Partnership: Equinor
Market: Wind Farms-Offshore
Equinor (former Statoil) awarded Nexans the contract to supply static and dynamic cabling and associated accessories for the world’s first floating wind farm, following a successful demo facilitated by Nexans’ cables which have been in operation since 2009.
Following the initial Norway demo, Equinor awarded Nexans a new contract worth approximately 10.2 million Euro to service the Hywind Scotland Pilot Park wind farm. Nexans delivered offshore export cables to the site, located 30 km off the coast of Aberdeenshire.
The offshore cable systems was tested, sealed off, prepared for pull-in and delivered in individual lengths ready for installation. The cables were tested and manufactured at Nexans’ specialized facility in Halden, Norway.
The pilot 30MW floating farm is made up of five wind turbine generators connected through an inter-array cable network before feeding into a single offshore export cables carrying energy back to land in Peterhead, Scotland. Following the successful Norway demo, the project, assisted by Nexans, will demonstrate technological improvements, installation and operation of multiple floating wind turbines, as well as examine the cost efficiency of the park configuration.
Hywind Project – Copyright STATOIL – Wind Farms Offshore
The Hywind project will generate energy to power roughly 20,000 homes, and will lead the way to developing larger floating wind farms in other areas after an initial two-year testing period.
Vincent Desale, Nexans SEVP for the Subsea and Land System Business Group commented “ This project is a great example of Nexans pioneering alternative offshore wind design, extending the options for renewable energy generation. The contract establishes Nexans as leaders in offshore wind innovation by designing specialist cables for both the initial pilot project and the Hywind Pilot Park. ”

Nexans Power Export Cable Supplier For The Seagreen Offshore Wind Farm Project
Seagreen Offshore Wind Farm Project
Location: Scotland
Partnership: SSE Renewables
Market: Wind Farms-Offshore
Nexans is SSE’s preferred supplier for the design, manufacture and installation of the onshore and offshore export cables for the 1,075MW Seagreen wind farm project. Nexans will supply and install three 65 km offshore export cables and three 20 km onshore export cables.
Phase 1 development, comprising the Seagreen Alpha and Bravo wind farms. It will have combined capacity of 1,075MW. When complete it will form the largest windfarm project in Scotland when they come online in 2024. To promote contract opportunities for local companies, SSE Renewables organises ‘Meet the Buyer’ events, where they can discuss their service offerings with members of the supply chain.
Seagreen Project Director John Hill said: “We are pleased to announce Nexans as our preferred supplier to design, supply and install the onshore and offshore export cable. Nexans is one world leaders in this field and this agreement is a major step forward for the Seagreen project.”
The Seagreen Offshore Wind Farm project is located 27km off the coast of Angus in the North Sea.
A joint venture between TotalEnergies (51%) and SSE Renewables (49%), Seagreen will be Scotland’s largest and the world’s deepest offshore wind farm when complete.
The Seagreen offshore wind farm was consented with permission granted to install 150 offshore wind turbines.
114 offshore wind turbines are currently under construction with an installed capacity of 1,075MW and will be fully operational by early 2023. The power generated will be exported to the grid via a new substation at Tealing near Dundee.
The 114 Seagreen wind turbines will provide enough green energy to power more than 1.6 million homes, equivalent to two-thirds of all Scottish homes. They will also displace over 2 million tonnes of carbon dioxide from electricity generated by fossil fuels every year – similar to removing more than a third of all of Scotland’s annual car emissions and making a significant contribution to Scotland’s net-zero ambition by 2045*.
The remaining 36 offshore wind turbines are consented but not yet constructed. The power will be exported to the grid via Cockenzie, East Lothian.
In January 2022 Seagreen submitted a Screening Report to Marine Scotland to increase the size of the 36 consented turbines.

Arc Flash Risk
Special thanks to Engineering Power Solutions for the kind permission to republish
Arc flashes pose a significant hazard to electrical systems operatives. They can cause damage to equipment as well as severe injury or even death to personnel. However, with proper arc flash safety procedures in place it is possible to reduce the risk significantly.
An arc flash is a sudden discharge of energy, connecting a component through the air to the ground or to another voltage phase in the same system. This can be the result of loose connections, exposed live parts or other short circuits in faulty equipment. Careless work practices can also cause arc flashes when working on live electrical systems.
The resulting explosions produce highly dangerous intensities of heat and light.
As well as damage to electrical equipment, arc flashes can cause internal and external burns, eye injuries from intense UV light emissions, and lung damage from hot gasses or vaporised metals.
Given these hazards, it would seem vital to know how to prevent arc flashes. Yet aside from simply powering down a system, it is virtually impossible to eliminate the hazards entirely. However, it is possible to mitigate the risks, and what’s more, it is an employer’s legal duty to carry out appropriate assessments to do so.
Here are five ways to minimise the dangers posed by arc flashes.
1) Power Down Electrical Equipment Where Possible
An arc flash can only occur with live voltage, so the simplest hazard mitigation strategy is to power down the system when not in use. It should always be assumed that a system is live until it has been verified as de-energised. However, it is not always possible to carry out work on de-energised electrical equipment, and in these cases, other safety measures must be taken.
2) Ensure Safe Working Systems
A full arc flash risk assessment should be carried out on all electrical systems. It need only be conducted once in full but should be reviewed at least every five years. Reviews should also be carried out if any components are changed or other system updates are made. A professional risk assessment identifies the potential hazards in an electrical system, so that they may be properly labelled, and the risks mitigated.
3) Wear PPE
When engaging with electrical systems, workers should wear the appropriate personal protective equipment (PPE). Insulated rubberised gloves give protection against electrical arcs, as well as heat and flame resistance. Head and face gear is also important to protect against high heat and light intensities, as well as impact damage from an arc flash explosion.
4) Keep a Safe Distance
Arc flashes can cause injuries at distances of up to six metres. Operators should maintain a safe distance from points of severe hazard, using remote tools or robots, as well as wearing appropriate PPE when within the calculated arc flash boundary.
5) Ensure Proper Training
Anybody working with electrical systems needs the appropriate training to understand the hazards and the requirements for safe working. This is even more important if engagement with live systems is unavoidable. Operatives need to know how to conduct a risk assessment before starting work, identifying hazardous points in the system and the appropriate working practices to mitigate them.

This is the question arc flash specialist protective clothing manufacturer, ProGARM, is asking the UK industry. The question has been posed as part of a national campaign to raise awareness around the often-fatal risk of arc flash injury.
The campaign sees ProGARM calling on workers at all levels within the rail, construction, petrochemical, utilities, power generation and industrial electrical industry to share their experiences in a bid to capture a true picture of the real risk of arc flash across the UK.
