The builders of Hywind Scotland, the world’s first commercial-scale floating windfarm, have reported better-than-expected leads to the primary three months of the undertaking’s operations.
A three way partnership between Norway’s Statoil and Abu Dhabi clear power firm Masdar, the 30 MW windfarm situated 25 kilometres off the Aberdeenshire coast has been powering round 20,000 households because it was launched final October.
In that point, Masdar says the undertaking has withstood one hurricane, one winter storm and waves as excessive as eight.2 metres, with manufacturing and availability above goal in every of the three months from November to January.
The typical capability issue for an offshore windfarm in winter, when the wind is at its strongest, is 45-60 per cent. Hywind Scotland, nevertheless, achieved a median of round 65 per cent: a capability issue of 100 per cent means all wind generators are producing their most output across the clock.
“These excellent outcomes illustrate the sturdiness of floating wind know-how and its potential to carry out safely and above goal within the hardest circumstances,” mentioned Bader Al Lamki, Executive Director for Clean Energy at Masdar.
“The extraordinarily encouraging efficiency of Hywind Scotland is constructive information for the event of future floating wind tasks with our companions, and helps ongoing efforts to enhance the price effectivity of floating wind.”
Hywind Scotland’s first encounter with excessive climate was Hurricane Ophelia final October, when wind speeds of 35 metres a second (m/s) had been recorded. Storm Caroline in early December was even stronger, with gusts in extra of 45 m/s (160 km/h) and waves as excessive as eight.2 metres.
Hywind Scotland’s wind generators shut down for security causes when the storms had been at their peak, however resumed operations afterwards robotically. A purpose-built pitch movement controller built-in with the turbine’s management system mitigates extreme motion.
Irene Rummelhoff, Executive Vice-President for New Energy Solutions at Statoil, mentioned: “Knowing that as much as 80 per cent of the offshore wind sources globally are in deep waters, the place conventional bottom-fixed installations should not appropriate, we see nice potential for floating offshore wind – in Asia, the west coast of North America and Europe.”
Masdar and Statoil are additionally growing the battery storage undertaking Batwind, which can retailer energy generated by Hywind Scotland.
Hywind Scotland is Masdar’s second offshore wind undertaking with Statoil, following the 402 MW Dudgeon Offshore windfarm, which was inaugurated final November. Combined with London Array, which stays the world’s largest offshore wind farm in operation, the three tasks deliver the full capability of the UK renewable power tasks wherein Masdar is an investor to greater than 1000 MW.
