From September 2012 to July 2013 DEPLOY Subsea were contracted by Maritime Constructions to provide a variety of specialist underwater works on the Elizabeth Quay Development Project in the City of Perth.  The works involved the decommissioning of Jetty 6 which required cutting of steel piles in near zero visibility. The piles were then lifted onto a construction crane barge. Other work on the project included underwater video survey to locate any anomaly, installation of protective wrapping to a number of steel piles, cutting and removal of a number of timber piles using hydraulic underwater chainsaws and underwater welding.
