In a 24/7 operation, the Fairway super dredge lengthened the Lyttelton Port channel by approximately 2.5km and widened it by 20 metres and deepened it by up to two metres. The channel provides Canterbury’s importers and exporters the best possible and most-cost effective international shipping solutions.
Suction pipes moved across the seabed suctioning mud and silt into a hopper with a capacity of 36,000m3. Material was held in the hopper until full and then disposed of at an approved spoil ground located 6km offshore.
Lyttelton Port Company implemented the largest environmental monitoring programme ever undertaken for a New Zealand dredging project. 14 dedicated gauges deployed throughout the harbour and off-shore measured a range of factors including water turbidity, pH and temperature. The project included the installation of nine new marine based navigational aid towers, six land based navigational towers and six new spar buoys throughout the harbour.
