Please be advised that Fugro will be performing site investigation works on behalf of Inch Cape Offshore Limited. The works are to be carried out within the Development Area (see Figure 1 below) for the consented Inch Cape Offshore Wind Farm located within the Outer Firth of Tay

The first phase of the site investigation works are now complete. The second phase of the site investigation works will commence on or after the 1st of November 2021, weather permitting and take up to 25 days to complete. The works will be undertaken using the vessel Fugro Scout.

During the survey the vessel will be displaying the relevant RAM lights and displays during periods of restricted manoeuvrability. Whilst not recommended, vessels entering the survey area are requested to maintain a 500m safety zone. 

Each 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.

Once installed in the Morlais demonstration zone the frames will sit on the seabed at depths of at least 30m, 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.

Three possible deployment locations are listed for the two seabed frames: a final pre-installation survey by subsea video camera will be completed at these locations before the equipment is deployed on the two most appropriate locations. This notice will be updated with the as-deployed locations.

Turbine parts and tool fell into water during a major component exchange at turbine B01:

• 3 x 61m blades:
  • Mainly Fibreglass and Wood with bearings and pitch gear rings.
• Hub, containing:
  • 3 x Pitch Motors (22 litres of Mobil SHC Gear 150 in each)
  • 3 x 30 batteries. Lead Acid 12V 12AH.
  • 4 x Electrical cabinets containing MCB/Relays/Cabling
  • 3 x Grease pumps (empty).
  • The rest consists of the steel frame/ fibreglass cover, some fibreglass ladders and electrical switches/sensors & cabling.
• Blade clamping tool (incl. batteries and 50l hydraulic oil tank)
• 2 x Foam Wraps for the blade tips with length of rope attached.

Hub, blades and blade clamping tool understood to be on seabed. Fragments of broken blade on sea surface.

The Northern Producer FPF has been removed from it’s moorings and towed to port for decommissioning but the subsea assets within the Northern Producer FPF 500m zone will remain in place on the seabed and could pose a snag hazard to fishermen therefore the Thistle Alpha Platform ERRV will act as a guard vessel until the 500m zone clearance is performed in 2022.

This includes the 8 No Risers draped over the Mid Water Arch (MWA), the MWA Clumpweight Guide Frame, the Riser Base Structure (RBS) and the surface laid pipelines / Umbilicals.  The MWA will remain in the water column at a depth of 112m and will remain tethered to the seabed via the clumpweight guide frame. The risers will remain draped over the MWA with one end on the seabed and the other end will remain connected to the RBS so that they remain stable. The existing stabilisation mattresses will remain in place over the surface laid pipelines/umbilicals.

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.

Navigation Warning - 25th May 2021

Mariners are advised that during a Man Overboard Recovery drill a “Dead Fred Casualty” was subsequently lost, presumed sunk to the seabed in the following position;

Latitude - 53° 30.27’N

Longitude - 000°40.55’E

Water Depth – 79m LAT

We will be deploying three scientific Acoustic Doppler Current Profilers on the sea bed for 12 months from October 2021 to collect currents data for environmental monitoring and hydrodynamic model validation.  The instruments have no surface markers and will be recovered using acoustic releases.  Two of the instruments will be inside low profile trawl-resistant frame (Little Minch, west of Skye, and Linn Crowlin, east of Skye) and one inside a steel frame (Loch Erisort, east of Lewis).  See attachment for photos of the frames, a chart with their position and their positional details.

Staff from the Scottish Association for Marine Science (SAMS) will deploy and recover three scientific moorings inside the Kincardine Offshore Wind Ltd. (KOWL) wind farm lease site, ~15 km offshore from Aberdeen. Expected deployment duration will be several weeks, from mid-October to late November 2021. This may need to be extended if adverse weather conditions prevent timely recovery.

Moorings will contain passive acoustic recording equipment intended to record sound produced by operational wind turbines. Moorings will be located within the KOWL lease area boundary, at 200 m, 600 m and 2,000 m from one of the wind turbines, at water depths of around 80-90 m. Moorings will extend up to 110m along the seafloor using weighted lines, and will not extend more than a few meters into the water column (there will be no surface expression). Deployment and recovery will take place using a combination of ROV and acoustic release-based methods, using Moray First Marine Ltd. vessels 'Coral winds' and/or 'Waterfall' travelling from Aberdeen. Deployment and recovery activities of all three moorings are expected to be completed within a single working day (again, weather permitting).

