COORDINADORA and OCTRA successfully performed the transport of a testing offshore wind turbine. The wind generator itself was one of the newest and heaviest models available in the market, with a power production of 6 MW. The turbine is composed by three tower sections of 30 m long each one, a 420 Mt nacelle and a set of three blades with a unitary length of 74 m.
The tower sections were shipped from Avilés port (Spain), where manufacturing facilities are located, sailing afterwards to an intermediate port, Montoir (France), where the Nacelle was added to the shipment. The performing Heavy Lift Vessel sailed out to Denmark, with final destination Hanstholm, the closest port facilities to Osterild where it is stablished the onshore testing plant.
The operation involved both marine & land transport movements up to final destination. Furthermore, it had the additional complexity of having to transport the bottom tower section (230 Mt, CoG at 12 m height) in upright position. This was a client´s requirement, so the transformers and auxiliary equipment had to be assembled in advance, avoiding spending time and resources on site.
