CONTAMINATED ENVIRONMENTS

Locally owned and operated in Melbourne, East West Dive and Salvage is uniquely qualified to handle contaminated diving across Australia. Specialising in all aspects of contaminated diving, including both sewage and effluent diving, our experienced and professional team is available to mobilise at any time, even on short notice.

We efficiently and effectively complete works in contaminated environments, such as polluted waters, Sewage Treatment Plants (STP), Waste Water Treatment Plants (WWTP) and water with questionable quality or contaminates.

With at least one diving team usually working somewhere in Australia on any given day, we are able to offer a service to conduct works in contaminated environments working to the strict AS/NZS standards.

Our divers can safely enter contaminated environments and carry out a wide array of tasks, such as:

  • Airlifting and dredging
  • Inspections of areas with zero visibility, which cannot be viewed using ROVs
  • Installation and replacement of equipment
  • Measurements and surveys
  • Repairs and maintenance of mixers, aerators, diffusers, gates and other TP facilities
  • Search and recovery dives
  • And more
Making use of Kirby Morgan Superlights, as well as full contamination suits, we offer a truly complete service. All our equipment is fully water tested prior to use and is disinfected to the highest possible standards upon completion of the job.

Contaminated diving, or as some call it 'poo diving' is a cost-effective and practical alternative to isolating, emptying, cleaning, and disinfecting contaminated areas. Because this costly and impractical approach is often impossible, our contaminated diving service has a wide range of applications.

UNDER WATER & WET WELDING

East West Dive and Salvage employs an experienced weld team to conduct both above and below water welding operations including welding in wet environments. The team have accumulated over 12km of welding length since July 2015 conducting steel patch repairs to sheet pile wall and steel tubular piles, installation of continuity bar and anodes on Impressed Current Cathodic Protection (ICCP) systems, conducting repairs to ships, and other steel repairs.

The company holds a variety of Qualified Weld Procedures to which the weld team are coded to maximise cost efficiencies and lead times for structural welding requirements; these include 6mm and 8mm continual fillet welds in 2F, 3F and 4F position welds. Holding these WQP and codes means the lead time for most welding tasks is minimal.

The weld team is capable of water and waterside based operations.

East West Dive and Salvage also has CSWIP 3.1 and 3.2 certified divers to undertake non-destructive testing operations with Ultra sonic thickness testing (UTT) and Magnetic Particle Inspection (MPI).
