IN Brief:
- Maraen Port of Nigg has awarded the Eastern Inner Dock Quay contract to McLaughlin & Harvey.
- The £30m-plus project will deliver around 16,000 sq m of heavy-duty quay space and additional Ro-Ro capability.
- The investment supports Scotland’s offshore wind supply chain and wider energy-port construction capacity.
Maraen Port of Nigg has appointed McLaughlin & Harvey to deliver the Eastern Inner Dock Quay, advancing the next phase of infrastructure expansion at one of Scotland’s key energy ports.
The project represents investment of more than £30m and will create a new heavy-duty quay of approximately 16,000 sq m. The works will also add further roll-on/roll-off capability, strengthening the port’s ability to handle large energy-sector components and complex marine logistics.
Construction preparations have started on site. The development is supported by a £10m grant from Highlands and Islands Enterprise, forming part of the Scottish Government’s commitment to invest up to £500m over five years in Scotland’s offshore wind supply chain.
The Eastern Inner Dock Quay will modify the existing rock revetment on the east side of the inner dock to form a new heavy-duty quayside. Additional capacity is intended to improve operational flexibility at a port already used for offshore wind, oil and gas, nuclear, fabrication, marshalling, and logistics activity.
McLaughlin & Harvey has worked at Nigg before, having reconstructed the South Quay between 2014 and 2015. That package included a new combi-pile quay wall and a West Finger Quay, giving the contractor direct experience of the marine environment and operational constraints at the site.
Offshore wind construction is placing new pressure on ports across the UK and Europe. Larger turbines, heavier foundations, longer blades, and higher installation volumes are changing the specification of quay walls, laydown areas, lifting zones, storage space, Ro-Ro access, and grid-facing infrastructure.
Ports are increasingly being treated as construction platforms rather than passive logistics nodes. Components need to be manufactured, stored, assembled, marshalled, lifted, and transferred through facilities that can cope with significant point loads, tight installation schedules, and weather-sensitive marine operations.
For Scotland, quay capacity is closely tied to industrial strategy. Offshore wind project awards can support manufacturing, marshalling, maintenance, and service work, but those opportunities depend on whether domestic port infrastructure can handle the scale and rhythm of deployment.
The Nigg scheme sits alongside wider investment in long-life infrastructure that is being adapted for new industrial workloads. On the Main–Danube Canal in Germany, a STRABAG-led team is delivering a €380m replacement lock project, showing how energy, freight, and industrial systems depend on civil assets being renewed before wider policy ambitions can be delivered.
Marine civil engineering carries a different risk profile from conventional building work. Ground conditions, tidal windows, corrosion protection, environmental controls, lifting interfaces, vessel access, piling, temporary works, and live port operations all shape programme and cost.
Energy-port projects add further complexity because the components moving through the site are large, expensive, and schedule-critical. Delays to quay availability can disrupt manufacturing, marshalling, installation vessels, grid connection programmes, and wider renewable energy milestones.
The Eastern Inner Dock Quay will add capacity at a point when the offshore wind sector is trying to convert project pipelines into repeatable delivery. For the UK construction market, the award is another reminder that the energy transition depends on heavy civil engineering long before turbines reach the water.
