This panel is about bringing the science, the research work, and engineering of what is happening in the underwater environment together. The discussion will first shed a light on the available Oceanic Engineering resources such as communications, literature, technology reviews and tradeoff studies pertaining to all bodies of water. How it is possible to execute full scale tests or use simulations to test conditions that represent realistic marine environments. Describing how new capabilities are being created that can be brought to scale, and how the emerging technologies are being developed to solve for the existing challenges in the subsea ecosystem. Speakers will discuss the different channels, and applied research work to support transitional engineering for offshore technology development. The discussion will then go through the deeper water environment, describing the complex surface and subsea conditions, how the Metocean wind, wave, and climate conditions often impact the subsea structures attached to the ocean floor. The Hydrodynamic forces involved, and the associated Structural mechanics fatigue and degradation components, benchmarking the need for continuous structural health monitoring and limit state prediction. Speakers will highlight the problematic areas for ocean science and technology in particular environments such as Ultradeep water, under ice in the Arctic. They will also go through the ROV/AUV technologies and their limitations explaining the differences in size classification, depth rating, power sourcing options, and tooling kit suitability for different missions. The panelists will share oil & gas and renewables use cases such as inspection of subsea components such as risers and pipelines inspection, leak & corrosion measurements, and touch on the use of underwater drones for special military operations, such as contraband inspections, port security, search and recovery operation, explaining the deployment and control methods. Topics covered would include the need for autonomy to assess changes on the seafloor, during service operation. The use of fully or partially resident modes and the use of resident docking units as power source and means of communication back to surface as well as the effect communication system type on the degree of autonomy, explaining the multisensory data frequency and imaging requirements. Speakers will project future opportunities for improving ROV’S/AUV’s capabilities, such as the communication system, the navigation system, and the data requirements, via internet connection, wireless hotspots, or real time data streaming to close the loop for this ecosystem.
