Multi-service operations and handling of offshore wind components, UK

Overview

ALE has successfully executed the onshore heavy lifting, transportation and pre-assembly for offshore wind operations in Hull, UK, as part of a four-year Crane Framework Agreement. So far, all components have been loaded-out onto the vessel and received by ALE.

 

Services Required

ALE has been executing the handling and pre-assembly of offshore wind components, comprising of imported towers, nacelles and blades to be used on the Dudgeon and Race Bank offshore wind farms.

ALE has been providing a multi-service operation, involving the load-in and load-out, transportation and general handling of hundreds of offshore wind components.

With some rotor blades as long as 75m and nacelles as heavy as 360t, ALE are adopting a Ro-Ro process (where possible) instead of lifting, to provide a safer and more cost effective method.

ALE is utilising a range of equipment to carry out this complex scope of work, including SPMTs and specialist cranes: the LR1750/2 with 750t capacity, the LR1300 with 300t capacity and a telescopic crawler crane with 120t capacity.

So far ALE has performed over 4,000 transport operations and executed over 3,300 lifts, with a combined handling weight of 58,3740t, for the multiple offshore wind farm contracts.

The wind farm project sites include Green Port Hull, pre-assembly base for both the Dudgeon offshore wind farm 32km north of Cromer, Norfolk, which will generate 402MW of clean power, and the Race Bank offshore farm 27km north of Blakeney Point, Norfolk, generating 580 MW. The other project site is the pre-assembly base for the Galloper offshore wind farm 30km off the Suffolk coast, which will generate 336MW, in Great Yarmouth.  These three projects will power over 1.2 million UK homes in total.
