Leith Outer Berth

GRAHAM, has engineered a landmark achievement in Scotland’s renewable energy sector, in collaboration with HBPW Consulting Engineers and Forth Ports Ltd – Scotland’s largest renewable energy hub in Leith. This 175-acre project, a testament to GRAHAM’s engineering excellence, is a pivotal asset in Scotland’s pursuit of net-zero emissions. Featuring a heavy-lift berth with a 100 t/m2 capacity, it’s designed to accommodate the world’s largest offshore renewables support vessels, directly enabling the Inch Cape wind farm and anchoring Leith as a cornerstone of the Forth Green Freeport.

The project involved the removal of an existing jetty, the installation of over 200 tubular piles, construction of six retaining walls, and the placement of 6,000m3 of reinforced concrete for a 125m x 28m suspended deck. We also executed extensive dredging, earthworks, and installed critical infrastructure, including ducting, drainage, and advanced electrical and fibre optic systems. The Leith Outer Berth, a direct result of our meticulous execution, now provides essential logistical support for the Inch Cape wind farm, facilitating the handling of monopile and jacket foundations. This vital infrastructure is a key component in Scotland’s ambition to achieve 11GW of offshore wind capacity by 2030. Our work has not only delivered a critical piece of infrastructure but also catalysed economic growth.
