ROV innovations have become synonymous with underwater asset inspections, specifically with assets in zero visibility water. Our ability to image complex structures such as bridges, as well as mapping river beds and obtaining hi resolution profiles has allowed us to provide our clients with images of their structures that they have never seen before.
Our high resolution sonar is ideal for projects such as :
Our custom designed vessel - White Shark 1 - provides us with an ideal working platform for all of our underwater inspection and survey requirements. It has a large open back deck, full-length canopy for sun and rain protection, doors on the starboard side allowing us to operate close to the water's surface, echo sounder, side scan sonar, 2000w inverter for the safe operation of all 240v equipment, hi flow water pump, twin 150 horsepower 4 stroke honda outboards, GPS, as well as a stern underwater platform that can be lowered to assist in retrieving divers or equipment from the water.
By combining our Sonar Imagery with that of our High Definition ROVs we can offer the highest level of confidence to our clients. We can use the high resolution imagery from the sonar to map large areas, zoom into any sonar returns that show any suspicious activity, record its precise GPS location, and then send our HD ROV directly to the anomaly and get eyes on the target to have a definitive answer for our clients. This allows us to confidently survey 100% of the area in question and also offer our clients a 100% guarantee that nothing was missed.
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.

ROV Innovations has been called upon to intensively map local swimming areas for potential underwater hazards coming up to Summer in South East Queensland. Our team used our high resolution scanning sonar from our custom designed commercial vessel to map the first area in Wivenhoe Dam.
We were able to quickly and efficiently identify 3 immediate hazards in the yet to be opened swimming area with the sonar, and with swift action by our client, arranged our commercial dive team to enter and remove them. In this instance, the hazards proved to be red Cedar tree stumps standing a meter tall and approximately a meter in diameter, and a 5m long log on the dam bed. Using an underwater hydraulic chainsaw, we were able to remove the potential hazards to ensure that swimmers in the area would not injure themselves.
Due to the low visibility around the bed of the dam, the sonar proved to be the only reliable method to identify any potential hazards to swimmers. Using either Divers or ROVs in this instance would not be viable as they could easily have missed these hazards by a meter and not seen them. Only the high resolution scanning sonar allowed us to have 100% confidence that we had covered the entire area of concern.
By combining our multiple resources (in this instance - Sonar, Commercial Vessel and Dive Team) we were able to provide the client with an optimal solution with minimal downtime.
ROV Innovations sonar staff were called out early Thursday morning to assist with the search and recovery of an Audi Q5 that had mistakenly used a boat ramp on the northern end of The Gold Coast to launch itself into the water.
A manual search was attempted on Wednesday evening, however due to the failing light and high currents it was decided to utilise the MS1000 hi resolution scanning sonar technology to assist with finding the vehicle.
Within 5 minutes of setting up, we had located the "probable location" of the car, triangulated the precise position from the sonar screen, and directed one of our recovery divers to the area. On confirmation that we had found the vehicle, the Heavy Duty Tow Truck used its winch to pull the Q5 back to the shore.
Thanks to Allcoast Towing and Knights Heavy Towing for bringing us down to assist in their recovery of the vehicle. We hope to be able to assist with any future search and recovery jobs.
Hydro Tasmania contacted us for a project on one of their dams. Due to the recent flooding events that have hit all of the eastern and southern coast of Australia (a 1 in 200 year event), a significant volume of water was flowing into the northern lakes, discharging over several spillways Hydro Tasmania own and operate.
Due to the high resolution scanning ability of the Kongsberg MS1000, we were able to show extremely clear images of the dam structure that hadn't been seen in almost 60 years since the dam construction. Due to the water being almost Zero Visibility, prior commercial dives in the dam plunge pool only hinted at various issues underwater, the sonar imagery we collected allowed the Engineers and Hydrographers to see everything that was occurring.
