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

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

Intention to deploy buoyed scientific mooring, Moray West OWF



Seiche Ltd. in collaboration with Moray West OWF wish to inform you of our intention to deploy a short-term mooring of scientific equipment, within the area of the Moray West OWF. The equipment is a passive acoustic monitoring system, and we plan to deploy this for less than a 5-day period.


We believe that our mooring is unlikely to represent a hazard to navigation as it would be located within the charted perimeter of Moray West OWF. We have three possible mooring locations (see below). It is likely that only one mooring location would be used. however, potentially, the buoy may be moved between all three locations.

 

RTSM-01 58.0715 -3.1061 RTSM-02 58.0714 -3.1230 RTSM-03 58.0714 -3.1569

 

The surface marker buoy is yellow with a 50 cm steel tower and solar panels. It is marked with a light that emits a pattern of 1 x yellow flash every 5 s. It also carries a passive radar reflector. The buoy will be moored using a twin anchor system, with two mooring riser buoys also visible at the surface. The two anchors consist of large link chain clump weights (2 x 150 kg). All equipment will be recovered and removed on completion of the activity.

Surface Laid Cable - The Whitley Bay Stub Route (2)



The installation of the Havhingsten fibre optic telecommunication Whitley Bay Stub Route has been completed. Due to challenging soil conditions and rocky seabed, there are sections of surface laid cable and areas with shallow burial. No further operations to bury this section of cable are planned due to the presence of rock. The cable is protected by the armoured cable type and from the BMH up to kilometre point (KP) 0.474 the cable is additionally protected by Articulated Pipe.


Please be advised that installation of the Havhingsten fibre optic telecommunication Whitley Bay Stub Route has been completed.

 

The supplier of the Havhingsten cable is Alcatel Submarine Networks (ASN). Intertek are the environmental and permitting consultants.

 

The Whitley Bay Stub Route has been installed between the Beach Man Hole (BMH) and the territorial sea limit but it will not yet be connected to the telecommunication network. This cable is to provide infrastructure for the network to expand relatively easily when demand is required within the next 10 - 15 years.

 

Due to challenging soil conditions and rocky seabed, there are sections of surface laid cable and areas with shallow burial (less than 0.20m burial depth), coordinates can be found below. No further operations to bury these sections of cable are planned due to the challenging soil conditions. The cable is protected by the armoured cable type and from the BMH up to kilometre point (KP) 0.474 the cable is additionally protected by Articulated Pipe.

 

Coordinates for the surface laid cable and shallow burial areas are provided in the attached Notice to Mariners.

 

Post-Lay Inspection & Burial (PLIB) by jetting for the section of surface laid cable close to the territorial sea limit was completed on the 1 November 2022.
