Heavy lift specialist ALE has completed works for Orsted’s Hornsea 1 wind farm off the east coast of England.
ALE was contracted by GeoSea to provide the specialist offshore engineering alongside the marine transportation, sea-fastening, load-out and ballasting of 106 transition pieces (TPs) for the 1.2GW offshore wind project.
The company’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 barge.
Conbit provided the engineering for cost-effective storage and self-propelled modular transporters 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 SARAH S barge, the inaugural job for ALE’s vessel.
Once on the barge, the TPs were transported on the River Tees to the discharge berth.
“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 ALE marine commercial manager Steve Small.
