Project Description
The Problem: Aberdeen Harbour was operating at capacity and with physical constraints in the size of vessels that it could accommodate.
In 2010 Feasibility Studies commenced to review possible solutions. Ultimately the decision was to develop a new facility at Nigg Bay to the south of the existing harbour. This is not a replacement for the existing facilities but is an expansion capable of accommodating larger vessels up to 300m and deeper drafts of up to 10.5 at the deepest berth.
The new harbour will ultimately provide approximately 1400m of quays and 124,000m2 of laydown area. The Harbour is being formed by construction of two breakwaters each over 600m long. The breakwaters comprise rubble mound cores with rock armour layer and precast armour units ranging from 8m3 to 12m3 There has been approximately 2,700,000m3 of dredging required which included significant quantities of hard rock which was removed using some the world’s largest dredging plant to rip the rock. The quays are formed by a mixture of open and closed structures to satisfy wave modelling undertaken to ensure minimal downtime to operations. The Open quays will be precast structural decks constructed on 1500diameter piles and Closed Quays constructed using precast concrete caissons constructed in Spain. The use of the caisson units has enabled the harbour to expand its heavy lift capacity beyond initial expectations.
The development site was a largely undeveloped bay constrained by; a Site of Special Scientific Interest on the cliffs, presence of dolphins outwith the bay, rare plant species and the presence of the main sewage treatment plant serving Aberdeen and Aberdeenshire with two sewage outfall pipes, one of which runs below the proposed southern breakwater. Environmental Considerations have been a major influence on the planning, design and construction of the development.
