Ørsted says offshore UK windfarms need urgent repairs

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.

Ørsted points to possible reason for EUR 403 million cable problem

Leading offshore wind developer Ørsted has suggested that a scour protection method which left the inter-array cables unstabilised could be the potential reason for an up to DKK 3 billion (EUR 403 million) issue across up to ten wind farms in Europe. As reported earlier, Ørsted first became aware of the problem earlier this year during an inspection after an outage at the Race Bank wind farm offshore the UK.

Cable failures hit offshore wind farms

The company identified a total of 10 projects in the U.K. and Europe that used the same design that may need to be remedied. Some projects will be easy to fix. The company can just dump more rocks on top of the cables to make them stay in place. ...But in other cases, Orsted will have to repair or replace the cables. That’s the pricey option that will make up the bulk of the cost, Wiinholt said.

Damaged offshore wind cables to cost Orsted almost half a billion dollars: CFO

“To a large extent we will be able to mitigate it through stabilising the cable protection system. It will be done by dumping rocks on top of the rocks that are already there.” At other wind farms, the cables are so damaged that the company will either need to repair or replace them, which is more expensive than dumping more rocks on top of the existing protection layer.

‘Wind farm push could face barrier’

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.

Ocean life is at risk from turbines: Ramping up wind power off British coast will cause loss of marine life by 'urbanising the sea', experts warn

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.’

Offshore wind plans will drive up electricity prices and require ‘massive industrialization of the oceans’

“Environmentalists have not yet grasped the massive industrialization of the oceans now underway and proposed.” ...If the advisors on Biden’s climate team are serious about protecting the environment, now would be a good time for them to reconsider the massive industrialization of the oceans that is now underway. It might even make them think about preventing America’s existing fleet of nuclear reactors from being prematurely shuttered.

Offshore wind farms: Study to be carried out on risk of seabird collision with turbines

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.

Protect marine life from WWII bomb detonations on wind farm sites, urges Joanna Lumley

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.

Floating offshore wind sector faces ‘huge’ mobilisation challenges

“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.

Zion Lights, former Extinction Rebellion spokesperson, has doubts about Boris Johnson's plan to make every home wind-powered by 2030

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.

Boris Johnson’s plan to expand wind power welcomed, but 'funding doesn't match rhetoric'

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.

Anger as Fife’s BiFab overlooked for work on neighbouring wind farm in favour of Chinese company

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.

Thanet extension DCO application rejected

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.

Merkel cabinet shocks sector with proposal for negative bidding at offshore wind auctions

The amendment approved today also stipulates that in the case of zero bids, one or more subsequent auctioning rounds would take place at future German offshore wind tenders. This so-called ‘dynamic bidding procedure’ would determine zero-subsidy bidders’ so-called ‘ability to pay’ in order to find out how much a future operator must pay in grid fees to transmission system operators (TSOs). Successful bidders will also need to pay the government for preliminary investigations of potential offshore wind sites.

Government blocks plans for extension to Vattenfall's Thanet offshore wind farm

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.
