Notice to Mariners - Shetland HVDC Link (Ship to Ship Rock Transfer)

Rock placement is being undertaken by NKT, on behalf of Scottish Hydro Electric Transmission Plc, along the Shetland HVDC Link for Campaign 1 using the rock placement vessel Heimdal R. Due to the maximum load capacity of Heimdal R, transfer of rock is required to be undertaken by ship-to-ship transfer within Sinclair’s Bay, Caithness.

Rock placement is currently being completed by Heimdal R along the Shetland HVDC Link Campaign 1, with an estimated completion date of the 22.12.22. During this time coaster vessels, Famita and Hagland Carrier, will transport rock from Norway to Sinclair’s Bay to complete the ship-to-ship transfer of rock to Heimdal R. All ship-to-ship transfers will be completed in safe sea conditions and in high visibility.

 

A safe and suitable location, free from any potential hazards, within the pre-designated ship-to-ship transfer areas (see chart on the last page of the document) will be chosen on arrival of the coaster vessel within Sinclair’s Bay. Once a suitable location has been chosen, Heimdal R will confirm permission to moor alongside the coaster vessel safely and securely. The coaster vessel will then transfer the rock to Heimdal R using the excavator onboard.

 

Please be aware that during this operation, vessels, Famita, Hagland Carrier and Heimdal R, will be restricted in their ability to manoeuvre as defined under COLREGs (International Regulations for Preventing Collisions at Sea 1972). Masters of vessels are therefore requested to maintain their vessels at a minimum safe passing distance of 500 metres.

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.

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.

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.

Morgan & Mona Metocean Equipment Removal and Floating LiDAR Servicing

Metocean instrumentation within the Morgan and Mona project sites are scheduled for removal. And Floating LiDAR in the same area are scheduled to be serviced.

Metocean instrumentation and floating LiDAR instrumentation have been deployed within the boundary of the proposed Morgan (North) and Mona (South) Offshore Wind Farm Project sites in the Irish Sea.

 

The metocean instrumentation within the Mona and Morgan Project site were deployed successfully in November 2021. Recovery of this instrumentation is now scheduled, having been deployed for 12 months.

 

Until metocean equipment is recovered, it should be noted that instrumentation is deployed on the seabed some distance from the surface buoy; marine users are requested to maintain the safe clearance distances as outlined in Section 3 below. Further details on the mooring design are available in Section 7.

 

The floating LiDAR instrumentation were successfully deployed at the Mona Project site and the Morgan project site in March 2022. A scheduled service of this instrumentation will take place as soon as weather and vessel availability permit. These servicing operations will adopt one of two approaches: (1) a replacement floating LiDAR system will be deployed within the licenced area and the existing system and mooring recovered or (2) the existing system will be recovered to the vessel and the mooring buoyed and left in situ while on shore servicing occurs.

 

It should be noted that instrumentation is deployed on the seabed some distance from the surface floating LiDAR buoy, so marine users are requested to maintain the safe clearance distances as outlined in Section 3 below. Further details on the mooring design are available in Section 7.

 

All equipment will be maintained in position via appropriate mooring systems and will gather metocean data to inform the proposed Project.

Seabed instrumentation frame deployments - South Stack Irish Sea

A seabed instrumentation frame with associated ground line and clump weight is deployed and will be recovered in a suitable weather / tidal window. The ballasted frame weighs around 370kg, measures approximately 1.5m x 1.5m x 1.5m and is connected to a 100kg clump weight and remotely actuated pop-up buoy via a 100m wire ground line. Note: two frames were deployed initially, but one of these has been recovered already.

Inside the Morlais demonstration zone the frame sits on the seabed in more than 30m of water, with no surface infrastructure such as buoys or markers. Vessels will be able to pass safely through the area and above the frames. Use of static or mobile benthic fishing gear in the immediate area should be avoided to avoid the risk of snagging.

 

The position listed here is as deployed.

Shetland HVDC Cable Lay Works Campaign 1

Scottish Hydro Electric Transmission Plc, are undertaking Campaign 1 of the Shetland HVDC Link cable installation. Campaign 1 begins at Noss Head, North of Wick and runs to until approximately KP155. The cable has successfully been laid on the seabed floor. The trenching vessel, Grand Canyon III, has also completed trenching the cable to the required burial depth. For sections that cannot be trenched, rock placement will be undertaken by vessels Heimdal R and Rockpiper in the near-shore area.

