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. 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

Seismic 2D Survey - RDI21 - MCG21001 (August operations)

Geoex MCG will be acquiring the Regional Deep Imaging Project 2021 (RDI21) between May and September 30th, 2021. The survey is a cross border 2D seismic survey in Norway, UK, Faroe Islands and Denmark.

The aim of the survey is to image deep seated crustal structures in the North Sea and a single source of 6,270 cu.in and one cable of 12 km length towed at 15-30m depth (slant) will be used. The survey will be carried out by the seismic vessel M/V Akademik Lazarev (UAJS) and Jan van Gent (YJVF4) will be the support vessel.

 

There will be two FLOs onboard, one Norwegian from Geograf Maritime and one from SFF Service Limited (Scottish Fishermen's Federation). In addition, the vessel will have MMO and PAM operators onboard. 

 

Since RDI21 is a very regional survey, there will be some flexibility in deviating from the preplotted survey lines, if needed.

  

* The survey has been divided into several notices where each notice contains the lines that are planned to be acquired within the time frame specified in the heading. The .png map shows the full RDI21 2D survey outline.

Viking Link Project - HVDC Cable Laying and Burial

Mariners are advised about landfall works at Boygrift, Lincolnshire (English Landfall) planned for the Viking Link project which is an HVDC electricity transmission interconnector between Denmark and England.

Cable lay and burial works of the HVDC installation are planned to take place from: • Cable lay 10th May –23rd June 2021 • Cable Burial 12th May – 30th July 2021

The route length of the main HVDC interconnection (2x bundles power cables + 1x Fibre Optic Cable) is in the order of 620km. The work covered by this NtM is covering the first campaign of 51km in length starting from the UK the landfall at Boygrift.

 

The Cable Lay works are being carried out by: Prysmian PowerLink using Cable Enterprise Call Sign 2FOV9. Supported by a tug Norne Call Sign PCJR.

 

The Cable burial works are being carried out by: Asso.subsea using Atalanti Call Sign 5BYY2 using the trenching tool AssoTrencher V and the Argo Call Sign 5BDF3 using the jetting tool AssoJet III and trenching tool AssoTrencher IV.

 

Vessels are requested to pass at a safe speed and distance and fishing vessels are advised to remain a safe distance, approximately 550m (0.3 nautical miles) from the areas identified. During these works the vessel will have restricted manoeuvrability as it completes its work scope.

 

Deployed Guard Vessels will monitor the exposed areas of cable while burial progresses and advise of safe distances locally.

 

VHF CH 16 will be monitored at all times and will be used to contact the coastguard in the event of an emergency.

 

Works overview Following completion of the landfall the Cable Laying vessel Cable Enterprise will surface lay the cable on the seabed along the HVDC cable route.

In periods while the cable is exposed on the seabed guard vessels will be stationed to monitor the cable and provide advice to mariners.

 

Cable Burial will follow soon after the cable lay operations carried out by two vessels Atalanti and Argo. Where cable burial is not possible (due to service crossings and / or where seabed conditions are unfavourable), guard vessels will remain on site.

 

Service crossing As part of the first campaign the Viking Link HVDC cable crosses 11 existing service. While awaiting the post lay protection operation, Guard vessels will remain in place to monitor the exposed cable.

Unmanned vessel survey in Hywind Scotland Wind Park area

Use of a 2 meter long remotely controlled unmanned vessel to collect fish biomass information for the Hywind Scotland Wind Park area during June and July

As part of the Hywind Scotland Wind Park, Equinor has subcontracted Akvaplan-niva to perform a survey using an autonomous vehicle – Sailbuoy – in the park area. The Sailbuoy is only 2 meters long and weighs 60 kgs. It was deployed from Bergen on the 8th June and estimated arrival at Hywind Scotland is 29th June.

 

The Sailbuoy will have a pre-programmed mission plan, and will communicate to shore via satelittes. The Sailbuoy is driven by wind and sun, and the vehicle is equipped with solar panel and an echosounder as well as sensors for temperature, salinity and fluorescence.

 

The purpose of the study is to collect relevant data on fish in the Hywind Scotland area using instrumented glider. The method is expected to mainly give data on prevalence and biomass, and less information on biodiversity. The data gathering in Hywind Scotland will take approximately 30 days from arrival and completion is estimated around 29th July. After ended campaign in the wind park, the Sailbuoy returns back to Bergen for retrieval. The results from the glider campaign is important also for further technology development.

 

The Sailbuoy is collision and shock proven. It will be labelled with contact information.

Sound measurement study - Hywind Scotland Pilot Park

Hywind Scotland Pilot Park is performing a sound measurement study where the purpose is to document the operational noise. Successful retrieval of control sound recorder performed January 24. Failed retrieval of the sound recorder in wind park.

