Straddle Carrier Case Study
Carrying wind power forward
Collaboration by two companies known for innovation in their own particular business sectors has facilitated the production and transportation of a revolutionary new design of wind turbine tower. Irish materials handling provider Combilift and Danish manufacturer Andresen Towers pooled expertise to address the logistical challenges involved in manufacturing and moving extreme lengths of product which form the basis of Andresen’s new tower construction.
A
ndresen Towers, established in 2011, is part of the IAI Group and has more than 25 years’ experience in the production
of bended and bolted steel towers. The com- pany has recently taken its original concept a stage further with the design of its patented shell towers and has secured an exclusive long-term contract with Siemens Wind Power, who will sell its products. New production and warehouse facilities have been set up at Andresen’s HQ in Nyborg and nearby Langeskov which cover an area of 25,000 sq m.
“In order to make wind energy a more competitive alternative to fossil energy sources, we have harnessed our technology to build the next generation of much higher towers,” says CEO Tom Andresen. “These can exploit the better wind conditions to generate a larger output which in turn re- duces costs. For example, an increase in the hub-height from 80m to 125m will decrease the price per KWh by 25%.” The increased
height of the steel shell towers compared to those currently available is due to the larger diameter and the reduced material thickness allows them to be produced from steel coils. These are cheaper than traditional steel plates and result in lighter towers. No weld- ing of the structure is required as it is held to- gether by tension controlled bolts, which do not need any retightening after installation.
