[Shanghai: Accelerate breakthroughs in key technologies such as deep-sea sensors, ocean communication and navigation] On November 10, the Shanghai Municipal Ocean Bureau issued the "Shanghai Marine Economic Development "Fifteenth Five-Year Plan" Implementation Plan. It mentioned that the equipment system for polar scientific research and resource development should be improved, the research and development of deep-sea energy equipment such as deep-sea oil and gas development and deep-sea wind power should be strengthened, and marine nuclear-powered merchant ships should be proactively deployed. Promote the development of core equipment such as deep-sea mining ships and mining vehicles. Accelerate the development of marine carbon capture, utilization and storage technology, carry out technical research on marine carbon sequestration mechanisms, ways to increase sinks, promote the application and promotion of ship carbon capture systems, and develop key equipment for carbon storage. Support the research and development of engineering technology for extraction and preparation of active substances from deep-sea polar biological resources. Relying on core advantages in deep diving, deep drilling, deep netting and polar fields, we will explore multi-disciplinary integration innovations in marine science, bioengineering, life science, materials science and energy engineering. Accelerate breakthroughs in key technologies such as deep-sea sensors and ocean communications and navigation. Promote the construction of deep sea and polar biological resource databases. Deepen the integrated application of artificial intelligence in deep-sea communication and navigation, deep-sea intelligent exploration decision-making, and efficient development of biological resources.
