 This weekend we go again. A rotor blade came loose from a Vestas turbine and thrown away by air. Now I want the industry set up a haverikommision. The latest incident occurred on Forge Holmen outside Falkenberg on Sunday morning. One rotor blade was torn loose from a small wind turbine of the type Vestas V27 and fell to the ground near a hiking trail. No one was injured. - But now we have to do a proper investigation and see what caused this, "says Jan-Åke Jacobsson, Chairman of the Swedish wind energy association (SVIF) to New Technology on Monday. Accident Investigation underway Right now, he discusses and representatives from the Danish manufacturer Vestas to put together an Accident Investigation Board. According to preliminary plans, such a group composed of two persons from Vestas, two representatives from industry associations Swedish Wind Energy Association and the Swedish Wind Energy and a member of the Energy Agency. - It is important for the industry that we take these accidents seriously and find out why they happen, "says Jan-Ake Jacobsson to new technologies. These accidents are more and more In recent years the wind industry has grown rapidly. But as more and more new items placed, and the old aged accidents have also increased. The Danish wind power authority Godkendelsesekretariatet for wind turbines, there have been 27 accidents in Denmark since 2000. In 12 cases, the entire rotor blade had broken off and used in 12 cases, parts of the rotor blade had fallen. Last year, Vestas was hit by two spectacular accidents in the Nordic countries. 1st in January dropped a 850-kilowatt works on Gotland's one rotor blade. Investigation of the accident showed that the bolts / screws have not been sufficiently tightened. 2nd A month later came off a sheet in a 650-kilowatt works in Danish Odsherred in Jutland. It flew 60 meters before it landed.  At Forge Holmen are five wind turbines - three private and two owned by Falkenberg Energi. It crashed wind turbine is a Vestas V27 225 kW Verification of all screws After the accidents showed Vestas internal investigative procedures failed to Vestas in the servicing and maintenance. Therefore, the company sent out its service technicians to check the screws on older turbines. Since priority was given control of the Vestas V39-v47, V52 and Nordtank 300-600, part of Vestas' product portfolio. What caused the weekend accident is still unclear. Timar Gustavsson, which owns the wind turbine, said Vestas regularly checked it and that the disruption was minimal in the present work since it became operational in June 1992. - It seems that the whole wing is torn from its mounts, "he told New Technology. Closed until further notice The area has four wind turbines of the type Vestas V27, with an output of 225 kW. They are suspended until further notice. V27 is an old proven model, which sold in large volumes worldwide. Rotor diameter is 27 meters, the tower height 31 meters. New technologies have searched Vestas for a comment but were unable to someone who wishes to speak. |
