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. ROV Innovations have recently conducted a thorough scanning sonar inspection of a creek crossing in Victoria for Sterling Group and Victoria Rail. The Kongsberg MS1000 high resolution scanning sonar was used due to the high turbidity of the creek which prevented any sort of visual inspection from being carried out, either by a commercial dive team or ROV. Multiple imaging scans were taken within the creek to show the bottom topography and indicate if there were any buildup of debris around the rail footings, and also to highlight any possible scouring. Due to the versatility of the Kongsberg MS1000 scanning sonar, creek profiles were also taken at multiple locations both longitudinally and transversely around the rail assets. This allowed a true profile of the area to be visualised, which in turn enabled the engineers to compile their structural report with an extremely high level of confidence High end equipment such as the Kongsberg MS1000 High Resolution Scanning Sonar enable traditionally difficult areas to be inspected and surveyed underwater. Areas with zero visibility and high currents (most Australian rivers) have traditionally been inspected with divers "feeling" the areas around the asset. This leaves extremely high levels of variation and increases the chance that areas are missed. The Sonar ensures that 100% of the asset and surrounding environment is assessed and mapped for the client, with minimum time taken and minimal OH&S risk as no staff are physically in the water. Thanks to David and Ben at Sterling for their assistance and hospitality, as well as Mark Atherton for his assistance with the MS1000

ROV Innovations recently conducted multiple internal fire tank inspections for FCF - Fire and Electrical clients PUMA Energy. PUMA had recently taken over multiple fuel stations on the Fraser Coast and required their fire deluge systems inspected to ensure that they complied with current legislation. Despite the 3 1/2 hour mobilisation each way to the 2 PUMA Energy sites, the inspections were all completed same day, and on budget. The high definition video footage and 12 megapixel images were compiled and sent off to FCF next day ensuring that they could quickly and efficiently compile the reports to PUMA with minimum turnaround time.
Attached are just some of the images provided to FCF for their reporting to PUMA Energy. ROV Innovations has just signed a formal contract with SunWater to conduct all of their Dam inspections for the next 3 years. We look forward to working alongside the SunWater staff, and to bring our advanced capabilities to assist them with their underwater asset inspections throughout Queensland.
Stay tuned for more information.... Orpheus Island Demo from ROV Innovations on Vimeo. This excerpt is from a recent trip to Orpheus Island Research Station with staff from Trinity Bay High School, James Cook University (JCU) and The Australian Institute of Marine Science (AIMS). It is filmed with a Seamor 300F ROV recording in standard definition. Visibility was between 3-4 meters, calm conditions, with the current picking up to approx 2 knots. The second part of the demo is filmed on a GoPro Hero 3+ mounted on the ROV to capture a perpendicular view to the sea floor. 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.
David Robinson, the Harbourmaster at Christmas Island, contacted ROV Innovations to complete inspections of their deep water moorings at Flying Fish Cove and the Smith Point refuelling facility. Working closely with commercial divers and engineers from Undersea Construction Ltd, we were able to inspect the deep water anchorages for the vessel moorings that were in 265m and 550m of water just off the Christmas Island coast. With the commercial divers inspecting the top mooring components and horizontal spans, the ROV concentrated on penetrating the deeper water to inspect the chains, wires, shackles, dumpers, and anchors of the moorings themselves. With additional modules on the Seamor ROV such as a Cygnus ultrasonic thickness probe, and Tritech underwater positioning system, additional information on the underwater assets was available including actual position of the anchor allowing the engineers to determine if the system had moved from its first position. Thanks to David Robinson and Neil McNeil at Christmas Island for their great support and hospitality, as well as Wayne and Dave from Undersea Constructions Ltd.
