DONG Energy has contracted SPT Offshore for the structural and geotechnical design of suction bucket foundations for potentially five transformer substations, namely Burbo Bank Extension, Race Bank and Walney Extension.
The 4 suction buckets will potentially form the foundation of 4-leg jackets supporting high-voltage transmission substations weighing approx. 2500 ton each. The water depths vary from 11 to 29m LAT. Installation of the first substation jacket is planned for 2016.
