McLaughlin & Harvey at Nigg quay: design and load notes for port engineers

30 Second Briefing
Maraen Port of Nigg has awarded McLaughlin & Harvey a £30m contract, supported by a £10m Highlands and Islands Enterprise grant, to build the Eastern Inner Dock Quay (EIDQ) to service Scottish offshore wind projects. The works will focus on heavy-duty quay construction and ground-bearing capacity upgrades to handle large turbine components and installation vessels. For civil and geotechnical teams, the project signals continued demand for high-capacity quayside foundations and pavements tailored to offshore wind logistics in constrained dock environments.
Technical Brief
- Works are targeted at handling offshore wind components, implying very high point-load and axle-load design.
- Ground improvement and surfacing will need to accommodate crawler cranes and self-propelled modular transporters.
- Design will likely integrate deep foundations or load-transfer platforms to minimise differential settlement under heavy lifts.
Our Take
McLaughlin & Harvey’s recent £107m Port Ellen ferry terminal win and this Eastern Inner Dock Quay work both deepen its Scottish marine infrastructure portfolio, signalling that ports and quays are becoming a core revenue stabiliser after the procurement-driven turnover drop reported in late 2025.
The £10m Highlands and Islands Enterprise grant at Nigg underlines how Scottish public agencies are now co-funding strategic quayside upgrades, which in our database tends to accelerate follow-on private investment in offshore wind fabrication and staging capacity.
Across our infrastructure coverage, McLaughlin & Harvey is one of the few contractors simultaneously delivering heavy industrial facilities (e.g. Sheffield Forgemasters’ 30,000 m² machine shop) and complex marine works, a combination that positions it well for integrated port–manufacturing hubs serving offshore wind in Scotland.
