'Hornsea 3 Offshore Wind Farm Abnormal Load Movements' Announcement received as follows:
I am writing to you on behalf of Ørsted in relation to the Hornsea 3 Offshore Wind Farm to inform you of upcoming abnormal load movements scheduled to pass through your area in the coming months.
About Hornsea 3
The Hornsea 3 Offshore Wind Farm received development consent in December 2020. Hornsea 3, once complete, could provide clean power to over three million UK homes and will make a significant contribution towards the UK meeting its net zero commitments. We are committed to working closely with stakeholders and local communities to ensure we deliver this project as collaboratively and efficiently as possible.
Abnormal Load Movements
Our transformer installation activities involve the transportation of abnormal loads, meaning they are either larger, heavier, or wider than what can be transported on a standard vehicle. These will be passing through or in proximity to your local area, starting in the Port of Kings Lynn, Norfolk, and travelling to our Onshore Converter Station in Swardeston, Norfolk, as shown on the map below.

About the Transformer movements
A total of nine transformer movements will take place, and each unit will be transported on a 28-axle girder frame trailer, capable of carrying loads up to 350 tonnes.
The trailer will reach a maximum length of 85 metres, a width of 5.4 metres and a height of 5.2 metres. Due to these abnormal dimensions, the convoy will travel under full police es**rt and at a strictly limited speed of no more than 12mph, in accordance with National Highways Special Order legislation.
Movements are further restricted to daytime on Sundays only, which helps reduce traffic impact and maintain safe operating conditions.
Along the route, some street furniture including items such as illuminated bollards and traffic signals, will temporarily be removed to allow the load to pass safely.
These works are carried out in advance wherever possible and reinstated immediately after the convoy has passed. In a small number of cases, temporary replacements may be installed and permanent furniture restored shortly after.
The transport will be powered by two 250-tonne capacity tractor units, with a 4–5 person crew operating the trailer and managing ground safety. Their role includes monitoring tight turns and manoeuvring the equipment safely.
This operation is being delivered in close coordination with Norfolk County Council, Norfolk and Suffolk Police, and National Highways, with significant planning undertaken to limit inconvenience to residents and road users.
Dates of movements
As operations are restricted to Sundays, the nine planned movements are currently scheduled between January 2026 and July 2026.
At this stage, we can only confirm the dates of the first three movements which are:
Sunday 8th March 2026
We would like to offer you the opportunity to register to receive notifications of the remaining transformer movements when we are able to confirm these dates. To receive future notifications, please subscribe to our email distribution list at [email protected]
Please note that all our works are subject to site and weather conditions and our deliveries are dependent on agreements with Norfolk County Council and Norfolk Constabulary and are subject to change.