Activity Update

 

The cable has successfully been laid on the seabed floor by the vessel NKT Victoria. Trenching of the cable to the required burial depth in the seabed has been completed by the Grand Canyon III. For the sections remaining along the cable route that have not been trenched, rock placement will be undertaken to achieve the required protection. The rock placement works will be completed in the near-shore area (Campaign 1A) by vessels Heimdal R and Rockpiper. All works will be continuous, 24 hours a day.

 

Within the Noss Head Marine Protected Area the cable has been surface laid and protected by a cable protection system. 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.

 

Please be aware that vessels Heimdal R and Rockpiper will be restricted in their ability to manoeuvre as defined under COLREGs (International Regulations for Preventing Collisions at Sea 1972). Masters of vessels are therefore requested to maintain their vessels at a minimum safe passing distance of 500 metres.

 

Heimdal R and Rockpiper will display the appropriate shapes and lights in accordance with COLREGs Rules 16 and 18.

 

Co-ordinates of the cable corridor and charts of the working area are provided below. 

 

Guard Vessels

 

To protect the cable during installation activities Guard Vessels will be placed at approximately 15km intervals along the cable route. To provide the required coverage, approximately 7 guard vessels are expected to be utilised. The primary purpose of the Guard Vessels is to guard any unprotected cable along the cable route. The Guard Vessels will operate on a 24hr / 7 day per week basis. Any exchange of vessels shall be on site and coordinated so the unprotected cable is never unguarded.

 

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.

Dye Dispersion Study - Carnoustie

Carry out dye and drogue dispersion study 2Nm north of Carnoustie. Late October into late November 2022

The dispersion study will involve the release of surface patches of tracer Rhodamine WT (a pink dye that disperses in seawater over a few hours) over a 12.5 hour tidal cycle. The amounts of dye used will be in accordance with the approved list and guidelines. The resulting dye patch will be monitored and tracked for around 2 hours per patch and maximum travel of the dye patch will be around 1.0km before it has dispersed beyond the limits of detection. Up to 4 surface drogues with 1m sail depth will be deployed at the same time as the dye release and these are fitted with gps loggers that will record their position every few minutes. These will be allowed to drift over the same time period as the dye dispersion before retrieval. An ADCP current meter may be deployed on the seabed close to the intended outfall position for the duration of these studies which is likely to last 30 days. 12 sediment samples will be collected from the seabed and benthic analysis carried out along with 24 seawater samples. This will give a better understanding of background conditions and allow for more accurate model simulations to be carried out.

NW Schooner Subsea Well - Missing Debris Cap

The Debris Cap for the NW Schooner subsea well has been identified as missing, leaving the wellhead more vulnerable to snagging on fishing nets. The Debris Cap is 4.5m x 3.9m x 1.4m and approx 3.5 tonnes, whilst the wellhead stands 6m off the seabed.

The approximate dimensions of the Debris Cap is 4.5m x 3.9m x 1.4m with a weight of approximately 3.5 tonnes. It is not known whether the Debris Cap is lying within a 500m zone of the well. A 200m x 200m area centred on the well has been searched, with no sight of it. Therefore the exact location of the Debris Cap is unknown. The loss of the Debris Cap leaves the NW Schooner wellhead more vulnerable to snagging from trawler/fishing nets.

Llyr Offshore Wind Farm Geophysical and Environmental Survey

A geophysical and environmental survey will be carried out between 21st September and 1st December. The geophysical survey will employ MBES, SSS, High-resolution Sub-Bottom Profiler and a single magnetometer. The environmental survey will acquire a drop down video footage and grab samples. All geophysical survey operations involve towed survey equipment (SSS, Magnetometer and SBP), and no equipment will be left on the seabed.

Please be advised that from the 21st of September 2022, N-SEA will be conducting a geophysical and environmental surveys within the area shown in paragraph 5. The survey consists of an offshore windfarm location, and its northern export cable route corridor. The geophysical survey will employ MBES, SSS, High-resolution Sub-Bottom Profiler, and a single magnetometer. The environmental survey will acquire drop down video footage and grab samples.

