AUS-ROV were successful in their bid to perform an inspection for AdelaideAqua at the Adelaide Desalination Plant. The lads used the very capable SeaBotix vLBV300 High Definition ROV to complete the inspections of the onshore and offshore intake and outfall risers and tunnel entries. The offshore work was carried out in 20 knot winds with conditions worsening through the day. AUS-ROV and the team at Whyalla Dive Services kept the project moving at steady pace with their experience at this site proving advantageous. The video below portrays some insight into the project.
Another offshore deep sea project has been carried out by AUS-ROV, this time performing works as part of an environmental monitoring condition for a mine in remote Papua New Guinea. The pipeline which releases tailings at a depth of 150m and drops off to 300m has to be inspected to ensure that there are no leaks above the Surface Mixed Layers consisting of the Euphotic Zone Depth (UZD @ 80m), Upwelling Depth (UWD @ 100m) and Mixed-layer Depth (MLD @ 120m). Sediment sampling and continual monitoring for environmental impacts are something AUS-ROV personnel are passionate about and an intimate association with environmental assessors involved in this particular project will be an ongoing focus.
AUS-ROV's Adrian and Alex Jahnke achieved 1380m of tunnel inspection at Adelaide Desalination Plant recently. The inspection was to identify if the chemical lines cover plates were still in tact since operations started a few years ago. The client was pleased to see this was the case and can rest assured that divers will not need to be called in to perform maintenance works. The inspection was carried out using a SeaBotix LBV300 with 750m of fibre optic umbilical. The tunnel was accessed from both offshore and onshore ends and allowed for approximately 1400m of horizontal tunnel to be inspected. AUS-ROV have just upgraded to a vLBV300 and are expanding our tunnel inspection capacity considerably. If you are in a position where your flooded tunnel needs inspection, AUS-ROV are the experts in Australia.
Visual inspection of a seawater inlet tunnel which feeds West Lakes, South Australia has been executed by AUS-ROV special operations unit. A crane was met on site to lift the 6.5t concrete lid for access to the tunnel. AUS-ROV deployed the LBV300/4 full fibre optic system with 750m of tether on hand winch. The ROV Pilot then 'flew' the ROV to the offshore intake riser 700m seaward of the access shaft. Additional 1080 Lumen LED external lights and the ROV's high resolution camera resulted in quality video footage for identifying in fine detail the current condition of the internal surface of the 3.5m diameter tunnel. This was the first inspection carried out in 36 years and the client was pleased the structural integrity remains un-compromised. Further to this AUS-ROV Environmental Scientist Adrian Jahnke identified several fish species inhabiting the tunnel, concluding that this water asset not only provides clean seawater to West Lakes tidal ecosystem but a safe habitat for fish to occupy.
AUS-ROV and ROV Downunder performed an ROV general visual inspection (GVI) on Little Nerang Dam in the Gold Coast Hinterland on Thursday, November 23, 2014. Previous inspections conducted by commercial divers failed to locate the last of five 90 degree upward facing intake valves that protrude from the concrete dam structure. Using a Tritech Micron Imaging Sonar, AUS-ROV Operations Team were able to locate all five of the bell mouths and provide visual confirmation on their integrity and blockage status. The project team also investigated the dewatering valve gate and confirmed what divers were not able to see on previous inspection. SEQ Water Management responsible for the operation of this dam were pleasantly impressed with the SeaBotix LBV200's video quality and ability to capture critical information which strongly defines the scope of works required to ensure the City of Gold Coast has access to clean drinking water captured in the pristine hinterland of the Gold Coast.
Tony Bramley of Whyalla Dive engaged AUS-ROV to perform an ROV inspection on a disused mussel lease in Wallaroo, SA. The weather was perfect and visibility was around 20m which allowed for some great filming. The concrete blocks that make up the lease are positioned in grid form and connected by ropes. From the ROV footage we were able to determine the extent to which the infrastructure is still in tact and what method of removal can be used to clean up the site and make it more eco friendly. Some local dolphins came in to say g'day also, making for some great footage.
AUS-ROV have made a name for themselves in the Middle East, successfully capturing over five hundred UT spot readings across the steel base of Petromasila's 30m diameter, 20m high and 13ML capacity fire water tank. AUS-ROV used their remote vacuum system to clean sections of the tank where heavy sediments were encountered. This allowed for AUS-ROV to confidently inspect approximately 80% of the tanks base with random spot thickness checks. This fire tank has been in constant service for over 20 years and cannot be taken offline and drained due to the need to protect the crude oil tanks in the event of a fire. This was one of the most satisfying projects attempted to date for AUS-ROV personnel
AUS-ROV recently won a contract to provide ROV services for a local benthic habitat survey. The project involved mobilising a survey vessel and ROV to the inshore waters of Gold Coast from Miami up to Southport. Areas of interest included Mermaid Reef, Narrowneck Artificial Reef and the Wreck of the Scottish Prince located just out front of Marina Mirage in Southport. The survey included 24 x 100m transects and a 'fly over' narrowneck reef and the Scottish Prince. We can assure you that the inshore waters of the Gold Coast are alive and flourishing with an immense diversity of flora and fauna.
