In December 2013 Deploy Subsea were commissioned by the Port of Melbourne Corporation to carry out PEER System inspections of a number of timber piles supporting Victoria Dock Melbourne. The purpose of this inspection was to conduct integrity trials of the system. The PEER System, designed by Foreshore Technologies in Vancouver Canada, is a diver operated ultrasonic timber pile resonator or ‘cavity detector’ brought to Australia in 2009 under a joint agreement between Transfield Services and Deploy. Deploy Subsea has carried out numerous inspections of structures supported by timber piles on behalf of the Department of Transport throughout WA.
