Show PageEmergency Contact Numbers
The numbers below are the emergency contact numbers for Subsea Cables and Renewable Energy Structures. These phone numbers relate to each offshore structure and may be used in case of an emergency, or urgent situation.
Show PageEmergency Procedures
Please keep clear of and do not damage subsea cables/structures. You risk the loss of your gear and catch, and international communications can be disrupted. These cables carry high voltages and can be dangerous to life. Many cables have high breaking strains, some over 70 tonnes. Cables will usually lie buried in the seabed, although because the seabed can move, there is no guarantee they will remain in the same place.
Show PageReducing Risks Whilst Fishing
It is essential to be aware of the locations of subsea cables and renewable energy infrastructure, when fishing in the vicinity of such structures. It is essential you have all the information in relation to their positions available to you and the KIS-ORCA project is designed to provide exactly that for all seabed users. Charts, fishing plotter files and an interactive map, showing subsea cables and renewable energy structures surrounding the UK, may be viewed or downloaded, free of charge.
Show PageThe Risks of Fishing near Cables & Renewable Energy Structures
The potential risks associated with the offshore renewable and subsea cable industries come in two distinct categories - surface structures and subsurface structures. Each type of structure may potentially be a risk to fishing activities. The information below describes these hazards, with the subsequent sections explaining the emergency procedures.

Show PageTidal Device Principles
Tidal devices exploit kinetic energy in the tidal flow of water caused by the interaction of the gravitational fields of the earth, moon and sun. Tidal currents are magnified by topographical features, such as headlands, inlets and straits, or sea bed channels. Many of the devices that use these currents are broadly similar to submerged wind turbines. Sea water is around 800 times denser than air but average flow speeds for viable projects are of the order of one fifth of corresponding wind speeds, giving a power density of around 5-10 times. This means that for a tidal device of the same rating as a wind turbine, the rotor will be smaller. Individual tidal devices are unlikely to reach the same rated power as offshore wind turbines; however, as to have sufficient space to deploy such large devices requires development of deeper water sites that generally have less significant tidal flows. EMEC has identified four main types of tidal energy convertors that are outline below.
Show PageWave Device Principles
Waves are created by the interaction of wind with the surface of the sea, sometimes over very long distances. The size of the waves is influenced by wind, the local seabed bathymetry (which can focus or disperse the energy of the waves) and currents. Waves offer a large source of energy which can be converted into electricity by a wave energy converter (WEC). Some wave energy converters have been developed to extract energy from the shoreline, others from waters offshore, some with a hydraulic power take-off system and some with an electrical power take-off system. EMEC has identified six main types of wave energy converter that are outlined below.
Show PageWave & Tidal Devices – Overview
The United Kingdom's wave and tidal stream energy industry is the current global leader, with more installed capacity than the rest of the world combined. Our strength has been built on established British marine engineering skills, the creation of world-first testing facilities and the strength of the energy resource found in UK waters. The UK is proud to have developed the first commercial scale wave and tidal stream projects in 1998 and 2003 respectively but the industry is now on the cusp of commercial viability as we move through the phases of development.

Once a developer has obtained a lease from the Crown Estate they will start to appraise the zone or lease area. This requires a number of surveys to be completed including boat or aerial based bird and marine mammals surveys, benthic grabs and fish surveys.
Show PageWind Farms – Design of Structures Installed
Offshore wind farms consist of a number of connected elements. These include the turbines, foundations, array cables, offshore substation, export cable and onshore substation and infrastructure. These items are installed using a range of different vessels and then serviced by either smaller crew transfer vessels or helicopters.
Show PageWindfarms - Overview
Offshore wind farms consist of a number of wind turbines which sit on foundations, secured to the seafloor, which produce electricity. This electricity is transmitted to where it is needed through a series of cables and substations. The first offshore wind farm was installed in Denmark in 1991 and the industry has grown rapidly since then with 3.3GW installed across Europe (1.8GW of which is in the UK). China, US, Japan and South Korea have also started to develop offshore wind farms.

Show PageThe Future of Subsea Cables
Subsea telecommunication cables have a very long history. Since the installation of the world's first submarine cable across the Dover Strait in 1850, Subsea cables have been essential to the worlds communications infrastructure.
Show PageSubmarine Cable Maintenance
Under a Cable Maintenance Agreement and on notification from a Maintenance Authority, a cable repair ship operator will mobilise one of its vessels to conduct a repair on a subsea cable. The maintenance authority will provide an estimated position of the cable fault based on tests carried out from the cable Terminal Stations located either end of the marine cable. Permitting, Charting, and existing cable information is assessed prior to the vessel departing.
Show PageMaintenance / Repair Operations
Submarine cables are very reliable, however, there are occasions when a repair to a cable becomes necessary.
Show PageCable Burial
At the planning and installation phase of a submarine cable project one of the most effective methods of protecting a submarine cable from damage caused by external aggression is to bury the cable, usually with a sea plough.
Show PageInstallation Procedures and Methods
Selection of provisional route
Once the requirement for a cable system has been identified and funds raised to build it, the first thing which happens is that a cable manufacturer and installer is contracted by the cable system parties.
Show PageDesign
Modern Fibre optic cables can carry many millions of telephone calls, together with huge amounts of video and internet data. Approximately 95% of the world's telecommunication requirements are met by submarine cables. Cables are used because of their high reliability, capacity and security. Cables have an insignificant delay compared to satellite and are most cost-effective on major routes, hence communications costs are cheaper than satellites.
Show PageAbout
The KIS-ORCA Project The Kingfisher Information Service - Offshore Renewable & Cable Awareness project (KIS-ORCA) is a joint initiative between the European Subsea Cables Association (ESCA) and the Kingfisher Information Service of Seafish. ESCA membership represents much of the subsea telecommunications and offshore renewable energy industry and they work with industry bodies like Renewable UK who recognise the benefit and value of the KIS-ORCA project.
The aim of the KIS-ORCA project is to provide fishermen with accurate, up to date and free information relating to subsea cables and offshore renewable energy structures across Europe.
KIS-ORCA information is available to fishermen in the following formats:
Fishing Plotter Files
Supplied on USB stick, all the KIS-ORCA data is available to fishermen in the most popular fishing plotter system formats and is updated annually. These files are also available to download from here.
Awareness Charts
Awareness charts are produced for key KIS-ORCA data areas. There are six charts surrounding the UK and localised charts for each constructed wind farm. These are available to download from here.
www.KIS-ORCA.org
This interactive website allows fishermen to view subsea cable and renewable energy structures on an interactive map, download the latest data and ensure they are up-to-date with the very latest offshore activity news. The website has been produced primarily for Fishing Safety, although also gives fishermen an insight into the offshore industries they share the seabed with.

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 |

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.

See detailed map on our bulletin websitePossible 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.

Show MoreApplication for Offshore Development Area - Seagull Umbilical
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 tieâ€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.
