Ecosse, contracted by Siem Offshore Contractors, has mobilized its SCAR ploughing technology by road from Aberdeen to Gdansk, Poland and cleared several thousand boulders including some over13ft tall from the cable routes, making 260 individual passes in varying soil conditions.
Ecosse managing director Mike Wilson said that the company created a lot of firsts on EnBW Baltic 2 and it was its largest contract to date.
The Baltic 2 wind farm includes 80 wind turbines, which were installed in the German exclusive economic zone of the Baltic Sea.
"It couldn’t have gone better and our client is now convinced that our zero-risk pre-trenching option, where the hard work is done before the cable is present, is the future for cable installation," Wilson added.
"We are hopeful that following the success of EnBW Baltic 2 we will secure a frame agreement for boulder-clearing and pre-lay trenching services for Siem Offshore Contractors, who are tendering on a range of renewables schemes."