Update June 10:

A second attempt at retrieval of the sound recorder in Hywind Scotland Pilot Park will be made by end of August.

Update February 5:

Successful retrieval of control sound recorder performed January 24. Failed retrieval of the sound recorder in wind park.  A second attempt for retrieval of the sound equipment in the Hywind Scotland Pilot Park is being planned. The notice is prolonged and the location of the retrieved control equipment is removed from the notice.

-----

As part of the Hywind Scotland Wind Park, Equinor has subcontracted Jasco Applied Sciences to perform sound recordings in the park area and in a control location in Buchan Deep (near cross over point between the FORTIES to CRUDEN Bay oil line and the GAS line).

 

The purpose of the sound measurement study is to document the operational noise from floating offshore wind turbines and their substructures, mooring lines and cables. It is part of an internal Equinor Research &Technology project that aims to increase knowledge on possible environmental implications of floating offshore wind, i.e. in this particular study, the possible impact ranges of sound from the wind park on marine mammals and fish. The results from the sound measurement study is important also for further technology development.

 

The Equinor contracted “MCS Swath1” (crew vessel) will be used for the deployment and retrieval of the sound recorder equipment (hydrophones). The field activity in connection with both deployment and retrieval will take one day, however, the recording period will be approximately 3 months from ultimo October 2020 to ultimo January 2021.

 

The recorders were deployed October 21. Yet, no exact date is set for the retrieval of the equipment (ultimo January 2021).Activity prolonged.

 

All Equinor installed equipment shall remain in position for the duration of the survey, but all equipment will be removed from seabed when the recording period is over. Also, there will be no bouys on sea surface or lines in the water column. All equipment will be placed on sea floor at approximately 100 meters depth by the help of an anchoring plate, which fastens the equipment and eliminates drifting of equipment. The equipment will have a height of maximum 1 meter above seabed, and the plate mooring system has the dimension 914 x 527 x 864 mm.

 

This equipment collects data and information of environmental importance and could get damaged or lost if trawled over.

 

When the equipment is retrieved, the acoustic release will be activated and the equipment will be lifted by crane.

Neart na Gaoithe Offshore Wind Farm - Dropped Object

Mariners are advised that during operations on Neart na Gaoithe Offshore Wind Farm Limited (NnGOWL) a piece of equipment has been deposited on the seabed and forms a temporary hazard, until recovery is performed between August and October 2021.

The equipment has been deposited at Wind Turbine Generator (WTG) location NNG-H17, within the boundaries of the Neart na Gaoithe (NnG) offshore wind farm area.

 

The equipment left in-situ reaches a maximum elevation of 38m above the seabed, which is approximately 12m below the level of Lowest Astronomical Tide (LAT).  There are low levels of third party vessel traffic within the boundaries of the wind farm, however, a Notice to Mariners has been issued advising of the seabed hazard, navigation warnings are being organised through UKHO, a guard vessel is at the location of the equipment and a 50m exclusion zone has been implemented.  Weather permitting, a guard vessel will remain at the location of the equipment, until recovery.  There is approximately 2.3m3 and 2.8m3 biodegradable oil encased within the equipment, however this is within a closed system and therefore will not leak whilst not operational. 

 

The deposit occurred during drilling and casing installation operations from the Saipem 7000 call sign: C6NO. The S7000 has departed the Neart na Gaoithe (NnG) offshore wind farm area, however the location of the item is marked by a Guard Vessel and an exclusion zone is implemented. Navigation warnings will be issued until the item is recovered.

Cable Fault - BritNed HVDC Cable

The second cable repair is completed, but possible exposed cable remains a hazard. Consequently, the safety zone is still in operation.

Following 2 recent faults (caused by impact damage) in the same area and subsequent repairs to the BritNed HVDC Interconnector, the latest completed on 07/06/21, the repaired section although trenched, is still in the process of natural backfill and areas of exposure remain. A guard vessel (currently M/V FORTUNA) remains on site. 

 

We wish to remind ship’s captains of the presence of subsea cables and request that extra caution is exercised when operating near charted cables in order to avoid any incident. Due to changing seabed conditions it should not be assumed that all cables are buried.

Construction of wind farm - Moray East

Due to the construction of the Moray East Offshore Wind Farm, there are several elements to this notice - safety zones; construction schedule; and buoy positions.

For background information about Moray East, please visit: www.morayoffshore.com/moray-east

 

Safety Zones

Please be advised that the Scottish Ministers have authorised the use of the safety zones during construction and operation of the Moray East Offshore Wind Farm as detailed below.

