Emergency 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.

Reducing 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.

The 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.

Tidal 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 Page

Wave 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.

Wave & 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.

Wind Farms – Installation Methods

Life cycle stages

Lease award and Pre-construction

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.

Wind 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 Page

Windfarms - 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.

The 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 Page

Submarine 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 Page

Maintenance / Repair Operations

Submarine cables are very reliable, however, there are occasions when a repair to a cable becomes necessary.

Show Page

Cable 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 Page

Installation 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 Page

Design

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.

About

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.eu 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.

Deployment of Construction Buoyage - Neart na Gaoithe

Neart na Gaoithe Offshore Wind Limited (NnGOWL) will be deploying nine construction marker buoys around the Neart na Gaoithe Offshore Wind Farm site. The marker buoys will remain in place until after construction of the Offshore Wind Farm is complete.

The earliest commencement date for marker buoy deployment will be 24 February 2020, the duration of deployment is anticipated to last up to 8 days. A steel chain will be connected to each marker buoy, and the chain will be present through the water column, connected to an anchor placed on the seabed.

 

Masters of vessels are therefore requested to maintain their vessels at a minimum safe distance from the vessel of 500 metres when it is undertaking its work. A guard vessel will be present offshore at all times, either the Artemis or Seagull.

Power Cable Replacement - Carsaig to Jura (Lealt Bay)

Briggs Marine Contractors (on behalf of SHEPD) will be undertaking a cable installation within a 1km wide corridor between Mainland (Carsaig) and shoreline of Jura.

The work will utilise the DP2 cable laying vessel ‘M/V Elektron’ Call Sign: LADO, Dive Vessel ‘Forth Warrior’ Call Sign: 2JHR8 and support craft vessels ‘Celtic Trader, Celtic Voyager, Celtic Nomad and Celtic Guardian’.

 

The Forth Trojan will operate as a guard vessel during cable lay operations

 

The installation work aims to be concentrated within the existing cable route corridor, defined by the following coordinates. Due to weather, these operations have been delayed and will commence during an appropriate weather window following 10/02/2020 and will continue over a planned period of 7 days, weather permitting.

 

The installation work aims to be concentrated within the existing cable route corridor, defined by the following coordinates. However, some work will take place within the central channel.

 

 

Work Description

Cable installation will be completed by Elektron, during which time it will be assisted by Forth Warrior and support craft Celtic Trader, Celtic Voyager, Celtic Nomad and Celtic Guardian. Cable lay operations will be conducted on a 24 hour basis.

 

Other vessels should maintain an appropriate and safe distance of 500 m when passing the vessels whilst operational and should pass at the lowest possible speed to avoid vessel wash effects. Vessels will be working throughout 24 hours and will display appropriate day shapes and lights during reduced visibility and night operations.

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 yearâ€Âround and 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, the MV Apollo and the MV Normand Service will 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.

Breagh Pipelines - Exposed Fibre Optic Cable

The Breagh fibre optic cable (PL2770) is exposed on the seabed along various stages of the route between Redcar and the Breagh A platform.

A scallop dredger became snagged on an exposed section of the fibre optic cable in June 2019 causing serious damage to the fibre optic cable and subsequently had to abandon retrieval of his gear for safety reasons.  This notification is made to the fishermen, operating between Redcar and the Breagh A platform, to be advised that the fibre optic cable represents a serious snag risk to both scallop dredgers and static gear fishing in the vicinity of the line.

 

Fishermen are advised to stay away from the line to avoid the risk of becoming snagged on the unburied sections of cable.

Exposed Export Cable (Beatrice Wind Farm)

During a routine inspection of the export cable EC2, a short section of the cable was found to be partially exposed on the Seabed. This may constitute a hazard to activities such as fishing and anchoring.

A short area (4metres) of partial exposure of Export Cable EC2 is in the vicinity of the mid cable joint at the location where the cable changes direction through 180 degrees.

 

The maximum exposure observed was approx. 50% with no damage or defects observed. The seabed at location was observed to be flat and featureless and mainly consisted of sand and silt. It is requested that mariners avoid activities which are likely to disturb the seabed within a 500m Radius of this location until the exposed cable has been re-buried. A further Notice to Mariners will be issued to confirm the re-burial and safe operation in this area.
