The Canadian developer had paused plans to install two mono-buckets in November 2019 after identifying “technical issues”. It will not finish evaluating their cause until mid-2020.

Northland has now decided against the demonstrator “due to the timing issues associated with the technical review, among other considerations”, the company stated.

This will not impact Northland’s 2020 financial guidance because contributions from the pilot project were excluded from previous estimates, it added.

In its full-year results, Northland Power had reported a non-cash impairment loss of C$98 million (US$70 million) for project costs incurred with the demonstrator project.

Deutsche Bucht’s total estimated project cost was valued at approximately €1.4 billion (US$1.5 billion).

Northland Power had installed 252MW Deutsche Bucht Deutsche Bucht (252MW) Offshorenorth-west of Borkum, Germany, Europe Click to see full details’s 31 monopile foundations by the end of September 2019.

Mono-buckets comprise steel cylindrical base and uses the foundation’s own weight and a vacuum to seal itself to the seabed.

This removes the need for piling and means the site can be returned to its natural state after the foundation has been removed.

Northland had hoped to test the foundations’ impact on marine habitats.
