Wind Turbine Park Construction

Havoygavlen Wind Park - Masoy, Norway

 16 Nordex N80 2.5 MW wind turbines

Nordex Turnkey Project

 Construction began in April 2002 with completion expected in October 2002

With an average wind speed of more than 9 m/s, the wind park has a capacity of 40 megawatts and will generate up to 120 GWh of electricity per year. Havoygavlen is the world's northernmost wind park (71^o N latitude), located roughly 100 kilometres south of the North Cape, Norway.

Damage to wind turbine at Havöygavlen in Norway

Hamburg, November 4, 2002. On Tuesday afternoon (October 29), one of the Nordex wind turbines installed in Norway was damaged. At around 5:00 pm in the afternoon, the nacelle including the rotor was severed from the tower. Prior to this, the rotor had been turning at an excessively high speed as a result of an incorrect manual adjustment to the turbine control system. The turbine had only recently been put into operation. The detailed control log reveals that at the time of the accident the turbine was operating at 44 rpm (tipspeed 663 km/h). Under normal operating conditions, a maximum of only 19 rpm (tipspeed 289 km/h) is permitted. This high turbine speed exerted extreme strain on the turbine, ultimately causing the incident. According to Nordex, the wind speed at the time of the accident was up to 15 m/s, normally an uncritical speed for this turbine. On the basis of investigations made so far, the accident was caused by incorrect intervention in the controlling system. The turbine had signaled that the rechargeable batteries supplying the rotor brake (pitch drives) in the event of a power failure were not sufficiently charged. In order to start the turbine, an automatic safety-system, which would normally have prevented operation of the turbine with this defect, was deactivated. During the following operation, there was a failure in the normal power supply, with the result that the turbine turned at an uncontrolled speed. Further investigations have been initiated to determine how an unauthorized deactivation of critical functions of the safety system could occur. Nordex stresses that this incident was a one-off occurrence which has nothing to do with the turbine technology used. No-one was hurt and nor was there any further damage to property as a result of the accident.
