ROV Innovations were contracted to complete the internal inspection of 2 pipelines, as well as the cleaning and inspection of the seaward assets, for the Desalination Plant situated on the Gold Coast. For the project, we utilised a long range Seamor Chinook ROV, outfitted with 2000m fibre optic tether, pipe profiling sonar, and 2 additional Hi-Def cameras. This allowed us to visually inspect all aspects of the internal pipeline with one pass. The pipe profiling sonar also allowed us to accurately measure the buildup of debris within the pipelines (if any) and report on the total cubic meterage within the pipe length.
The desalination plant had 2 pipelines that were required to be internally inspected. The intake pipe (2200m in length) and the outfall pipe (2050m). The oceanic intake dome, as well as the outfall diffusers were also inspected to ensure that no damage had occurred, the cathodic protection was operating as anticipated, and to also ensure that there was no environmental concerns from the running of the plant.
The external intake and outfall proved to be a veritable oasis for both tropical reef fish, sharks, rays and invertebrates, in an otherwise featureless underwater sandy desert. Corals (both hard and soft), ascidians, sponges, feather stars, brittle stars, anemones, and thousands of fish have all colonised the desalination plants oceanic structures creating a thriving underwater community.
Thanks to the great guys at Veolia for all their assistance throughout the project, specifically Alf Cosgrove, Terry Casey, and Filippo Vico. We look forward to working with you all again in the near future.
