Maraen Port of Nigg Eastern Inner Dock Quay
Maraen Port of Nigg has awarded McLaughlin & Harvey the construction contract for a new heavy-duty Eastern Inner Dock Quay. The £30 million-plus investment will create about 16,000 m² of quay area, add roll-on/roll-off capacity, and connect the adjacent Sumitomo Electric high-voltage cable factory directly to cable load-out and export operations.

Project anatomy
Scope, counterparties, and execution logic
- Client / authority
- Maraen Port of Nigg
- Delivery parties
- McLaughlin & Harvey
- Contract route
- Owner-awarded construction contract within a £30 million-plus port investment, supported by a £10 million Highlands and Islands Enterprise grant; the contract price, bidder field and detailed commercial terms are not disclosed
- Execution window
- Final investment approval was announced on 26 March 2026 and the construction award on 28 May 2026, when the owner said site preparations had commenced. Construction completion, handover, commissioning and first cable export are not dated in the current disclosures.
- Works package
- Modify the existing eastern inner-dock rock revetment into a vertical retaining-wall, heavy-duty quay covering about 16,000 m²; provide additional Ro-Ro capability; and create a dedicated load-out and export interface for high-voltage cables manufactured at the adjacent Sumitomo Electric facility.
- Marine interfaces
- The delivery chain joins revetment conversion, retaining-wall and quay construction, berth and mooring geometry, heavy-load pavement, Ro-Ro access, cable-handling routes, load-out engineering, cable installation vessels, and safe construction inside an operating energy port. The public record does not identify a separate dredging package or accepted berth depth for the new quay.
- Commercial read
- The award converts a consented port plan into an executable civil package and anchors a specific cable-export use case. Supplier demand spans marine civils, heavy-load and Ro-Ro interfaces, mooring and fendering, cable logistics, temporary works, commissioning and vessel coordination. Revenue or operating performance still depends on physical completion, load testing, berth acceptance, cable-factory output, vessel readiness and the first documented export operations.
- Next milestone
- Track visible marine-civil mobilisation, retaining-wall and quay construction, disclosed completion timing, Ro-Ro and heavy-load acceptance, mooring and berth commissioning, interface readiness with the Sumitomo factory, and the first evidenced cable load-out to an installation vessel.
Material change register
What changed, when, and what it proves
Only source-bound events that alter phase, scope, counterparties, delivery, completion, commissioning, or acceptance are listed. A change can advance the record without proving the next gate.
Maraen awarded the construction contract and began site preparations
The owner named McLaughlin & Harvey for the Eastern Inner Dock Quay and said site preparations had commenced. The award establishes the delivery contractor and an early site state; it does not disclose the construction-contract price or prove retaining-wall installation, quay completion, berth acceptance, or cable load-out readiness.
Read controlling sourceFinal investment moved the consented quay into funded delivery
Maraen announced the £30 million-plus final investment after securing planning consent and the marine licence, with a £10 million Highlands and Islands Enterprise grant. The decision funded the project boundary but did not establish physical marine works, completion timing, or accepted operating capacity.
Read controlling sourceHIE approved up to £10 million of public support
Highlands and Islands Enterprise linked its support to the heavy-duty quay and Sumitomo cable-factory export route. The funding commitment established public backing and the intended industrial use; it was not a construction award, evidence of grant drawdown, or proof of cable-export operations.
Read controlling sourceThe marine-licence proposal exposed the quay-wall concept
The owner described converting the existing eastern inner-dock rock revetment into a vertical retaining-wall quay. The proposal defined the marine-civil concept, while approval, final investment, contractor appointment, field execution, and acceptance remained separate later gates.

Maraen Port of Nigg's 28 May 2026 announcement confirms the McLaughlin & Harvey construction award, a total investment above £30 million, about 16,000 m² of heavy-duty quay, additional Ro-Ro capability, dedicated high-voltage cable load-out and export use, and commencement of site preparations. Maraen's 26 March final-investment announcement confirms that planning consent and the marine licence were secured and identifies a £10 million Highlands and Islands Enterprise grant. The owner's March 2025 marine-licence notice defines the revetment-to-vertical-wall concept. HIE separately identifies the Sumitomo factory and the port as its primary export route, while McLaughlin & Harvey confirms its contractor role. These records do not prove quay completion, contract value, accepted berth geometry, commissioned Ro-Ro operations, cable-factory production, or a first cable-installation-vessel load-out.
Phase: construction. Evidence reviewed: 16 July 2026.