AdelaideAqua recently engaged Whyalla Diving Services and AUS-ROV to perform an internal visual inspection of the Adelaide Desalination Plant's Seawater Intake Structures. The project was carried out in extremely perfect weather conditions with great visibility. AUS-ROV's Seabotix LBV200 was the perfect lightweight ROV for mobilising to South Australia and successfully penetrated the tunnel to the limit of it's 250m tether. AUS-ROV specialise in Desalination Plant Sea Water Intake and Outfall Infrastructure ROV Inspections and can develop any technology our customers require for ensuring their water assets are maintained in good working order.
AUS-ROV have performed a 650m internal pipeline inspection recently on behalf of Trility Water. This full length pipeline inspection of the 400mm diameter seawater intake pipe provided engineers a close visual insight into the condition of the pipeline and answered integrity questions relating to critical components of the intake structure. AUS-ROV delivers final written reports detailing their findings on all civil structures they inspect. AUS-ROV received credit from the client on the professional and successful completion of the project. AUS-ROV are established experts in the field of tunnel and pipeline investigations.
AUS-ROV R&D developed a remotely operated vehicle vacuum cleaning system for water tanks which allows tanks to be kept online whilst sediment is being removed. The system incorporates a custom made vacuum suction head fitted to the Seabotix LBV200 ROV. The tank floor is remote control cleaned using this system which saves water, eliminates confined space entry, and only requires two personnel to carry out the operation. Thickness testing of a steel water tank's floor and shell can then be achieved by ROV UT Instrumentation.
AUS-ROV received a call advising that a friend had jumped approximately 20m from a tree above a cliff into a waterhole at Dalwood Falls, NSW and failed to surface. AUS-ROV quickly mobilised their Seabotix LBV200 ROV and 3 jaw mechanical grabber to the site of the incident where NSW police officer gave permission to attempt search and recovery operations. As the full moon rose over the water AUS-ROV conducted ROV search of the waterhole. At 9.20pm the body was located at a depth of 7.4m. The 3 jaw grabber took a firm grip of the body and returned to the surface. AUS-ROV would like to thank all NSW Police and SES personnel involved in the operation.

Adrian and Alex Jahnke of AUS-ROV Underwater Inspections celebrated the completion of a successful second year of operations in the ROV industry. To add to celebration on the day AUS-ROV were awarded contracts from both Shell Australia and Veolia Water. In two years AUS-ROV have achieved a solid footprint in the ROV market and specialise in water tank inspections, pipeline surveys, marine surveys, tunnel inspections, vessel hull inspections and sub marine infrastructure inspections. AUS-ROV Directors extend a huge thank you to our collaborative partner, Bill Bulloch of ROV Downunder for his continued support from his offshore postings.
AUS-ROV and ROV Downunder collaborated with Veolia Water to execute this inspection of the Gold Coast Desalination Plant's filtered seawater tank. The footage was captured in high definition 1080p video providing significant detail of the internal condition of the water tank and it's components. AUS-ROV have been providing the highest standard of remotely operated underwater vehicle services for over two years at the Gold Coast Desalination Plant and look forward to the next inspection which involves a pipeline crawler system in a dry tunnel.
With days notice AUS-ROV mobilised an ROV system and team from Perth to Bunbury and meet up with Kurt Haunold and J Cortez of Harbour Services Australia and loaded our equipment onto their launch vessel Harbour Achiever and headed to sea to inspect the anchored and awaiting Stenaweco Spirit . The propeller, 6m diameter propellor and rudder were inspected first followed by passes of the port side, starboard and undercarriage checking for damage, anti-fouling condition, marine growth and condition of the bilge keels and sea chest grates, fasteners and mousing. The inspection was completed in under 7 hours and the HD footage provided the owner a clear picture of the state of their vessel hull.
AUS-ROV Underwater Inspections not only inspect fire water tanks and drinking water reservoirs but also provide maintenance services such as dive cleaning and tank refurbishment. AS 1851-2012 Routine Service of Fire Protection Systems and Equipment specifies that Fire Water Tanks must be cleaned 12 months after commissioning, when the tank base is covered in sediment to a level determined by a suitably qualified tank technician to require cleaning or at a maximum interval of every ten years. It pays to shop around when looking for tank or reservoir cleaning services. Always make sure the people you engage are ADAS Australian Diver Accreditation Scheme approved.
This sixty year old weir in the Atherton Tablelands was losing water through a corroded drain valve. SunWater engineers decided to plug the drain with a quick forming grout. The strong suction force at the intake made it unsafe for a diver to conduct work. AUS-ROV were able to use the three jaw grabber on the SeaBotix LBV200 to grip the grout injection hose and hold it at the entrance to the drain intake whilst the grout was injected. AUS-ROV can provide underwater construction support in all types of aquatic environments. We have a comprehensive spread of ROV's and Subsea Tooling available.
This month the team at AUS-ROV were safety inducted to work on Shell Petroleum sites throughout Australia. The first assignment was an ROV Fire Water Tank Inspection of the internal condition of the fire water tank at the Brisbane Shell Distribution Centre. The inspection provided strong evidence to support the health of the tank structure and allowed the Tank Integrity Engineers to determine the maintenance and further inspection requirements of the tank using the High Definition Video taken of the entire internal surface of the tank. AUS-ROV will be performing inspections throughout Australia on behalf of Shell Petroleum. Fire Water Tank Inspections are required under legislation for Fire Service Maintenance.
