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.

Survey - Sofia Offshore Wind Farm

Fugro continue with Offshore Site Investigations along the export cable corridor of the Sofia Offshore Wind Farm (SOWF), with works expect to run until July 2020.

Fugro continue to undertake Geotechnical Investigations at the nearshore area of the SOWF export cable corridor using the Jack Up Barge 'Haven Seariser'.  Operations commenced on the 26th June are expected to run through to the end of July 2020.

 

Due to geotechnical vessels having limited manoeuvrability whist working in DP mode, it is requested that all vessels operating within this area maintain a safe operational distance, in line with standard procedures i.e. a C.P.A of 500 m, which is included in the survey area buffer of 2,000 m (coordinates below).  Geotechnical operations will be undertaken on a 24 hour basis, with a crew transfer vessel operating twice a day to and from the Jack Up Barge 'Haven Seariser'

 

All survey durations are dependent on prevailing weather conditions and work progress.

 

The guard vessel ‘Margaret Mary’ will provide additional support on site where necessary.  All vessels can be contacted on VHF channel 16 throughout the works for any further information.

 

The following vessels will be operational on site during these works;

Surveys - Norfolk Vanguard & Norfolk Boreas Windfarms

MMT have been contracted by Vattenfall Windpower Ltd to perform survey for the planned transmission assets linking the Norfolk Vanguard (NV) and Norfolk Boreas (NB) windfarm areas to shore.

Project Description and Survey tasks

During this survey the vessel will be deploying underwater survey equipment. During such times the survey vessels may have restricted ability to manoeuvre and other vessels are requested to pass at a safe speed and distance (at least 500 m). The vessels will monitor VHF Channel 16 at all times.

 

Geophysical survey with towed equipment will be performed along export cables and at Offshore Sub Stations (OSS). Equipment to be used: singlebeam echosounder (SBES), multibeam echosounder (MBES), side scan sonar (SSS), magnetometer (MAG) and sub bottom profiler (SBP). The scope will also include an environmental survey to map the presence of Sabellaria in the Haisborough, Hammond and Winterton (HHW) Special Area of Conservation (SAC). This shall also entail geophysical surveys using singlebeam echosounder (SBES), multibeam echosounder (MBES), side scan sonar (SSS) within the HHW SAC area, additionally targeted sediment sampling and/or environmental mapping using a Drop Down Video system at yet to be determined positions will be completed.

 

Timeline

Survey works will commence on the 2nd June and is scheduled to end at the 14th August (subject to change, ultimately dependent on the weather situation). Survey works will initially be carried out in blocks 1 and 2 and then move to blocks 3 and 4 on the 6th of June and then continue from west to east for the remainder of the period. Nearshore survey is scheduled to commence on the 28th of June and end in the end of June.

Vessel “Havila Phoenix” will be undertaking operations to bury these three subsea power cables below the seabed, via means of remotely operated trenching vehicles. Cable laying is expected to be completed by circa 3rd October 2020. Cable trenching is expected to be ongoing until early November but will be followed by a separate campaign to install remedial protection over the cables on any remaining unburied/unprotected sections. Details on remedial campaign(s) will be provided nearer the time of execution. The above dates include some weather contingency, however the operations may be subject to further extension.

 

Please be aware that by virtue of its mode of operation the NKT Victoria and Havila Phoenix will be Restricted in their Ability to Manoeuvre (RAM) 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 the vessel of 500 metres when it is undertaking work and showing the appropriate shapes and lights in accordance with COLREGs Rule 18.

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.

Diving Campaign near Boyndie Bay

As part of the three export power cable installations for Moray East Offshore Wind Farm, Moray East and their contractor NKT intend to undertake diving works near Boyndie Bay

The above mentioned works includes the preparation works on the HDD duct (offshore) exit, cable installation support works, and post-cable installation grouting and finishing works for the project. Work on the duct and surrounding area will be undertaken by divers connected to diving support vessel “MV C-Fenna” operated by Leask Marine. During diving operations this vessel will be positioned via a four-point anchor mooring spread. Also active during this time will be a crew transfer vessel assisting operations, and transferring personnel will be the MV “C-Spartan”, also operated by Leask Marine. For diving vessel moorings, for the avoidance of any fishing gear or buoyed items posing risk of wire entanglement based on anchor positions, these are marked on the drawing below. Moray East intends to commence diving preparation works on the 6 th of July 2020, for the duct preparation works, and continue diving works on all three cables for installation support, and postinstallation grouting and finishing works. This diving campaign is expected to reach completion circa 18th October 2020. The above dates include some estimated/expected weather delays, however, this activity may be subject to further extension of works.

