Neart Na Gaoithe
Transformer chosen: Mainstream Renewable Renewable's 450MW Neart Na Gaoithe project in Scotland will feature Siemens' Offshore Transmission Module (OTM). The new technology removes the need for a large, heavy offshore substation and the associated specialised installation vessels. Instead, two turbines can support the OTM modules, which include transmission equipment.
Mainstream also said vessels contractor GeoSea will use a "Boom Lock" system developed by High Wind BV. It allows installation of offshore wind components in winds up to 15 m/s, reducing the workdays lost to unsuitable weather. The system is mounted on an offshore crane and controls the movement of the load and the crane hook.
Both systems were unveiled in March. Mainstream said the use of the two could help the project "produce the cheapest ever electricity generated from a UK offshore wind farm". 13-Apr-15
Construction start announced: The Kentish Flats Extension is set to begin construction in May. The foundations and turbines will be installed by GeoSea's Neptune vessel.
Installation of Vattenfall's 49.5MW project off England's south east coast should be completed by the end of August.
Vattenfall posted a Notice to Mariners detailing the vessel's work. Unexploded ordnance surveys at the project began in March. 14-Apr-15
Grouting contract: FoundOcean will has been contracted by Van Oord to grout the foundations at Northland Power's 600MW Gemini project in the Netherlands.
For the first time, the company will use its MasterFlow 9800 grout on 150 foundations at the site, located off the Dutch coast.
Van Oord is the project's engineering, procurement and construction contractor, and holds a 10% stake in it.
In January, cabling specialist VBMS was chosen to carry out dredging and cabling work at the development. 14-Apr-15
