In April 2014 Transfield Services contracted Deploy Subsea to carry out inspections of Department of Transport Navigational Aids in the Swan and Canning Rivers as part of an Asset Management Plan.
Using aerial shots, Maris ID numbers and GPS coordinates the divers were able to mobilise quickly using a small dive support vessel with diving spread to carry out the inspections according to the scope. In addition to the visual inspection, the divers carried out ultrasonic inspection on several of the timber piles using the PEER System and a number of the piles also had protective wrapping applied.
A detailed report was then provided to the Client once the inspections had been completed.