 

Please be aware that by virtue of its mode of operation the C-Fenna and C-Spartan will be Restricted in their Ability to Manoeuvre (RAM) 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 the vessel of 500 metres when it is undertaking work and showing the appropriate shapes and lights in accordance with COLREGs Rule 18.

UXO Disposal (Detonation) Operations - Viking Link HVDC Cable

Remotely Operated Vehicle (ROV) disposal operations of confirmed Unexploded Ordnance UXO (cUXO) of the Viking Link interconnector cable.The Noordhoek Pathfinder will be completing confirmed UXO operations in UK waters,on 29th June 2020 for 3 weeks.

During the same period bubble curtain operations will be executed by the vessel Noortruck. The vessel will deploy a bubble curtain around the confirmed UXO’s to reduce the noise levels under water.

 

National Grid Interconnector Holdings Ltd. and Energinet.dk (joint venture of Viking Link) have contracted N-Sea Survey B.V to complete an inspection, detection and clearance campaign of potential Unexploded Ordnance (pUXO) in relation to the installation of the HVDC electrical interconnector cable between Great Britain and Denmark. The cable is known as ‘Viking Link’. As well as making landfall in the UK and Denmark, it crosses the territorial waters of the Netherlands and Germany. The cable will terminate on the east coast of England, approximately 2 km north of the village of Anderby Creek.

The Noordhoek Pathfinder survey vessel shall dispose previously identified confirmed UXO by detonation along the route during daylight hours. This will be conducted using a static ROV. Operations will be supported by a bubble curtain deployed from the vessel Noortruck. We kindly ask that all vessels in the local vicinity observe a 2000m stand-off at all times, and no fishing gear within 500m of each target location stated below.

During the disposal operations, the vessels will display the prescribed lights and signals for operations and will be monitoring VHF Channels 16 and 12.

Unsuccessful clearance activities at some of the confirmed Unexploded Ordnance (UXO) items, further UXOs have been relocated to date within the Neart na Gaoithe (NnG) Offshore Wind Farm and Export Cable Corridor.

 

These UXO items either do not contain a fuse or are confirmed as solid shots and clearance by detonation is not likely to be possible. As such, relocation of the item is necessary. The item will be relocated to a position outwith the construction areas, but within the boundaries of the NnG licensed area, as permitted by the Marine Licence.

Cable Installation - Penguins (UK) - Snorre A (NOR)

Tampnet AS will in the period 1st of July until 30th of August 2020 perform an installation of a 90 km Submarine Fibre Optical Cable route between the Penguins Field and the Snorre field in the North

The cable will initially be surface laid and then buried, by means of trencher and cutting tools to ensure protection. In the time between the cable lay and burial the cable will be exposed until the burial operations are completed.

We advise that no fishing activity / trawling or using bottom gear in proximity to these areas must occur and to manoeuvre with caution to avoid damage to fishing gear or cable.

 

Deep Ocean will install the cable for Tampnet. Two vessels will be used in the operation:

  • Maersk Connector  Call Sign: OWEB2
  • Havila Phoenix  Call Sign: C6BD2

In addition we will use guard vessels to prevent damage to the exposed cable before burial is performed.

Cable Repair - GTT Segment C

Following cable repair, cable exposed due rocky seabed conditions

Notice to fisheries and seabed users in the Irish Sea:

 

Please be advised that following a recent cable repair to the GTT (Hibernia) Segment ‘C’ between Southport and Dublin, the cable has been deployed as follows:

 

Initial Splice:        53° 48.3613’N    04° 30.1514’W

Standing bight:   53° 48.2208’N    04° 29.4494’W

Final Splice:         53° 48.1279’N    04° 28.2360’W

 

It should be noted that throughout the extent of the cable repair, despite repeated attempts at post lay burial by an ROV, the predominantly very rocky seabed has meant that cable burial and hence protection has not been possible.

 

It should also be noted that at the position of the ‘standing bight’ the cable is standing upright from the seabed at a height of 0.4 metres, with a length over the ground of 2.0 metres.

 

All seabed users are requested not to deploy equipment which engages with the seabed in this area, to avoid snagging of the cable and particularly so, at the standing bight area.

 

In case of any issues, please do not hesitate to contact the GTT Hibernia emergency contact number on: +353 1 867 3600 Option 2

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.