On behalf of Seagreen Wind Energy Ltd, Seaway 7 will install seabed scour protection rock to the foundation structures within the site boundary. The Flexible Fall Pipe Vessel (FFPV) Bravenes will transport and install the rock on the seabed using its flexible fall pipe system. This allows the scour protection to be installed with a high degree of accuracy. An ROV at the end of the fall pipe will be utilised to control the flow of rock to the seabed.

The main lay cable installation activities between the landfall at Bude, Cornwall, out to the UK Exclusive Economic Zone (EEZ), were completed on 7th October 2021. A burial report was submitted to the MMO on 10th September 2021 in line with condition 5.2.19. Post-lay inspection & burial (PLIB) operations are due to take place at three locations and post-lay inspections (PLI) are due to take place at ten locations within the UK EEZ.

These operations are due to commence on the 17th October 2021, utilising the vessel Ile de Brehat call sign: FOUC and will last approximately 1 week.

The exact start and finish date will be dependent on the prevailing weather conditions and work progress.

It is requested that all vessels operating within this area keep their distance, maintaining at least a 500 m exclusion zone, and pass at minimum speed to reduce vessel wash.

Notice of Post-Lay and Burial Works

Please be aware, there are three sections of the Amitié cable within UK Exclusive Economic Zonewhich are subject to the Post Lay Inspection and Burial (PLIB) which will be carried out by the Ile de Brehat, commencing on the 17th October 2021

Nature of Operations

The vessel Ile de Brehat will be operating from approximately 270km from the landfall at Widemouth Bay, Bude, UK, out to the limit of the UK EEZ conducting the PLIB and PLI operations. These operations will be conducted on an ongoing 24 hour basis. A listening watch will be maintained on VHF Channel 16, and the vessels will actively transmit an AIS signal.

RWE Renewables UK Ltd at Rampion windfarm would like to inform mariners that we are carrying out essential maintenance on the wind turbines.

This work is due to commence on 20th October 2021 within the Rampion OWF Area, depending on weather.

The works involve using a jack up vessel to exchange large components in the nacelle of the turbines at I12, I13, J12 and H14 using the vessel crane.

The current outline planning is as follows: Start Date: 20th October 2021 Vessel Name : DEME Neptune

The vessel will require a 200m exclusion Zone from its location at I12, I13, J12 and H14.

See detailed map on our bulletin website

The exact survey duration and completion date will depend on weather and progress of the works

See detailed map on our bulletin website

In addition to the deployment of two new buoys, operations will include the recovery and removal of a LiDAR buoy that is presently deployed at the same site.

The equipment will be located at the Blyth NOAH offshore Met Mast validation site.  

The equipment is an integrated Seawatch Wavescan buoy and ZX 300M LiDAR; the purpose of the equipment is to collect oceanographic and meteorological data using a single platform. The equipment is supplied and charged by an onboard power system which uses methanol fuel cells and solar panels to recharge onboard lead acid batteries.

The equipment is equipped with a F1 (5) Y 20 s light with 4-5 nautical mile range; the light is mounted at the top of one of the masts, approximately 4 m above sea level.

A Remotely Operated Vehicle will be deployed to identify the moorings. The moorings will then be bought to deck and transported to shore.

Wave Buoy Mooring:

Before start of the ROV operation:

• The vessel will run survey lines between original location and recovery position (see coordinates below).

ROV search locations

• 51°28'35.34"N     5°36'8.10"W (original location)
• 51°28'37.44"N     5°36'11.04"W (potential recovery position)

Damaged Mooring:

ROV search locations:

• 51°27’45.29”N    5°37’7.32”W (original location)
• 51°27'45.10"N     5°36'39.66"W (estimated release point)

In case the mooring system cannot be found at the above locations, a survey will be completed within the search area:

These locations identified will be surveyed to ensure all possible known locations have been searched.    

A further NtM will be issued to confirm the outcome of the recovery attempt.

It is recommended that mariners continue to remain vigilant and make note of the approximate mooring locations.

The following vessel will be carrying out construction activities between the Everest  East Expansion North Manifold and the new LAD well in Block 22/10a in the UKCS:

• Seven Pacific (call sign 2DLM3) will be carrying out umbilical and flexible flowline installation works from approximately 11th October 2021 to 31st October.

