Port Dampier Port Expansion Mediation Survey for Boskalis and Van Oord marine contractors, 2007.
During the Port Dampier port expansion, significant differences were noted by the dredge contractors between the actual seabed conditions and those described as a result of geophysical surveys undertaken by the consultant. In order to minimise further downtime and optimise the dredging, the client requested Demco to complete an Aquares survey of the area.
The Aquares survey successfully distinguished between the calcarenite capping, Granophyre Basement and soft sediments. Following the study, the contractors were able to provide the consultant with a realistic estimate of time and cost for dredging operations.
