East Anglian companies have won £9m of contracts to service wind farms off the Suffolk and German coasts.

ScottishPower Renewables has chosen Great Yarmouth-based offshore firms Seajacks and Gardline to take on roles on its East Anglia One and Wikinger projects.

The news comes just days after Innogy, which is leading the Galloper wind farm project in waters off Suffolk, awarded multi-million pound construction contracts to Jackson Civil Engineering and RG Carter.

Seajacks' Kraken vessel is currently working on the offshore substation in the Baltic Sea for the Wikinger wind farm as part of a contract in the region of £3m. The deal comes off the back of the marine engineering firm's work on the East Anglia One scheme.

Survey contractor Gardline, a member of the EDP/EADT Top100, has been awarded contracts worth more than £6m for pre-construction surveys across the East Anglia One site, off the coast at Lowestoft. Gardline's subsidiary Alpine will also carry out a geophysical survey in Massachusetts, in the United States, for the Vineyard Wind Project, which is half owned by ScottishPower Renewables' Avangrid Renewables.

Jonathan Cole, managing director of offshore wind at ScottishPower Renewables, said: 'Seajacks and Gardline are at the forefront of their respective fields, and we look forward to a successful partnership with both companies as they deliver important projects for our global offshore wind power developments.'

He said that firms in the area's supply chain offered 'industry-leading levels of expertise', adding: 'Companies based in the East Anglia region have the potential to export their services anywhere in the world where offshore wind schemes are being considered.'

When complete, the £2.5bn East Anglia One wind farm should produce enough energy to power the equivalent of 500,000 homes.

Seajacks chief executive Blair Ainslie said he was 'delighted' at securing the contracts.

'We will be installing jacket foundations on East Anglia One with Seajacks' Scylla and supporting the commissioning of the Wikinger offshore substation,' he said. 'This shows the full range of services we are able to provide from our Great Yarmouth headquarters.'
