ALE All Done on Hornsea One

ALE has completed its full scope of work on Ørsted’s Hornsea Project One offshore wind farm.

The project concluded in February 2019 when ALE completed the final discharge of the 106th transition pieces (TPs) onto the installation vessel.

ALE was contracted by GeoSea to provide the specialist offshore engineering alongside the marine transportation, sea-fastening, load-out and ballasting of the TPs in the UK.

ALE’s scope on the project began with the load-out of the TPs, each weighing 337t and measuring 25m high, from the fabrication yard onto the SARAH S barge.

Conbit provided the engineering for storage and SPMT stability during the ALE transport operations at the yard. For the structural engineering, the Conbit team performed the structural integrity and sea fastening calculations of the grillages on the barge deck of the barge. Once on the barge, the TPs were transported on the River Tees to the discharge berth.

The project was the inaugural job for ALE’s SARAH S barge.

“This has been a long-term project and ALE provided the full, specialist marine scope of work for these operations, which, combined with the strength of the ALE – Conbit collaboration, has demonstrated the breadth of ALE’s expertise,” said Steve Small, ALE’s Commercial Manager – Marine.
