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.
The ROV Innovations Inspection team flew up to Mackay on Wednesday with Brian from Neptune Marine to assist SunWater in the inspection of some of their underwater assets an Eungella Dam. The Inspection consisted of two components, initially looking at the sealing of one of its outlet pipes, and secondly finding and inspecting a submerged concrete pipeline outlet tower.
The combination of the High Definition Sony camera in the ROV, additional LED lighting, as well as the VisionClear video enhancer, allowed the Sunwater engineers to confidently assess the situation 35m below on the dam floor. Our Imagenex positioning sonar also enabled us to quickly and efficiently locate the submerged intake tower that rose up to 28m depth, something that prior inspection companies couldn't locate due to the original tech drawings of the dams construction being inaccurate.
Due to the enhanced video feed, HD video, and Sonar, we were able to complete all aspects of the inspection and provide a live view of the assets to the SunWater Engineers. The dam inspection was completed within 4 hours, with the SunWater team being extremely impressed with the ROV and all tech provided by the ROV Innovations and Neptune Marine collaboration.
ROV Innovations was called to inspect the drilling of a tailings pipeline for the Newcrest Gold Mine on Lihir Island, Papua New Guinea. After drilling down approximately 120m to a depth of around 90m, the drilling team encountered some unknown parameters and required a high definition video of what the Auger encountered. Being able to quickly mobilise, the team form ROV Innovations was on Lihir within a couple of days and sent the 300F Seamor High Definition ROV to work.
Once high definition ROV footage was recorded and viewed real time by the drilling crew, they were able continue drilling with minimal downtime and expense.
While on Lihir, we put the ROV to good use, going offshore to inspect the position of the existing tailings pipeline, as well as inspecting the underground topography where the new pipeline was to emerge. While the ROV was diving off Lihir for the underwater inspection, we managed to video some awesome geothermal activity at 160m depth, with plumes of volcanic ash rising approximately 15m from the seafloor. Footage of the dive can be seen below -
ROV Innovations provides High Definition underwater footage for industries such as Marine Conservation and Research, Australian Biosecurity, Customs, Documentary and Film Makers, Oil and Gas industries, and AQIS to name a few.
