with a long weighted feed line rather than Marker Buoys that can be moved by the strong tides and so foul the Turbines.
If in any doubt please contact me
If you know of any fisherman who works the area and does not receive this information or anybody else who would benefit from this information please let me know.
Please do not hesitate to contact me if you require any further information.

Mariners are advised that all foundations monopiles have been installed and all inter-array and export cables have been installed.
Navigation Warning - 08th January 2021
Mariners are advised that the remnants of a Wave Rider Buoy sinker weight and partial rigging are located within the Triton Knoll Offshore Wind Farm Construction site at the following location;
53° 30.442N 000° 50.564E
It is advised that the partial rigging could potentially be floating up to 9.7m above the seabed, reducing the navigable safe water in the immediate area to 10m LAT. Mariners are advised to avoid the indicated position by 250 metres.
Possible Dangers to Navigation - Properties of the polypropylene show that the rope is buoyant, this makes the line sensitive for thruster currents. Taking the site water depth into consideration (19.7m LAT) and the maximum expected height above seabed of the rope 9.7m the line is expected to be floating submerged at approximately -10m LAT. In addition, it is noted that over time sediments will be trapped between the fibres and the heavier rope may finally sink. The polypropylene rope may impose a risk to foul propellers / propulsion of vessels due to the buoyant nature of the rope. As the rope is submerged at a depth of ~-10m LAT the risk is considered minimum for vessels with a shallow draught (<5m) and medium for a vessel with a deeper draught (>5m). Over time sediments will be trapped between the fibres and the heavier rope may finally sink thereby reducing the risk to propellers/propulsion of vessels. The clump weight itself (chain) is expected to have sunk into the seabed and has no significant height above seabed. In addition, the edges of the clump weight are mostly rounded (chain), the risk the clump weigh imposes to fishing activities/gear is therefore considered to be minimal.
Navigation Warning - 16th March 2021
Mariners are advised that two UXO targets have been confirmed within the Triton Knoll Offshore Wind Farm Array.
Mariners are advised that the two confirmed targets are located within 20 metres water depth (LAT) and a 10 metre radius exclusion zone is required around each target. The following table provides the coordinates and a description for each target.
Description of Target | Latitude | Longitude |
Water Depth (LAT) Metres |
Required Exclusion Zone (Metres Radius) |
Archaeological - The item is thought to be an air-delivered bomb. It appears to be in a stable condition and is resting on the seabed. Marine growth and concretion cover the body, indicating it has been in situ for a significant duration. The tail section of the bomb is missing, which is typical of unexploded bombs from WWII found in these circumstances and there is a significant hole in the case. The dimensions and characteristics gathered are consistent with a 500kg German bomb. Considering the state of the bomb the Net Explosive Quantity of the bomb is likely to be <5kg. | 53°31'50.249"N | 00°47'45.908"E | 20 | 10 |

Show MoreUnderwater Noise Monitoring Survey - Rampion 2 Offshore Wind Farm
A fixed monitoring station including a heavy seabed mooring and hydrophone suspended in the water column will be deployed at the monitoring site close to the proposed Rampion 2 Offshore Wind Farm. The monitor will be fully calibrated and configured to record underwater noise levels continuously for a period of up to 20 weeks between circa 1st March and 31st July.
Introduction The Rampion 2 offshore wind farm is a proposed development by RWE Renewables UK Wind Services Limited (RWE) on behalf of Rampion Extension Developments Limited (RED). The offshore element of Rampion 2 would be located within the English Channel, adjacent to Rampion 1, approximately 13km from the Sussex Coast. Rampion 2 would have a generating capacity of up to 1,200MW, with marine cables connecting the Wind Turbine Generators (WTGs) to up to three offshore substations and up to four cables from these substations transferring the electricity onshore.
The construction of the Rampion 2 offshore wind farm is proposed to include impact piling for the installation of piled foundations, and there remains concern from SNCBs, regarding the noise produced during piling. In order to ensure an appropriate level of understanding, monitoring of background noise levels is proposed at a single location close to the Kingmere Marine Conservation Zone (MCZ).
Overview A fixed monitoring station including a heavy seabed mooring and hydrophone suspended in the water column will be deployed at the monitoring site displayed in Figure 1 of the attached NtM. The monitor will be fully calibrated and configured to record underwater noise levels continuously for a period of up to 20 weeks between circa 1st March and 31st July: this would suitably capture the full range of minimum and maximum background noise over the period, across several full spring/neap tidal cycles and result in a comprehensive dataset for the black bream breeding season.
Please be advised that from the 8th March, Rampion Extension Development will be deploying underwater noise monitoring equipment at the location shown in Figure 1. The equipment will comprise a static hydrophone monitoring system with sub-surface riser and pick-up buoys. The total height of the single line deployment will be 2m above the sea floor.
This notification is intended for circulation to all interested parties undertaking or managing activities in the vicinity of the planned survey works. If you would like further details regarding the surveys please contact Maria Milititsky.

Type See detailed map on our bulletin websiteConstruction of Cable Landfall - Greenlink Internconnector Cable Installation
As part of the Greenlink Internconnector Cable Installation the cable landfall will be constructed using a Horizontal Directional Drill, during operations the vessel Pompei will be temporarily anchored close to shore to support diving operations. For safety of the divers, vessel crew and other mariners a small exclusion zone is requested around the vessel. There may be a period when the anchors are in place but the vessel is not in position.
Greenlink Interconnector Ltd. (GIL) is proposing to develop an electricity interconnector between the South-east of Ireland, from Great Island, County Wexford to South-west Wales, at Pembroke, Pembrokeshire.
To allow the offshore cable to be pulled onshore in a later stage, an onshore based Sub SubContractor (VLCV) will commence drilling operations at the Fresh Water West landfall for installation of 2 HDPE ducts. Upon completion of drilling the first borehole, an HDPE pipe is installed by means of push/pull installation.
These push/pull operations require a support vessel, which shall be positioned at the punch out location of the borehole and which shall be moored with a 6 point mooring system during operations. During the push/pull operations, divers will be deployed from the vessel and the vessel will have restricted manoeuvrability. During operations, project crew will transfer daily back and forth to the vessel by means of a CTV operated by Williams Shipping.
Before start of the offshore operations, 4 out of 6 anchors of the mooring system shall be predeployed by an anchor handling vessel on site. In Wales, Williams Shipping will perform the anchor handling operations. These anchors will stay in position until all works have been completed and final demobilisation in Wales is done

From ETAP CPF Seagull oil and gas will be exported to shore through the GAEL and FPS pipeline systems to the Kinneil Terminal onshore.
We already have an ODA established covering the Seagull drill centre and the Egret manifold and would like to request to extend the ODA to incorporate the entire Seagull works area. The extended Offshore development area will be required commencing from September 2021 â March 2023.
