A breakthrough
international investment

It was the first wind farm erected on the North Sea. Horns Rev 1 is located almost 14 kilometres off the Danish coast line and consists of 80 wind turbines situated at the depth of 6 to 14 meters. The turbines generate 160 MW of electricity.

This satisfies the demand of 150,000 Danish households, i.e. almost 2% of the total annual electricity consumption in whole Denmark.

Managing a crew
of specialists

Completion of Horns Rev 1 project involved managing staffing of functional positions on jack up oil platform in line with the requirements of the International Maritime Organization for the biggest offshore wind farm on the North Sea.
