Application of Triton Knoll Wind Farm Safety Zones During Construction

The Secretary of State has granted the Application of Safety Zones on the Triton Knoll Wind Farm Project as follows:

  • 500m “rolling” safety zones around any structure where construction is being undertaken (as indicated by the presence of construction vessels).
  • 50m pre-commissioning safety zones surrounding partial structures or completed structures prior to commissioning.

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

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

Grand Canyon III will be restricted in its ability to maneuver as defined under COLREGs (International Regulations for Preventing Collisions at Sea 1972) and will display the appropriate day shapes and lights. The vessel will also transmit an Automatic Identification System (AIS) message.

 

In the period between cable lay operation until the cable has been permanently protected by means of burial or rock placement, the cable may be locally exposed on the seafloor and the construction working corridor will remain closed for any static fishing, anchoring or use of other equipment with seabed intervention. 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.

 

To protect the cable in the 500m working corridor, guard vessels will be deployed along the route (described in a separate NtM LF700013-ESI-DOG-NOT-0008). The primary purpose of the guard vessels is to protect the exposed cable along the Dogger Bank C Export Cable corridor by monitoring and issuing warnings to marine traffic operating within 6Nm of the construction area with a Closest Point of Approach (CPA) < 1.5Nm

Export Cable Guard Vessel Deployment - Dogger Bank C Export Cable Route



Installation of the Dogger Bank C Offshore Windfarm Export Cable will commence on the 19th of March 2024. Guard vessels will be deployed to protect the cable bundle from the start of cable lay until the cable is adequately protected by means of trenching or rock placement.


To provide the required coverage, approximately 16 guard vessels will be used in the period from the 19th of March 2024 until the 30th of November 2024. Durations at each location will depend on progress of the cable installation, trenching and rock placement operations. Not all the vessels are expected to be used concurrently.

 

The primary purpose of the guard vessels is to protect the exposed cable along the Dogger Bank C Export Cable corridor by monitoring and issuing warnings to marine traffic operating within 6Nm of the construction area with a Closest Point of Approach (CPA) < 1.5Nm. More specifically, the focus will be on those vessels with potential to be engaging in bottom contact activities such as fishing and anchoring, as these activities pose a risk not only to the exposed cable bundle but also to the vessels themselves.

 

The guard vessels will be clearly marked and display a highly visible "GUARD" sign on each side. The vessels will operate 24hrs, in all but extreme weather. Exchange of vessels on site will ensure the relevant section of cable is never left unguarded.

 

In sections where cable protection has been completed, guard vessels will be released, and sections will be opened up for fishing or use of other of equipment with seabed intervention. This may not necessarily be in a sequential order from shoreside outwards.

Construction of the Princess Elisabeth Island. The exclusion zone around the construction site is marked by 4 cardinal buoys (ELI-N, ELI-E, ELI-S and ELI-W).


Transmission system operator Elia is building the Princess Elisabeth Island in the Belgian part of the North Sea. This artificial energy island is an extension of the electricity grid in the North Sea. It connects the future wind farms of the Princess Elisabeth Zone with the Belgian coast and creates new connections with neighbouring countries.

 

The energy island is built centrally in the Princess Elisabeth wind zone, approximately 45 km from the Belgian coast. Construction of the island will take several years. To ensure safety during the works, the Belgian government defined an exclusion zone within which only work vessels are allowed. This zone is marked by 4 cardinal buoys (ELI-N, ELI-E, ELI-S and ELI-W).

 

Seabed preparatory works took place in spring and summer 2024. Further installation works will proceed from spring 2025. The exclusion area remains in force at all times.
