Displaying items by tag: Most powerful wind blades

#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.

Shipyards

Afloat will be focusing on news and developments of shipyards with newbuilds taking shape on either slipways and building halls.

The common practice of shipbuilding using modular construction, requires several yards make specific block sections that are towed to a single designated yard and joined together to complete the ship before been launched or floated out.

In addition, outfitting quays is where internal work on electrical and passenger facilities is installed (or upgraded if the ship is already in service). This work may involve newbuilds towed to another specialist yard, before the newbuild is completed as a new ship or of the same class, designed from the shipyard 'in-house' or from a naval architect consultancy. Shipyards also carry out repair and maintenance, overhaul, refit, survey, and conversion, for example, the addition or removal of cabins within a superstructure. All this requires ships to enter graving /dry-docks or floating drydocks, to enable access to the entire vessel out of the water.

Asides from shipbuilding, marine engineering projects such as offshore installations take place and others have diversified in the construction of offshore renewable projects, from wind-turbines and related tower structures. When ships are decommissioned and need to be disposed of, some yards have recycling facilities to segregate materials, though other vessels are run ashore, i.e. 'beached' and broken up there on site. The scrapped metal can be sold and made into other items.
