The dredging project which will allow deeper-drafted ships to call at ports along the Humber Estuary has provided the foundations for the Siemens offshore wind turbine manufacturing, assembly, installation and service facility at Associated British Ports’ (ABP) Alexandra Dock in Hull.
On Oct 15, ABP said: “Dry land has now breached the water’s surface in the dock for the first time since it was completed 130 years ago, after the dredger Eke Mobius pumped 1mn cu m of material from the estuary into the dock to infill one third of the water area.” The trailing suction dredger, of 6,725gt, is owned by Strabag Wasserbau, of Hamburg.
ABP’s project team and engineers working for main contractor the Graham Lagan Construction Group Joint Venture have also stored sand for use during the seven-hectare reclaim for the new quay. The reclaimed area will be used to store wind turbine components prior to loading onto installation vessels and as well as providing material for the infill activity, the dredged area will improve navigation for the wider estuary.
Next spring, the dredging of the new berths will begin, which will allow deeper drafted wind installation vessels to go alongside the newly-built quay wall.
