Mobile assembly unit for wind turbine towers
The result is the construction of a Mobile Assembly Unit, which ensures the assembly of shell towers on site in a rational and safe way. On the basis of the development work 8 Mobile Assembly Units have been produced so far. This allows for assempbly of up to 3 full towers per week.
The purpose of this project is aimed towards the development and demonstration of a Mobile Assembly Unit [MAU], which is an important part of the Next Generation Wind Turbine Tower concept. The objective is to demonstrate that the MAU is mobile, easy to set up and take down, making it possible to move and be used at different wind turbine sites globally. The aim is to be able to raise a 100 meters tower in a maximum of 2 days. The Next Generation Wind Turbine Tower concept consists of the MAU and a new innovative wind turbine tower. The turbine tower consist of several tower elements mounted on top of each other, each tower element consists of a number of steel segments and will be bolted together on the erection site by the MAU. In spring 2011 the development of the MAU will start, which later in 2011 will result in a full-scale prototype. The successful development and demonstration of the MAU is a prerequisite for the success of the whole Next Generation Wind Turbine Tower concept
Moreover, we have developed a Stationary Assembly Unit for assembly of top section of the tower. This one unit allows for assembly of up to 3 full towers per week.
Finally, we have carried through a preliminary study project regarding robot fastening of bolts. We expect to implement the basic ideas from this project in an automated unit for fastening bolts.
Of international interest: We have constructed a Mobile Assembly Unit that makes it possible to assemble a new type of wind turbine tower on site (shell towers). The wind turbine towers can be produced in one location and can be distributed to different sites in containers. Cost for transport to site is considerably lower than for competing alternatives such as concrete towers. The shell towers are transported by standard trucks, and consequently the demands on infrastructure are lower than for traditional wind turbine tower transports.
