Southbay Civil Engineering Limited construct new quay wall which will be used to service the world’s largest off shore windfarm.

Thursday, 26th May 2022

Southbay Civil Engineering Limited have successfully completed the construction of a new quay wall within the Tyne Dock Enterprise Park, which forms part of the Port of Tyne. This new structure will enable the mooring of Service Operation Vessels, which will be used to support the operation of Dogger Bank Windfarm, which once complete will be the largest offshore windfarm in the world. The project, which was completed with no reportable incidents, involved constructing this new structure within a challenging environment due to unknown ground conditions, with this former industrial site used for shipbuilding and offshore module fabrication.

This design and build contract involved the construction of a 113m combi wall, consisting of 24no. 1067mm diameter and 15no. 1422mm diameter tubular piles. Due to high levels of bed rock, pile top drilling was required when installing these piles to ensure the required depth was achieved. The quay wall is connected to the land via a series of heavy tie bars and anchor piles. Associated groundworks included the construction of an 18m wide concrete ground slab stretching the length of the quay, with a bearing capacity of 10t/m2. The new quay also includes fendering, bollards, grab chains, safety ladders, and required services.

In delivering the project a number of social value initiatives were embraced, including holding an open day to civil engineering students from Northumbria University, which provided the opportunity to undertake a site visit to view the works as they progressed. Outside of this, carbon reduction measures were employed in the form of utilising eco-friendly site accommodation and reprocessing existing site materials. The project was registered with the Considerate Constructors Scheme, for which the team received a certificate of excellence for the level of performance achieved.

Antony Ballantyne, Southbay Operations Director commented ‘We are immensely proud at having been involved with a project that will support a more sustainable future for the North East region and beyond in the form of Dogger Bank Windfarm. The success of the project is testament to the hard work and commitment of the project team who maintained a proactive approach to all aspects of delivery’.

“This is another chapter complete in the Port's transition to a greener future," commented Mark Stoner, Chief Financial Officer of Port of Tyne. He added: "The quay strengthening at Tyne Dock is a fundamental building block in enabling the site for further development of the 200-acre Tyne Clean Energy Park to service the growing offshore green energy market in the North Sea. The use of low carbon delivery techniques adds to the substantial emission reduction measures we have put in place in recent years as we pursue our goal of being a carbon neutral port by 2030."
