[Shanghai: Accelerate the development of ocean observation equipment, marine satellite communications, underwater communication and navigation, etc., and promote the research and development and application of key equipment such as ocean sensors, ocean intelligent robots, and submersibles] On November 10, the Shanghai Municipal Ocean Bureau issued the "Shanghai Marine Economic Development "15th Five-Year Plan" Implementation Plan. It is mentioned that efforts will be made to promote the development of high-performance ship steel and offshore steel. Accelerate the development and application of high-performance alloy materials, corrosion-resistant and high-strength non-ferrous metal materials, and composite materials such as carbon fiber and alumina fiber. Expand the application space of green protection, marine anti-corrosion, anti-fouling and other functional materials. Promote the development of marine information materials such as deep-sea exploration materials and key materials for submarine cables. Explore the application research and industrialization of special-purpose materials such as new piezoelectric damping vibration-damping materials and intelligent visible-light stealth materials. Strengthen the construction of digital infrastructure in the marine field and accelerate the development of marine observation equipment, marine satellite communications, underwater communications and navigation. Promote the research and development and application of key equipment such as marine sensors, marine intelligent robots, and submersibles. Explore the development model of the ocean data industry, strengthen data collection, sharing, traceability, and security, study and build an ocean data trading platform, and promote pilot trials in the fields of ocean data resource confirmation, valuation, trading, revenue, and governance. Encourage the development of large vertical models in the marine field.
