Likely objections about “visual impact” would hamper any attempts to develop offshore wind farms in Northern Ireland for the time being, according to a new Stormont report.

As BBC News reports, the paper from the Department for the Economy highlights “significant issues” with regard to expected objections to wind farm projects within 13km of the shore.

As well as “visual impact”, there are also concerns relating to protected habitats around Northern Ireland’s coastline.

Northern Ireland has been exclused from the Crown Estate’s latest leasing round for such schemes. It had been hoped that the coast from Carlingford Lough to Belfast Lough would be considered for leasing.

#SeaPower - Edinburgh-based ACT Blade has designed a textile blade for wind turbines that could increase energy production by nearly 10%.

The company, an offshoot of racing yacht sail specialist AMAR Azure, designed the blade as part of the Offshore Renewable Energy (ORE) Catapult’s Innovation Challenge.

ORE Catapult then led a study that identified the company’s technology could be used to produce a textile blade up to 50% lighter and 30% stiffer than conventional fibreglass equivalents, said ACT Blade’s Sabrina Malpede.

“I didn’t have knowledge of the renewable energy sector and needed to qualify my theory with sector experts,” she added.

“From these insights we were able to create the ACT Blade, the world’s first textile blade, capable of capturing more energy than a fibreglass blade by covering a larger swept area, significantly increasing annual production.”

ACT Blade says the design has the potential to increase energy production by 9.7% and reduce the levelised cost of energy by 8.7%.

ORE Catapult research and innovation project manager Vicky Coy said: “This is just one example of how technology can be adapted from one sector to create something genuinely groundbreaking in another industry.

“There are very few innovations in any field that deliver such a dramatic performance improvement with one fell swoop. This is a tremendous opportunity not just for ACT Blade, but for the UK to establish a new textile blade supply chain for the global marketplace.”

#MARINE WARNING - As wind farm projects expand around the coasts of the UK and Ireland, the Royal Yachting Association (RYA) has raised concerns about an unexpected hazard for boaters navigating near such installations.

Taking the London Array and Kentish Flats wind farm areas in South East England as a case study, the RYA explains how rock placements, or rock berms, have been put in place to protect the power cables from these arrays at the points where they cross in shallow water.

The RYA warns that as cable crossing become more likely and more frequent, as offshore energy projects expand around the coastline, the potential for accidents is greatly increased.

"It is this cable protection that in shallow waters can reduce underwater clearance and therefore pose a risk to navigational safety," said the RYA.

Referring to the London Array and Kentish Flats specifically, the association said it "was not aware that the cables would have rock protection until we received a notice.

"It would seem that the Marine Management Organisation, Trinity House and the Maritime and Coastguard Agency were also unaware that the developers were placing a rock berm in [the[ area and are investigating how all this happened 'sight unseen' - particularly as it seemed that the original London Array Limited applications had stated that the cables would be trenched."

The Half Ton Class was created by the Offshore Racing Council for boats within the racing band not exceeding 22'-0". The ORC decided that the rule should "....permit the development of seaworthy offshore racing yachts...The Council will endeavour to protect the majority of the existing IOR fleet from rapid obsolescence caused by ....developments which produce increased performance without corresponding changes in ratings..."

When first introduced the IOR rule was perfectly adequate for rating boats in existence at that time. However yacht designers naturally examined the rule to seize upon any advantage they could find, the most noticeable of which has been a reduction in displacement and a return to fractional rigs.

After 1993, when the IOR Mk.III rule reached it termination due to lack of people building new boats, the rule was replaced by the CHS (Channel) Handicap system which in turn developed into the IRC system now used.

The IRC handicap system operates by a secret formula which tries to develop boats which are 'Cruising type' of relatively heavy boats with good internal accommodation. It tends to penalise boats with excessive stability or excessive sail area.

Competitions

The most significant events for the Half Ton Class has been the annual Half Ton Cup which was sailed under the IOR rules until 1993. More recently this has been replaced with the Half Ton Classics Cup. The venue of the event moved from continent to continent with over-representation on French or British ports. In later years the event is held biennially. Initially, it was proposed to hold events in Ireland, Britain and France by rotation. However, it was the Belgians who took the ball and ran with it. The Class is now managed from Belgium.