Despite the environmental conditions, we completed the project without getting too wet and cold, and were able to provide a mosaic of the scans (as above) by the end of the day. The sonar scans gave Hydro Tasmania's engineers very useful information to assess the condition of the dam plunge pool..
We have recently conducted underwater and aerial condition assessments for 5 SEQWater potable reservoirs in Alexandra Hills, Narangba, and Ferntree in South East Queensland for GHD. The 5 potable water tanks were inspected over the course of three days, with strict sterilisation procedures being followed for all equipment entering the reservoirs.
As per our standard operating procedure whenever operating with potable water, all equipment was sterilised with 200ppm active chlorine and left to soak for a minimum of 30 minutes, including the ROV, all tether, ropes and tarps that were used to keep the ROV and equipment clean on the base as well as the roof of the reservoirs.
Our High Definition Seamor ROV enabled the GHD Engineers to confidently assess the underwater internal structures of the reservoir, including ladders, wall and floor joins, scours, probes, mixers, columns, and also any buildup of debris or sediment.
All of the inspections were completed on time and within budget, thanks to the organisation and planning from Rhett and Danny from GHD, as well as Russell from SEQWater. We look forward to conducting more inspections for them in the upcoming months.
David from Christopher Contracting contacted ROV Innovations to conduct an internal reservoir roof inspection for SEQ Water. With the ability for 2 high definition cameras to be deployed from our ROV, as well as 4 ultra bright LED floodlights, 100% of the internal roof was surveyed and inspected within the allocated time and on budget.
Once the project was completed and all footage checked for QA purposes, we then took a peek at the underwater assets in the reservoir to show Charles and the guys and girls at the SEQ Water WTP the condition of the asset.
Thanks to the friendly and courteous staff from Christopher Contracting and SEQ Water - we look forward to working with you both again in the near future.
The 15th and 16th February saw us down in the southern parts of Tasmania to conduct some ROV trials for Huon Aquaculture. Despite the weather, the trials went well, enabling us to see the conditions and environment the guys and girls at Huon Aqua work in, and allowed the staff and contractors there to see the versatility of the ROVs we can provide.
Some pictures of the trials can be seen below.
We look forward to working with Huon in the upcoming months to provide them with an ROV tailor made for their needs.
Wayne Griffioen from Tasman Geotechnics contacted ROV Innovations to assist with the possibility of surveying the extent of some flooded old coal mines in Northern Tasmania. The coal mine was discovered on some old maps of the area and was found whilst conducting standard boring to determine geological information of the area. The cave itself was only 800mm high, and located approximately 21m underground. They also had the equivalent water depth of 14m.
After discussions with Wayne on the different options available, we settled on using a combination of a high resolution scanning sonar (Kongsberg MS1000), and a small, lightweight ROV for further exploration. The original borehole was only 90mm in diameter, therefore it had to be increased to allow the equipment through the hole and into the coal tunnels.
Unfortunately, the positioning of the borehole on entry to the coal mine was off centre, therefore the sonar was situated within a small alcove in the cave, restricting the images of the western wall. However detailed measurements were gathered showing bends within the cave and also junctions where the mine branched in different directions. As the mine profiles were gathered every 100mm, we could determine the height, width and length of the coal mine section we were in and then compare this to the original drawings of the mine structure.
A Videoray Pro 4 was also on site to obtain video footage of the mine itself as well as explore the various mine tunnels. Unfortunately due to the extremely high turbidity of the water within the mine, the camera on the ROV was only useful for obtaining video of the various rock layers, as well as their geological structure.
The data from the MS1000 sonar allowed us to determine the best location for additional boreholes to allow the deployment of the sonar for further mapping of the flooded coal mine.
Thanks to Wayne Griffioen and Emily Bartlett from Tasman Geotechnics, as well as Simon Hills from Imbros for making this project run extremely smoothly despite the horizontal hail and extremely cold conditions on the day. We look forward to continuing the exploration of the coal mine once the additional boreholes have been drilled.
