The Danish wind power firm Ørsted has warned that up to 10 of its giant offshore windfarms around the UK and Europe will need urgent repairs because their subsea cables have been eroded by rocks on the seabed. ...Ørsted has found that the rocks placed at the base of the wind turbine foundations to prevent the erosion of the seabed were responsible for wearing down the cable protection system which, in a worst case scenario, could cause the cables to fail.
EDF Renewables development manager Dave Sweenie, who has been working on the Neart na Gaoithe (NnG) wind farm for more than a decade, said if projects begin to ramp up at the same time, limited infrastructure could cause bottlenecks to occur. When other industries are thrown into the mix, ports will begin to fill up “very quickly”, creating a “real barrier” for offshore wind deployment, Mr Sweenie warned.
Melanie Austen, Professor of Ocean and Society at Plymouth University, said: ‘We’re talking about effectively urbanising the sea by introducing these structures. Introducing hard structure through cables and the turbines themselves is going to change the ecology and the ecosystem.’
RSPB Scotland has welcomed the new research, with the charity hopeful it will accurately expose the dangers of offshore windfarms to wildlife for the first time. North anti-windfarm protesters, however, claim the commissioning of the study is “too little, too late”. The 11-turbine Aberdeen Bay Wind Farm is already operating, while two of the largest offshore wind projects in the world ...are under construction.
Ms Lumley and marine conservation groups fear that more whales and dolphins could be harmed after Boris Johnson promised to ramp up the UK’s offshore wind capacity and are calling for less harmful methods to be used. There is limited data on the impact of exploding ordnance in the sea, but a 2015 study on one area of the North Sea suggested 88 explosions had “very likely” caused permanent hearing loss in 1,280 Harbour Porpoises.
“Not only are there huge engineering and technical challenges but there’s just a huge mobilisation challenge for the industry to get up and running. “One of the biggest obstacles that we all face at the moment is establishing that framework of different policies to enable that rapid growth, because it has to be swift.” Mr Torr explained another challenge lies in driving down the cost of developments in order to make them more competitive.
For all the invocations of harnessing our gusty shores in some ‘green revolution’, the proclamations do not stand up to scrutiny. Even if we cranked up wind power provision to the level the Prime Minister proposes (40 gigawatts), this amount would power only about half the homes in Britain - or 7 percent of the total national energy demand.
But he warned: “It won’t be straightforward. The key challenge is to bring down the cost of future floating farms which are a very long distance from the coast – that’s where most of the untapped wind resource is and that is the one technology which is not yet mature enough, so that would need to be accelerated to meet this challenge.
A trade union has called for a halt to new offshore wind farms until a local supply chain is established. GMB London echoed the growing anger from GMB Scotland after it was announced last week that contracts to supply turbine jackets for SSE’s offshore wind farm, Seagreen, in Angus, were awarded to firms in China and UAE.
All of the turbine jackets for Scotland’s largest offshore wind farm will be fabricated thousands of miles from the North Sea despite a Government-supported bid by Fife’s BiFab. The firm has failed to win any work on the multi-billion pound Seagreen offshore wind farm project, located just a few miles from its yards in Burntisland and Methil.
The concerns include the effect of the project on navigational safety of shipping traffic in immediately adjacent waters, the resilience of facilities and services accessed by that traffic, and in this context, the degree to which the proposed development was policy compliant.
The government has refused planning permission to a 340MW extension to Vattenfall's Thanet wind farm off the southeast coast of England, dealing a blow to the company's plans to expand the site's renewable power capacity. Business Secretary Alok Sharma refused consent to the project yesterday, citing concerns about the proposed extension's impact on marine navigation, shipping, and ports in the area.
A three-day online public inquiry will take place over the planned compulsory purchase (CPO) of land, including part of Carnoustie’s famous golf links, for work associated with what will become Scotland’s largest offshore wind farm.
A billion-pound wind farm has been closed for more than two weeks after a technical fault brought it to a standstill. Rampion Wind Farm, which is 13km off the Sussex coast, is still out of commission after an electrical problem on October 26.
The energy minister is to launch a review into the impact wind farms have onshore amid claims the countryside is being “concreted over” with substations and cable corridors built as supporting infrastructure. The move has been welcomed by campaigners who have been fighting proposals in the East of England to build substations and cable trenches “the size of Wembley stadium” to get electricity from wind farms to the National Grid.
A decision on whether the world's largest offshore wind farm will be built has been delayed amid fears it will harm endangered birds. The Government was meant to rule on October 2 whether or not the Hornsea Three wind farm - 120 kilometres off the north Norfolk coast - would get the go-ahead.
"We'll be absolutely there on the front line to attack it, because we believe what we've got now is more than we should have to bear... We've got the Snowdonia National Park and looking out from that you'll see this forest of metal turbines. It's just diabolical," he said. "Scenery is all part of what we sell as a tourist destination and tourism is our only industry. To put those there is industrialising the seascape.
RSPB Scotland director Stuart Housden stressed that the wind farm projects threatened to kill thousands of Scotland’ s internationally protected sea birds every year, including thousands of puffins, gannets and kittiwakes. “While we fully support deployment of renewable energy, this must not be at any cost,” he said.
Data collected will include three-dimensional radar tracks as well as video footage of birds moving through the development. It will allow identification of specific species, showing flight height as well as individual and group behaviour. The findings will reveal whether and how often birds might be colliding with the giant structures or if they are being displaced from important feeding grounds.
The blackout may have been caused by the unexpected shutdowns of the Hornsea offshore wind farm, which is owned by the Danish wind farm company Orsted, and the Little Barford gas-fired power plant, owned by German utility giant RWE. National Grid data showed both of the generators dropped from the grid at around the same time. ...“We would have expected the system to cope with this size of loss of generation,” an Enappsys spokesman said. “This implies that there may have been [other] issues at the time of the trips.”
