The country’s largest turned steel cylinder will leave Fene


Navantia and Windar will set new milestones with their second offshore wind project, for the world’s first floating wind farm.

The first works for the Statoil contract, which involves the construction of five floating steel structures, are beginning to take place at the factory. The work is being carried out by the alliance formed by Navantia and Windar.

The installation of equipment worth six million euros, which is necessary for the manufacture of the components, has already been completed. Specifically, three pairs of 1,000-tonne capacity turning machines and one pair of 500-tonne capacity turning machines are already in the flat block workshop at the Perlío plant. This is essential machinery for handling the steel plates, which have to be turned into circular rings that are then assembled in a sort of floating capsule. The turners are used to rotate the parts, which saves a great deal of time. Windar sources pointed out that this equipment will be used to build the largest cylindrical turned structure in Spain in Fene.

Another of the innovations that the project will bring with it is the form of welding, which will be submerged arc welding. Windar has already installed two small towers for this purpose and another three medium-sized ones, to which two more telescopic towers will be added in a few days, which can be extended to facilitate welding at a height of up to 18 metres. As this type of work is carried out at two ends at the same time, it will allow four submerged arc welding operations to be carried out simultaneously, which is another innovation for the sector.

Other machines already at the Fene shipyard include a 1,000-tonne jointer, known as a crocodile, and a special roller for bending sheet metal up to 100 millimetres thick, double the thickness required for Wikinger’s order.

Windar relies on local companies to carry out most of the tasks, with work subcontracted to firms such as Acebrón, Indasa, Iris and Ártabro Samdeu. Altogether, they generate employment for around 150 employees. In percentage terms, 10% progress has already been made in this work, and it is expected that a cylinder will be ready in a fortnight’s time.

With this order, Fene will once again use its slipways, as the structures will be launched into the sea from the summer onwards.