 

During construction

  • A 500 metre radius around each WTG and OSP where construction works are taking place that include sensitive activities being undertaken by vessels RAM. A maximum of three of such zones is permitted at any one time. 
  • A 50 metre radius around partially completed WTGs and OSPs where work is not underway and the risk assessments identify a need. 
  • A 50 metre radius around each completed WTG and OSP prior to commissioning and as required by a risk assessment process. 

During major maintenance

  • A 500 metre radius around all major maintenance works being undertaken around the WTGs and OSPs. No more than one major maintenance zone is permitted at any one time.

Construction Activities

It is currently anticipated that weather permitting offshore construction works will be carried out on a continuous basis (i.e. 24 hour working, seven days a week) unless notified otherwise.

 

Please be aware that by virtue of its mode of operation and the equipment deployed, construction vessels listed in the table below may be Restricted in their Ability to Manoeuvre as defined under COLREGS (International Regulations for Preventing Collisions at Sea 1972, Rule 3). Masters of vessels are therefore requested to maintain their vessels and gears at a minimum safe distance from these vessels of 500 metres when they are undertaking it work and showing the appropriate shapes and lights.  Further Notice to Mariners will be issued as construction progresses.

    Survey - Shetland HVDC Link/001

    NKT, on behalf of Scottish Hydro Electric Transmission (SHE Transmission), will be undertaking a geophysical survey of the Shetland HDVC link cable route between Noss Head north of Wick and Weisdale Voe in Shetland. Activities ongoing 27/05/21 - 08/07/21.

    The survey will be conducted using the Noordhoek Pathfinder and will involve the use of Multibeam Echosounder (MBES), Sidescan Sonar (SSS), Sub-Bottom profiler (SBP), Remotely Operated Vehicle (ROV), Unmanned Survey Vehicle (USV – nearshore Shetland only) and Magnetometer equipment, some of which will be towed sub-surface astern of the vessel. The Survey is being undertaken to enable the refinement of the cable route and the optimisation of trenching.

     

    The extent of the planned survey is -/+100m either side of the route centreline detailed in this notice.

     

    When using towed equipment, the total run-in length for Noordhoek Pathfinder is a minimum of 1200 m with a minimum turn radius of 320 m. As such, the vessel may at times be required to operate outwith the 200m wide survey area to facilitate survey line changes.

     

    A Surrogate Item Test (SIT) for the purpose of verifying the capabilities of the MBES, SSS and MagSense systems will be utilised. The SIT will be completed in the Northern or Southern location detailed in this notice, subject to weather. A target weighing approx. 50kg will be deployed on the seabed, attached to a clump weight and marked using a bright yellow surface buoy. The approx. area required for the work is 40m wide x 100m long, and the survey vessel will remain in the vicinity of the SIT for the duration of the exercise (4-6 hours). On completion, the target will be recovered.

     

    All vessels are required to comply with the COLREGS, especially rules 16 and 18 as the survey vessel will be restricted in her

    ability to manoeuvre.

    Deployment of Conical Buoy - Neart na Gaoithe OWF

    Neart na Gaoithe Offshore Wind Farm Limited (NnGOWL) have installed a conical marker buoy within the nearshore extent of the Export Cable Corridor.

    As part of the preparation works for cable installation in the nearshore area of Thorntonloch, two short trenches of approximately 800 metres (m) are currently being excavated for a section of each export cable, with the material temporarily being side cast. The height of the side cast material will temporarily reduce the navigable water depth by up to 1.5m, which, due to the shallow water depths in the nearshore area, is greater than 5% of the water depth in some areas. To notify maritime users of this temporary change, a conical marker buoy has been installed at the seaward extent where the reduction is no longer greater than 5%.

     

    The conical marker buoy installed is a SL B700, 1510mm in height and 700m diameter shown in Figure 2. The buoy has an interconnected mooring attached to a clump weight and an installed lantern. The lantern is emitting a yellow light with a character of flashing once every 5 seconds at a minimum range of 2 miles.

     

    Schedule The conical marking buoy will be in position until the temporary side cast material is backfilled and the water depth is no longer reduced. This is expected to be completed towards the end of July 2021.

    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. The approximate size of the tree with over trawl legs deployed is 7.8m x 7.8m x 6m high.

    Snagging Hazard - Dropped Object Weight 115kg

    Wireless telemetry basket containing measuring 1.4 m x 1.4 m and weighs 115 kg when submerged.

    As part of the initial drilling operations in 2019, the wellhead assembly was fitted with a cap containing a transponder for the relaying of monitoring data from downhole gauges and a basket was placed on the seabed adjacent to the well containing associated wireless telemetry equipment. 

     

    It has now been observed that both the cap and the basket are no longer present. 

