We have answered some of the most common questions about offshore wind farms in the section below, but we will be adding new questions as they arrive through our community consultation process and they will be published here regularly, so please check back in. We are happy to discuss the project so if you do have any questions, please feel free to Contact Us
An offshore wind farm consists of a number of large wind turbines that are fixed to the seabed. A turbine generates renewable electricity when the wind turns its blades. A floating offshore wind farm utilized floating platforms to support the wind turbines. This means that the siting is more flexible and that ultimately the structures can be removed more easily in the future.
The electricity generated by each turbine may be collected by an offshore electricity substation located within the wind farm or cabled directly to shore. Seabed cables connect the substation to the coast. These cables transport the electricity to land from where it will be used to power homes, farms and businesses around Ireland.
Where once the benefits of offshore wind were inaccessible to Northern Ireland, due to the deep waters and challenging seabed, floating wind now presents the opportunity to help decarbonise the economy, contribute towards energy security and bring the benefits of offshore wind supply chain to the region.
We are keen to co-exist with other users of the sea.
In GB, the government has powers to declare ‘safety zones’ around offshore wind developments typically during construction, for major maintenance works and for decommissioning, to preserve the safety of other users of the marine environment and the development itself. Once wind farms are fully constructed and operating normally safety zones are only approved if there is a clear justification for their implementation. The NI Department for the Economy has recently consulted on the creation of similar powers in NI waters.
For North Channel Wind navigational safety will be of principal concern when considering whether any safety zones are needed around the turbines, and we will be undertaking a thorough Navigational Risk Assessment for the project in keeping with Marine Guidance Note (MGN) 654. This will involve consultation with the Maritime and Coastguard Agency (MCA) and other commercial and recreational marine stakeholders.
The minimum clearance between the blade tip and the sea would be at least 22m above sea level.
North Channel Wind has ongoing engagement with the fishing industry, and has also met with various recreational boating stakeholders including the NI branch of the Royal Yachting Association, the Cruising Association, Berth Holders Association members in Glenarm and Mid & East Antrim Council Harbour and Marinas Manager. We will continue to engage with these stakeholders as the project progresses.
Absolutely, NCW is committed to maximising the benefit to Northern Ireland and to work with local companies to ensure high levels of local content in the projects going forward.

Wind energy is Northern Ireland’s main tool in the fight against climate change. It cuts our carbon emissions by millions of tonnes every year and currently provides almost half of the country’s electricity.
However, almost all of Northern Ireland’s existing wind farms are onshore. Wind conditions off the coast are far better and much taller turbines can be used. This means a single offshore wind turbine can generate as much as three or even four onshore turbines.
The Northern Ireland Executive has committed to a target of 80% of electricity generation from renewables by 2030 and a trajectory to a net zero economy. The Energy Strategy and associated action plan which was published in January 2022 announced an aspiration for Northern Ireland to develop 1GW of offshore wind as part of the wider net zero aspiration. Developing offshore wind energy is essential if we are to reduce Northern Ireland’s carbon emissions and to play our part in the fight against climate change.

Generally, there is no reason why fishing activity and offshore wind farms cannot co-exist although sometimes fishing practices may need to be amended slightly to ensure that the two industries can work together to ensure the space is shared safely and to mutual benefit. Fishing continues today near offshore wind farms in many parts of the world.
It is important for the developer to engage as early as possible with the local fishing community to ensure ways are found to minimise the impact of a wind farm on fishing.
Every project is unique and there are many different types of fishing activity. The best way to ensure fishing can continue around an offshore wind farm is for the developer and local fishers to share information and work together to try to overcome obstacles.

BVG Associates have created a Guide to a Floating Offshore Wind Farm, with funding from the Offshore Renewable Energy Catapult, The Crown Estate and The Crown Estate Scotland. The guide has been developed to educate its users about the different lifecycle activities, components, costs and supply chain of floating offshore wind.
