#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."

Ferry & Car Ferry News The ferry industry on the Irish Sea, is just like any other sector of the shipping industry, in that it is made up of a myriad of ship operators, owners, managers, charterers all contributing to providing a network of routes carried out by a variety of ships designed for different albeit similar purposes.

All this ferry activity involves conventional ferry tonnage, 'ro-pax', where the vessel's primary design is to carry more freight capacity rather than passengers. This is in some cases though, is in complete variance to the fast ferry craft where they carry many more passengers and charging a premium.

In reporting the ferry scene, we examine the constantly changing trends of this sector, as rival ferry operators are competing in an intensive environment, battling out for market share following the fallout of the economic crisis. All this has consequences some immediately felt, while at times, the effects can be drawn out over time, leading to the expense of others, through reduced competition or takeover or even face complete removal from the marketplace, as witnessed in recent years.

Arising from these challenging times, there are of course winners and losers, as exemplified in the trend to run high-speed ferry craft only during the peak-season summer months and on shorter distance routes. In addition, where fastcraft had once dominated the ferry scene, during the heady days from the mid-90's onwards, they have been replaced by recent newcomers in the form of the 'fast ferry' and with increased levels of luxury, yet seeming to form as a cost-effective alternative.

Irish Sea Ferry Routes

Irrespective of the type of vessel deployed on Irish Sea routes (between 2-9 hours), it is the ferry companies that keep the wheels of industry moving as freight vehicles literally (roll-on and roll-off) ships coupled with motoring tourists and the humble 'foot' passenger transported 363 days a year.

As such the exclusive freight-only operators provide important trading routes between Ireland and the UK, where the freight haulage customer is 'king' to generating year-round revenue to the ferry operator. However, custom built tonnage entering service in recent years has exceeded the level of capacity of the Irish Sea in certain quarters of the freight market.

A prime example of the necessity for trade in which we consumers often expect daily, though arguably question how it reached our shores, is the delivery of just in time perishable products to fill our supermarket shelves.

A visual manifestation of this is the arrival every morning and evening into our main ports, where a combination of ferries, ro-pax vessels and fast-craft all descend at the same time. In essence this a marine version to our road-based rush hour traffic going in and out along the commuter belts.

Across the Celtic Sea, the ferry scene coverage is also about those overnight direct ferry routes from Ireland connecting the north-western French ports in Brittany and Normandy.

Due to the seasonality of these routes to Europe, the ferry scene may be in the majority running between February to November, however by no means does this lessen operator competition.

Noting there have been plans over the years to run a direct Irish –Iberian ferry service, which would open up existing and develop new freight markets. Should a direct service open, it would bring new opportunities also for holidaymakers, where Spain is the most visited country in the EU visited by Irish holidaymakers ... heading for the sun!
