IBERDROLA, through its UK subsidiary ScottishPower Renewables, has commenced work on its 400MW Wikinger offshore wind farm in the Baltic Sea.

British company Gardline Group and GEO of Denmark have secured two contracts at a combined value of $18m to conduct a geological survey of the area to help the company determine the foundations required for the German project.

IBERDROLA global offshore division & ScottishPower Renewables CEO Keith Anderson termed the sub-surface drilling operations to conduct the geological survey a crucial part of the largest deep-water offshore wind farms in the world.

"The outcome of geotechnical testing will provide us with valuable data on the morphology of the seabed, which will directly affect the construction and design of the columns supporting the giant wind turbines," added Anderson.

The project has a capital outlay of €1.6bn and entails installation of 80 turbines of 5MW each and 150m tall, standing 30kms off the coast of Rugen Island in the Baltic Sea.

The project is capable of generating enough energy to supply 350,000 German households each year.