The geophysical and benthic survey works will be completed by N-Sea personnel on the survey vessel ‘Braveheart Spirit’. Full vessel details are presented in paragraph 6 below.

All environmental sampling will be executed by N-Sea subcontractor Ocean Ecology.

All geophysical survey operations involve towed survey equipment (SSS, Magnetometer and SBP), and no equipment will be left on the seabed. During geophysical and environmental surveys the vessel will be restricted in manoeuvrability and will require large turning circles. All vessel operating within this area are requested to keep a 500 m distance and pass at minimum speed to reduce vessel wash. The survey vessel will always be listening to Channel 16 but can set any other channel as required. Throughout survey operations, the vessel will be displaying the appropriate lights and shapes as required under COLREGS Rule 27(b).

All nearshore activities will be undertaken during daylight hours. All offshore activities will be undertaken on a 24 hour basis.

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 geophysical and/or environmental surveys, please contact the N-Sea project manager using the contact details at the bottom of this communication.

All mariners are reminded of their responsibilities under the International Collision Regulations and are reminded of Marine Notice No 17 of 2007 which gives general advice in relation to the activities of vessels engaged in survey work for hydrographic, seismic, fishing research and underwater operations.

Liaison and General Operational Principles

  1. We will ensure advance notice of survey works is provided to all marine users.
  2. As near-shore areas have the potential to hold higher densities of static fishing gear, where practicable geophysical and environmental survey operations within the near-shore area will be undertaken during daylight hours.
  3. Should areas of high fishing density be identified, best efforts will be made to modify survey plans (either the location of survey or timing of operations) to avoid damage to both survey and fishing gear.

Animal tracking acoustic receivers (Cornwall south coast)

The University of Exeter with the Cornwall Inshore Fisheries & Conservation Authority have deployed animal tracking acoustic receivers along the south coast of Cornwall. The receivers are low profile and consist of a yellow sub-surface float with an integrated electronics package. The unit has an attached rope drum and floats just above the seabed. Each receiver has a ground line running approx. 100m from the unit. There are no surface markers associated with these devices.

The University of Exeter have deployed acoustic receivers along the ~50m depth contour of the south Cornwall coast. These receivers collect information on the movement and residency of electronically tagged Atlantic bluefin tuna. Other receiver networks have been deployed across the English and French Channel, including the Isles of Scilly, to detect these highly mobile species and other tagged fish species as part of the FISH-INTEL project.

 

The receivers are low profile (75cm height, 45cm width and <0.75sqm) and will be serviced several times each year. The receivers are retrieved by triggering (from the surface) the release of a recovery line from the unit. Receivers are moored to the seabed using rail chair clump weights. There is no permanent tether to the surface. Each receiver has a 100m ground line to provide a retrieval backup.

 

If a receiver is accidently recovered please retain and contact the University of Exeter (using point of contact).

The ARCs are low profile (35cm height and <0.75m2) and consist of 3x11 inch floats fixed to a delrin plate that holds the acoustic receiver floating ~1m above anchor (~70kg chain links). The ARCs will be serviced twice a year remotely from a vessel and completely removed at end of 3-5 years. There is no surface marker associated with these devices.

NatureScot, in collaboration with University of Exeter, have deployed 10 Acoustic Reciever Cannisters in the Sea of the Hebrides around the Gunna Sound area (as part of Marine Scotland Science Alba Na Mara June research cruise).

The intention of deploying the ARCs is to collect acoustic information on the movement and residency of tagged basking sharks with the Marine Protected Area, to provide data to aid conservation.

 

The ARCs are low profile (35cm height and <0.75m2) and consist of 3 x 11 inch floats fixed to a delrin plate that holds the acoustic receiver floating ~1m above anchor (~70kg chain links). The ARCs will be serviced twice a year remotely from a vessel and completely removed at end of 3 - 5 year (end date will depend on battery life of tags and when the tags are deployed). There is no mooring line associated with these devices, and are retrieved by triggering (at surface) a recovery line from ARC unit, so there is no tether to the surface.