     

    PFML are on location conducting an ROV based visual inspection of the suspended Well 205/26b-14 in the Lincoln field west of Shetland.  The Olympic Taurus arrived at the well location and deployed the ROV for inspection at the seabed.  On inspection neither the cap or basket were present.

     

    No instances of snagged fishing gear or other debris have been identified on the wellhead. 

     

    The risk is that trawled gear may snag on the basket and cause damage.  It is expected that he basket is too light to trap the vessel and cause any significant threat.  The cap is smaller, so there is a risk the nets may lift the cap to surface and cause a risk to personnel on the vessel.  However, as the cap is now off the wellhead, it is likely to be sitting flush with the seabed and is unlikely to be picked up by gear working in this area, as it is typically designed to bounce over the top of seabed obstacles (like the many boulders in the area). 

     

     

    The vessel and ROV has conducted a search around the well, 250 m x 250 m grid with 20m line spacing, and not identified the objects.

     

    PFML intend to go back to abandon the well this year, which would include an as left survey, so further efforts will be made then to locate and recover.  If not found, no other action will be taken.

    Lost CPT rod - Eastern Link 1

    During CPT operations a CPT rod broke and was lost to the seabed. The rod is made of steel and is 3.6cm in diameter. It is estimated that 0.75m of rod is protruding above the seabed.

    The cone and friction rod were also missing at recovery and are most likely curried under the seabed. These are also made of steel with the same diameter. The cone is 35cm long and the friction rod is 30cm long. 

     

    There may be a minor risk to trawler’s fishing gear if they trawl over this location, however, it is more likely that any trawling gear would break the rod below the seabed.

    Triton Knoll Offshore Wind Farm - Navigation Warning

    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.

    Mariners are advised that the remnants of a Wave Rider Buoy sinker weight and partial rigging remain in position at:

     

    Latitude Longitude Water Depth (LAT)
    53° 30.442N 000° 50.564E 19.7m

     

    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.

    ***Note *** 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.

    The 6th mattress for the Shell 34” pipeline will be recovered between 14th November - 31st January 2021 by the Seven Falcon. The Fleximat dimensions are 6.4m x 3.0m x 0.5m Weight in Air 15860kg.

    During overboarding of the 6th mattress for the Shell 34” pipeline, the crane wire parted when the matt was entering the splash zone at approx. 25m above seabed. The Fleximat dimensions are 6.4m x 3.0m x 0.5m Weight in Air 15860kg.

     

    The mat was being overboarded 15m away from the 34” pipeline, the mattress and frame landed on the seabed 6m away from the 34” pipeline

    • Fleximat 6.4x3.0x0.5m 2.4 & 3.2te/m3 Concrete Mattress – Weight in Air 15860kg
    • Mattress Lift frame – 6.3x2.4m – Weight in Air 1.7te
    • Approx. 25m Crane wire
    • 0.5t Crane Block

    25m Crane wire and 0.5te Crane Block safely recovered 13:50, 08/09/20.

     

    Plan is to recover mattress but inspections into the current state of the mattress are required to determine a suitable recovery methodology.

     

    A marine licence (ML/634) application has been submitted and approved by BEIS,  A variation to extend the marine licence to 14th November 2020 was approved by BEIS on 2nd November, and a second variation for extension to 31st January 2021 is now pending with BEIS.  This is due to scheduling delays due to poor weather.  The mattress frame and mattress will now be recovered by the Seven Falcon offshore support vessel.

    Exposed Pipelines - Scott Field

    Pipelines in CNOOC’s Scott field have experienced upheaval bucking. As a result, in three locations, pipelines are now exposed and present a significant snagging hazard. Sea users are strongly advised to avoid these locations.

    Detailed below, to avoid hazardous interaction with these sections of exposed pipeline, pending the execution of mitigation works.

    Dropped Object - Hornsea Two Offshore Wind Farm

    Noise monitoring frame(steel 1m3 frame approx. 40kg), hydrophone,riser buoy,clumped(100kg chain clump weight) & 50m Dyneema riser line(dia.~25 mm)remain after the riser line was severed below the surface buoy.Surface marker buoy and pellet buoy recovered.

    The riser line was severed below the surface buoy and it has not been possible to recover the items. Investigations as to the cause of the loss are ongoing.

     

    Possible risk of entanglement from remaining riser line.

     

    The SONAR imagery acquired during the recovery attempt indicated the riser line (the main aspect of concern) to be still attached to the anchor weight and suspended in the lower part of the water column. Given the elapsed time, the line will be fully saturated and neutrally buoyant and fully submerged. It is anticipated that the action of tidal currents on the line will cause it to knock down and eventually become entangled in the frame and other gear. Whilst it has not been confirmed, it is unlikely that the line would remain close to the surface.
