meters, it endures factors including cold temperatures, bending, tension cycling, corrosion, marine abrasion, compression and even attack by sea-life. It must flex and bend to deal with winching, marine currents, and pressures exceeding 550 bar (55,000 kPa).Each cable provides the physical connection for real-time power and communication connectivity. Designs have to be rigorous, and manufacturing takes attention to detail and proven processes.Material gainsThe requirements for underwater sampling and monitoring are diverse. Projects can include seismic surveys, marine life studies and pollution tracking

structures. TMC software was also used to monitor and visualize deconstruction progress of submerged structures and bridge components. As deconstruction progressed to the removal phase, the survey vessel continually collected data and updated the existing 3D surface model, which was transferred in near real time to the machine fleet to provide the operators with updated views.“From our system, what the operator sees in the first phase is where the tool has been so that he’s getting proper coverage of the inner deconstruction process,” said Nash. “Once he feels he has reached a certain

alongside a multibeam echosounder (MBES).The survey time was half of what it would have taken using a traditional ROV to perform the survey and it could have been faster,” says Ward. “Such a survey is possible without a tether, but it was performed with a tether on this occasion so that real time data could be collected.”For navigation, the vehicle used USBL aiding to follow a route position list from as-built charts of the pipeline.  This can be combined with the autonomous pipe tracking algorithm which uses pipe profile data collected for the MBES to follow the pipe route.

of flow cytometric and video technology to capture high resolution images of suspended particles. Laser- induced fluorescence and light scattering from individual particles are measured and used to trigger targeted image acquisition; the optical and image data are then transmitted to shore in real time. Collected images during continuous monitoring can be processed externally with automated image classification software. Images can be classified to the genus or even species level with demonstrated accuracy comparable to that of human experts

. This particular model will be equipped with a handheld pendant controller, and a fiber optic tether multiplexer upgrade. These will help control a wide array of on-board instrumentation such as USBL underwater positioning system with GPS integration, the ROV to be tracked in real-world coordinates in real time, and an integrated Tritech Micron Echosounder which permits the ROV to measure its height above the seafloor and maintain its height with our auto-altitude system. This vehicle will also come with a dual function gripper, a sensor skid (which provides opportunities to integrate additional sensors

survey, it was important to capture not only the repeatable, accurate, millimetric details of the aircraft but also the substance and structures of the marine biomass on and around the aircraft. These challenges created a unique opportunity for 3D at Depth’s SL3 subsea laser LiDAR with its real-time 3D data processing unit. In addition, the team used still photography, 4K video, 3D photogrammetry, and 360⁰ VR.Over a period of six days on site, dozens of dives were conducted to the wreck located under 130 ft of water. Four registration markers were set in pre-approved areas to check accuracy

A SmallSat AUV Network

De Sousa leads an international network of AUV-keen scientists akin to NTNU’s. Both have highly evolved AUV labs. The three research communities have combined to make lasting AUV operations controlled or augmented by Micro or Nano satellites — SmallSats of 10-100 kilograms or 1-10 kg — a reality. Apart from the command and control of networked AUVS (and other drones) en masse, which is Prof. De Sousa’s specialty, it is hoped that SmallSats will do for ocean understanding and marine operations what the Internet did for marketing and instant knowledge.AUV control“Most of our

To measure these parameters Miros has installed their WaveWeather solution on the shore at Flaskebekk.WaveWeather consists of a highly accurate radar-based wave measurement sensor, The Miros RangeFinder (SM-140), paired with multiparameter meteorological instrumentation. The solution not only measures real-time wave data and water level, but also provides wind speed, wind direction, temperature and more. Dry mounting ensures that equipment is not impacted by the corrosive saltwater environment, the force of waves, floating objects or biofouling.The “Mini-Tsunami” PhenomenonUnlike normal

reality is here and becoming more advanced. As we move forward, we will build up 3D images of particular fields and other locations. Virtual reality is used on the surface, and its capabilities are expanding subsea. We are currently working on a project to enhance subsea 3D imaging capabilities in real time. You cut out the data processing so that the processing is done immediately. Looking for anomalies has historically been done post-processing, which takes up time and involves extra vessel days and personnel days. If it can be done on a real-time basis at the worksite, then it’s going to
