Global Energy constructed a new quay wall and finger pier to promote an increase in work for the Nigg Energy Park. In front of the new quay, the seabed was deepened to -12m CD to accommodate the larger offshore vessel and rigs.
McLaughlin & Harvey was the main contractor for the construction of the quay wall and the dredging works and infill works were undertaken by Boskalis Westminster as a sub contractor.
The first phase of the works involved the dredging at the Nigg South Quay Development using the trailer dredger WD Mersey. The material was pumped ashore in the Finger Pier and stockpile at the Nigg Energy Park, with the remainder of the material discharged at the "Sutors" offshore licensed Marine Disposal area.
The second phase involved the dredging of Nigg South Quay Development to final design level using the larger trailer dredger Causeway. The material was pumped ashore in Invergordon behind a new quay wall constructed by McLaughlin & Harvey with the remainder of the material from Nigg disposed at the "Sutors" licenced disposal area.
