#MostPowerful - The world’s most powerful wind turbine blades continue to ‘breeze’ into Belfast Harbour, as part of a project to develop the Burbo 2 offshore wind farm on the Irish Sea as previously reported on Afloat. The blades – plus their 88m high towers are visible from across much of the city.

The first six massive 80m long blades – the equivalent length of nine double decker London buses – have arrived in Belfast Harbour’s offshore wind terminal from the Isle of Wight. The completed wind farm will provide enough renewable electricity for 230,000 homes.

Each blade weighs 35 tonnes and the turbines, which will be assembled in Belfast Harbour, will ‘sweep’ an area larger than the London Eye (21,124 sq m). During this phase of the project, 32 turbines will be assembled in Belfast. The blades are manufactured in the UK by MHI Vestas Offshore Wind.

After the turbines are assembled in Belfast they will be transported on a state-of-the-art jack up vessel which will install them on the seabed, just off the coast of Liverpool. The wind farm will cover 40km2, the same area of almost 6,000 Premiership football pitches.

Once operational, the tip height of the blade and turbine will be almost 200m. The record level of energy produced from just one turbine in a 24-hr period is 192 MWh – the same amount of energy produced by 22,600 litres of oil.

The blades, which were designed, tested and manufactured at the MHI Vestas on the Isle of Wight, will be the first UK built blades to be installed at a British offshore wind power plant.

Waszp sailing

The Waszp project was conceived in 2010 by Andrew McDougall, designer of the world-beating Mach 2 foiling Moth. 

The Waszp was created as a strict one-design foiler, where, as the class says “the true test when raced is between crews and not boats and equipment”.

The objective of the class rules is to ensure that this concept is maintained. Keeping possible modifications to a minimum ensures fair racing across the fleet, helps to reduce the overall cost to the sailor and reduces the amount of time in the workshop. 

The popularity of the WASZP has proven that the boat and the concept work. In October 2021, 1237 boats had been sold to over 45 countries. 

The top speed recorded on the foiling dinghy is 26.7 knots. 

60-95kgs+ is a weight range competitive across varied conditions with rigs knowns as ‘8.2’ and ‘6.9’.

The cost of a Moth dinghy in Europe is €14,400 inc VAT + shipping according to the manufacturers in October 2021.