Mariners are advised that SSE Renewables will be deploying a bottom mounted ADCP device recording metocean data at three locations within the proposed Berwick Bank Wind Farm array area. An associated guard buoy is currently deployed at each location. All locations referred to are outlined in Table 1 and displayed Figure 1.

It is proposed that three stumpy moorings (M) and a near-bed frame (NB) will be installed on the sea bed within 175m to the three guard buoys which were installed during a previous wave buoy campaign. These locations are all within the Berwick Bank Wind Farm (BBWF) in the outer Firth of Forth on the east coast of Scotland. It should be noted that the near-bed frame will only be situated at one of these three sites at any one time.

The equipment will be deployed during October 2021, with an estimated start date for deployment set for the 14th October 2021. However, this may be subject to change due to weather and/or operational delays. The stumpy moorings will be deployed for 12 months with maintenance and monitoring completed at each three-month interval. The one near-bed frame will be deployed for three months at two sites and 6 months at one site, equating to a deployment duration of 12 months in total.

The Abeko Server 2 Will carry out dredging activity to form two pre-cut trenches for DBA and DBB cable route corridors using the on-board long reach excavator. There will be spoil management activities being carried out throughout, to ensure the soil heaps don’t reduce the water depth by more than a statutory 5%. She will be carrying out the excavation activities on DBA and DBB during the night. The duration of these works is estimated to be seven days. See fig 2 below.

The Haven Seariser 4 will also remain on site 24 hrs during operations, unless threatened by extreme weather, continuing diving operations. These may be carried out in the hours of darkness. A short safety message will be broadcast on CH16 advising of diving operations starting and ceasing.

The MTS Valour will be anchored in the field during the nearshore activities. She will remain on station/site during the night and manned 24 hours throughout. The MTS Valour will provide assistance during diving operations and any barge movements required.

The RHIB Celtic Mara will be carrying out Multi-Beam Echo Sounder (MBES) surveys of the seabed and along the pre-cut trenches throughout the dredging activities. The survey gear will be positioned on a side mounted pole and extended into the water. Celtic Mara will transit daily from Bridlington Harbour to the Haven Seariser 4 and Abeko Server 2

During survey operations the Celtic Mara will be restricted in her ability to manoeuvre. It is requested that all vessels give the Celtic Mara a 500m safety clearance zone and reduce speed when passing. She will display the appropriate lights and day shapes.

During dredging and diving operations it is requested that The Abeko Server 2 and Haven Seariser 4 be given a 500m safety clearance zone. Diving flag ‘Alpha’ and the appropriate lights will be displayed during diving operations.

A Work-class Remotely Operated Vehicle (WROV) will be deployed from the vessel at each location to identify and relocate targets up to distances of around 100m.

During the operations the vessel will be restricted in its ability to manoeuvre and will display the appropriate day shapes and lights. Passing vessels are requested to maintain a minimum 500m safety distance from Noordhoek Pathfinder, reducing speed to minimise wake disturbance.

Please be advised that the remaining post-lay burial (PLIB) works of the Havhingsten fibre optic telecommunication cable system have now been completed in the Irish Sea, but there are three areas of surface-laid cable which are pending rock placement works.

There is a maximum of 25m of cable surface laid with Uradact protection either side of the crossings listed below. Rock protection works will be carried out during the second half of 2021. It is advised that extra care is taken when vessels are operating near the areas and that no vessel should trawl within 0.25 nautical miles from the listed coordinates prior to rock placement. The rock berms will be over trawlable and in-line with industry standards.

Please find attached a chart showing the results of the Greater Gabbard OFTO export cable survey. The chart lists the changes to the exposures on the three export cables, on the inshore section between KP 3 and KP 5 with a free span remaining around KP 4. Between KP 36 and KP 38 there are some exposed sections as the cables enter the site. In addition, although listed as exposures on the chart, there are areas of shallow burial at KP10 and a cable exposure on the interconnector cable within the site.

The exposed/shallow burial areas are shown as the coloured dots on the cable route highlighted in a black box.  Equitix (Greater Gabbard OFTO) have asked that all Fishermen operate with caution when fishing anywhere on the cable route and particularly the areas that are shallow buried around KP10.’

Coordinates of exposed/shallow burial areas are shown on the attached chart.

The OFTO is updating its risk assessments to determine the extent of remedial measures that may be required. Equitix intend to provide an update on remediation after the risk assessment exercise is complete.’

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.
