Greater Gabbard offshore wind farm sits off the coast of Suffolk and consists of 140 wind turbines manufactured by Siemens .

The wind farm is capable of generating up to 90MW (megawatts) of clean, environmentally sustainable electricity. This is enough power for

approximately 80,000 homes with three 45km long export cables bringing power onshore

An Advisory Safety Zone of 50m around each turbine and substation structure is requested. An 200m anchorage exclusion zone around the export cable is requested. All vessels are asked

to respect the Advisory Safety Zones, which as well as reducing the risk of collision damage, will provide protection to vessels, the export cable, and wind turbine structures.

If any major maintenance works are planned, Notices to Mariners will be promulgated in advance as required. During such works a Mandatory Safety Zone of 500m is likely to apply to

certain turbines and/or vessels.

Advisory Safety Zones

Reducing the Risks whilst Fishing

To reduce the risks of fishing near offshore structures, it is essential to be up to

date with KIS-ORCA information. KIS-ORCA information is easy to install on your

vessel’s fishing plotter and ensures skippers are able to make informed decisions

for their safety.

The closer to the surface a subsea cable is lifted when fouled by fishing gear, the

more danger there is to the fishing vessel. In the interests of fishing safety and to

prevent damage to subsea structures, fishermen are advised to exercise caution

when fishing in the vicinity of subsea cables and renewable energy structures.

Loss of gear, fishing time and catch can result if a trawler snags a subsea

structure and there is serious risk of loss of life.

Emergency Procedures

If you suspect you have snagged a subsea cable, DO NOT

endanger your vessel and crew by attempting to recover

your gear.

Carefully plot your vessel’s position as accurately as

possible.

Advise the Coastguard of your situation, and call the

24 hour Emergency Number and state that an

incident is occurring concerning a subsea cable.

Dangers of Renewable Energy

Structures & Cables to Fishing

Renewable Energy Structures and Subsea Cables are a hazard

and fishing over them should be avoided at all times. Heavily

armoured cables used within the subsea cable and renewable

energy industry are very strong and have high breaking strains,

sometimes over 70 tonnes and can do extensive damage before

they give way. Most modern subsea cables carry high voltages

which could prove lethal if attempts are made to cut them.

Fibre Optic cable consists of an inner optical core encased within

a copper clad high tensile steel wire rope insulated with polythene.

In water less than 1500 meters deep, protection is added against

fishing and anchor damage in the form of external steel wire

armour. Due to the severe environmental demands placed on

submarine cables, a lead-alloy sheath is often specified because

of its compressibility, flexibility and resistance to moisture and

corrosion. The sheath is usually covered by a number of outer

layers, comprising a PE or PVC jacket and metal wire armouring.

The Kingfisher Information Service - Offshore Renewable & Cable

Awareness project (KIS-ORCA) is a joint initiative between

Subsea Cables UK and RenewableUK and is being managed by

the Kingfisher Information Service of Seafish.

The KIS-ORCA Project

Wind Turbines and Foundations

As wind turbines get larger and are

deployed in deeper waters, a range of

different foundation types may be

encountered such as monopole,

jacket, gravity base and suction

bucket. In some cases multiple

foundation types may be used within

a single site. In all cases it is likely

that scour holes will form around the

foundation base, the depth and extent

being dependent upon a range of

factors including seabed type and

current strength and direction. Scour

protection in the form of rock dumping

or cable mattresses is often used

around the base of the foundations

which may present a snagging risk.

During the operational phase of a

wind farm, an operator may request a

50m advisory safety zone around

each structure.

The inter array cables interconnect

the turbines typically in radial strings

going to the offshore substation

platform. The issues associated with

these are largely the same as per

cable burial. Each turbine will usually

have up to two cables entering the

foundation structure at the seabed

through a protective tube. Typically

the tube end has a bellmouth at the

seabed to aid alignment and pulling in

of the cables. Whilst the cables may

have been jetted in or ploughed as

close as practical to the foundation,

cables may not be fully buried and

may also become exposed by scour

holes forming. In these circumstances

scour protection in the form of rock

dumping or cable mattresses may be

used. Cables,albeit close to the

foundation, may present a snagging

risk to anchors and/or trawled gear.

Inter Array Wind Farm Cabling

To reduce the risks of fishing near offshore structures, it is essential to be up to date with KIS-ORCA infomation.

KIS-ORCA information is easy to install on your vessel’s fishing plotter and ensures skippers are able to make

informed decisions for their safety.

Reducing the Risks whilst Fishing

The closer to the surface a subsea cable is lifted when fouled by

fishing gear, the more danger there is to the fishing vessel. In the

interests of fishing safety and to prevent damage to subsea

structures, fishermen are advised to exercise caution when fishing

in the vicinity of subsea cables and renewable energy structures.

Loss of gear, fishing time and catch can result if a trawler snags a

subsea structure and there is serious risk of loss of life.

If it is thought prudent to slip, or cut your fishing gear in an attempt

to clear a subsea structure, always lower the gear to the seabed

first. Never attempt to slip anything bearing excessive weight.

Claims for loss of gear should be made to the appropriate authority

within 24 hours of arrival in port. Full particulars of the incident

should be given and full details recorded in the vessel’s official log,

date and exact time, the vessel’s position (VMS if suitable), depth

of water and a description of the

cable if sighted.

Claims for loss will only be considered if

current KIS-ORCA data is installed on your

vessel’s fishing plotter.

Offshore wind farms, renewable

energy structures and subsea

cables are increasing in number

around the shores of the UK. The

potential risks these structures may

cause to fishermen is significant and

the KIS-ORCA project aims to

ensure these are managed in a

responsible way.

It is against the law to wilfully

damage a subsea

cable. To enable fishermen to

continue to work safely in the

vicinity of subsea cables and

renewable energy structures, KIS-

ORCA provides fishermen with

information and accurate positions

of all these offshore structures.

KIS-ORCA information is made

available as fishing

plotter files and awareness charts

for use on vessels and on www.kis-

orca.eu, where information may be

viewed and downloaded.
