At present, the construction of ocean information has become an important support for national strategic aim of building an ocean power. However, the problems like the lack of unified planning, serious homogenization, isolated information, not enough wisdom in the construction process become increasingly evident. Starting from the idea of the integrated planning and construction, this paper puts forward a scheme of smart ocean engineering construction based on human body theory and the modern information technology of Internet of Things, Big data and artificial intelligence. This scheme completely designs the three-dimensional monitoring system of ocean environment, big data platform of ocean, the ocean application system as well as the information standards and norms, and other aspects. This scheme covers multiple business categories such as the ocean environmental protection, disaster prevention and mitigation, seas and islands, ocean law enforcement, ocean economy, and ocean fisheries. The results of this research are applied in the construction of smart ocean in coastal provinces and countries. Besides, it is of great significance to the construction of smart ocean in other coastal provinces and countries.
