Offshore construction is expected to kick off next month for the Neart na Gaoithe  (NnG) offshore wind farm.

Located at least 15.5 km off the Fife coast, Scotland, the
Neart na Gaoithe site is approximately 105 km2 with water depths ranging from 40 to 60 m below LAT. Pile installation will be the first licensed construction activity to commence within the Wind Farm Area.

The
Saipem 7000 will mobilise from Mekjarvik, Norway and will commence pile installation for Neart na Gaoithe from the 9th August 2020, with work scheduled to conclude in Q3 2021.

Saipem was awarded a contract for the engineering, procurement, construction and installation (EPCI) for the 54 turbine foundations and two offshore substation foundations as well as the transportation and installation of the relevant topsides. Scottish engineering firm BiFab has been subcontracted to build eight of the foundation jackets. Each jacket foundation will have three pin piles and is expected to stand over 80 m high.

The
Saipem 7000  semi-submersible crane vessel has the capacity for heavy lift operations up to 14,000 tonnes  in water depths greater than 2,000 metres. The vessel has an overall length of 197.95 m and is equipped with two twin Saipem 7000 model fully revolving bow mounted Amhoist cranes as well as pile driving hammers.

The 450 MW project will feature 54 Siemens Gamesa SG 8.0-167 DD turbines. Fred Olsen Windcarrier's
Blue Tern will install the turbines in 2022 with the Port of Dundee as the loading harbour for the wind turbines.

The £2bn
Neart na Gaoithe offshore wind farm is owned by EDF Renewables and ESB. It was awarded a CfD by LCCC in February 2015, with a strike price of £114.39/MWh. The first commercial supply of electricity is expected by 2023. Once fully operational, it is expected to generate electricity for around 375,000 homes.
