Plans for a huge expansion of the docks, known as Green Port Hull, were first drawn up with the idea of enticing a wind turbine or offshore company to the region.

The big gamble paid off in January when German engineering giant Siemens choose the dock as the location for a new offshore wind farm factory.

The planned works will take place around the Alexandra Dock. This will involve construction of a 600m long quay on the River Humber, reclaming 8 hectares of foreshore and dredging 62m wide and 11m deep berths.

The three-year construction programme  is expected to get underway at the end of November in time for opening in July 2014.

Associated British Ports is breaking the big job down into three distinct work packages.

The first, estimated to be worth up to £60m covers the main marine works, another £10m package involves infilling part of the Alexandria Dock, while the final contract, worth around £15m, will cover construction of port pavements including site drainage, services, area lighting and fencing.

Interested contractors have until 31 May to submit PQQs. Further information is available by calling Sean Blissett on 01472 348224 or emailing [email protected]
