SPT Offshore to Provide Suction Foundations for DONG Energy

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 29 meters LAT. Installation of the first substation jacket is planned for 2016.

SPT Offshore is an independent offshore contractor specialised in suction pile foundations and Self Installing Platforms for the development of marginal and medium sized oil and gas fields. For the development of offshore wind farms, SPT has developed a one piece self installing wind turbine concept, which allows transport and installation of a wind turbine foundation complete with pre-assembled wind turbine. The SIWT concept offers flexibility in scheduling and a low-cost and noise-free installation.

Furthermore, SPT Offshore provides suction piles, Suction Pile Clusters and Suction Embedded Anchors for the mooring of floating units (FPSOs, MOPUs, buoys, FSUs, etc), subsea structures and subsea pipelines.