PrePARED Fish Tracking Array - Beatrice and Moray East Offshore Windfarms

Marine Scotland Science (MSS) intend to install 87 acoustic fish tracking moorings in the Beatrice and Moray East Offshore Windfarms areas (BOWL (38 moorings) and Moray East (49 moorings)) as part of the PrePARED programme of works. PrePARED is a collaborative research project coordinated by MSS which aims to concurrently study predator (seabird and marine mammal) and prey (fish) distribution and behaviour in and around offshore wind farms. Deployed: 10 April 2022. Removed: 30 August 2026.

Marine Scotland Science (MSS) intend to install 87 acoustic fish tracking moorings in the Beatrice and Moray East Offshore Windfarms areas (BOWL (38 moorings) and Moray East (49 moorings)) as part of the PrePARED programme of works. PrePARED is a collaborative research project coordinated by Marine Scotland Science which aims to concurrently study predator (seabird and marine mammal) and prey (fish) distribution and behaviour in and around offshore wind farms. The moorings hold research equipment that support hydrophone receivers. These receivers log the presence of fish, such as Cod, Haddock and Whiting which will be tagged with acoustic ID transmitter tag s (they will also record salmon and seatrout smolts migrating from Moray Firth Rivers tagged by the Atlantic Salmon Trust (AST) should they pass within range).

 

The moorings will be deployed from the 10th of April 2022 by a the Waterfall operated by Moray First Marine. The moorings will be removed by the 30th of August 2026.

 

Acoustic fish tracking moorings will not be surface marked and will be located on the seabed. The array moorings will extend vertically no more than 4 metres. The moorings will be serviced by boat, using the inbuilt acoustic recovery system. In the unlikely event of failure in the acoustic release system an ROV will be used from the same boat to service the mooring. Please note the acoustic fish tracking moorings are being deployed as close to the wind turbine generators as possible to minimise interference with fishing operations (50m), should these be accidently caught only the instruments are required to be returned and the location of the discarded weight should be supplied to MSS for recovery later.

 

Fish capture traps and timed-release cages (8 traps and cages in total) will be deployed in Moray East and Beatrice sites. These traps and cages will be used in the capture and managed release of fish needed for internal electronic tagging with acoustic ID transmitter tags. Traps and cages will be present at Moray East and Beatrice for up to 10 days commencing 13th of April. Traps and cages will move at 1 to 2-day intervals. All traps and cages will be marked with creel style floats and clearly marked “Marine Scotland Science” and be marked with an AIS beacon (visible as MARLAB 1 – MARLAB 8). Traps and cages will be at least 100 metres from turbine locations. Locations of traps and cages will be notified to the relevant windfarm Marine Control Centre as appropriate.

Possible Hazards (initial ‘trawl sweep’ findings)

The Moray East Over Trawl Survey (Export Cable Trawl Sweep) was undertaken by the MV Sardonyx between the 1/9/2021 and the 5/9/2021. The work was undertaken using appropriate gear types for the locations outlined below, with the crossings being undertaken successfully. At Section 1, at crossing position 57°41.962'N 002°33.078'W, the gear encountered a peak tension and a reduction in gear spread.

At this location, the export cables are buried to the required depth and the trawl gear did not pass over any rock protection or any known boulders, as such the cause of the peak tension is unknown. This will be investigated by the project at the earliest available opportunity.

Neptune E&P UK Ltd would like to request to establish an additional offshore development area in Block 22/29C for the Seagull Umbilical location.

The Seagull Field is located on UK licence P1622 Block 22/29C. 17km south of the Eastern Trough area Project (ETAP) Central Production Facility (CPF). Neptune will develop the Seagull reservoir as a subsea tie‐back to existing seabed infrastructure over the BP operated ETAP CPF. The development is high pressure and high temperature and Neptune is the Operator for the subsea development. Neptune will also drill and complete the Seagull Wells and shall retain overall Project responsibility.

The Seagull development will require installation of new subsea equipment as follows: Four Xmas Trees; a 4 slot manifold; a 17km control umbilical (including hydraulic, electrical and chemical supplies) direct from ETAP to Seagull; a 5km 10” production pipeline; a 5km 3.5” wash water pipeline from Seagull to the existing Egret manifold; and a Wye manifold adjacent to the existing Egret manifold, through which the new Seagull production pipeline will connect with the Heron cluster pipeline system connected back to the ETAP CPF. 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 ‐ March 2023.
