GRAHAM's Solution

This award winning project, handed over on budget and ahead of programme in January 2017, has laid the foundations for the Port of Hull’s future position as a world-class centre for renewable energy.

Pivotal to its success was a robust collaborative approach established with the array of skilled subcontractors who combined to deliver 60% of the entire workflow.

Complex works, achieved through 1.5 million RIDDOR free ‘man-hours’, included infilling one third of Alexandra Dock with 780,000m3 of material while reclaiming 7.5 hectares of the Humber River to create a new 650m quay wall. Construction also incorporated the dredging of a new pocket berth, the completion of earthworks and surfacing and the building of internal access roads and service networks.

The composition of a new roll on/roll off ramp, the demolition of existing buildings and the reengineering of Ro-Ro deck design, providing a 5-week improvement on the original programmed duration, encompass core elements of this innovative project.

"The investment will benefit the UK economy by creating green jobs and growth as well as providing secure, sustainable and low-carbon energy. The development will also help to drive down the costs of offshore wind. It marks the beginning of a new industry based here and exporting worldwide"

Ed Davey Secretary of State for Energy and Climate Change

"It’s fantastic to see vessels using the new facilities and testing out our construction. We’re delighted to see this investment become operational, giving life to a project that is already creating jobs and that will make a significant contribution to the regional and national economy"

Simon Brett ABP Head of Projects Humber
