The Scottish business unit of civil engineering contractor BAM Nuttall is the main contractor for the $18.43-million program to lengthen the quay by 75 m to 130 m (246 ft to 426 ft).
The extended quay should provide deepwater, berthing and heavy load-bearing capacity of 60 metric tons (66 tons)/sq m to take an offshore structure in a single lift, with an expanded laydown area. It will have 12.5 m (41 ft) water depth alongside, one of the deepest for any quayside in Scotland.
Work on the project starts in April and should be completed within a year.
The extension will be complemented by an increased, adjacent laydown for equipment and materials which should reach 45,000 sq m (484,376 sq ft) by 2016.
