Walney 1 & 2
In the first phase, 51 offshore wind turbines will be installed and when the entire wind farm is finished, there will be 102 turbines, making the Walney Wind Farm one of the largest in the world.
ISC has prepared the technical details in the tender material, detailed design and supervision of the offshore transformer platform’s topside and jacket.
The transformer platforms are closed units with two transformers located centrally in a partially open area. All the electrical installations, workshops and other installations are located inside.
The four-legged jackets rise 43 and 45 m above the seabed and are traditional x-shaped grid braced constructions. The piles are connected to the jacket via pipe sleeves and are driven 50 m into the seabed. The top 3 m is soft mud and has necessitated laying 3-4 m high mud mats on the seabed during the installation phase. The top side alone weighs 1250 tonnes.
ISC carries out all disciplines such as layout, offers, tender documentation and detailed design including electrical, HVAC and security installations. We have also designed sea transport and lifting fittings for both jackets and topsides, as well as certification documents for DNV verification.
The first wind turbine foundation was installed in April 2010. Walney 1 was installed in mid-2012 and the entire wind farm was commissioned on February 9, 2012
