走近大国重器 | 行走的蓝色粮仓

Core Viewpoint - The "Bay Area Lingding" is the world's first self-propelled natural water exchange aquaculture vessel, designed to enhance China's marine aquaculture capabilities and contribute to food security in a country with over 1.4 billion people [3][4]. Industry Overview - China is focusing on developing marine ranching and "blue granaries" to ensure food security, transitioning from traditional aquaculture to deep-sea, mechanized, and intelligent methods [3][4]. - The deep-sea aquaculture sector has seen rapid development since the introduction of gravity-type net cages from Norway in 1998, with significant investments in marine fishery technology [4][5]. Vessel Specifications - The "Bay Area Lingding" has a total length of 155.8 meters, a width of 44 meters, and a depth of 24 meters, with a maximum draft of 20 meters and a total aquaculture space of nearly 80,000 cubic meters, equivalent to the water capacity of 32 standard swimming pools [5][6]. - It can produce up to 5,000 tons of seafood annually, comparable to the output of 5,000 acres of land-based fish ponds [6]. Technological Innovations - The vessel features a self-propelling electric propulsion system and utilizes ocean currents for natural water circulation, reducing energy consumption and creating a near-wild growth environment for fish [5][6]. - Advanced technologies such as laser cutting, automated welding, and 3D modeling were employed in its construction to enhance manufacturing efficiency and quality control [8]. Environmental Considerations - The vessel is designed to operate 40 nautical miles from shore and can withstand typhoons up to level 12, using high-strength steel to resist harsh marine conditions [7]. - It incorporates a comprehensive energy system that prioritizes renewable energy sources, achieving 100% clean energy use during static operations, significantly reducing carbon emissions [9]. Smart Aquaculture Features - Equipped with underwater sensors and cameras, the vessel monitors water conditions and fish activity in real-time, allowing for precise feeding based on AI algorithms [10]. - The vessel can autonomously adjust its course to avoid adverse weather and optimize fish growth conditions, enhancing operational efficiency [11]. Future Prospects - The "Bay Area Lingding" aims to serve not only as a marine ranch but also as a tourism platform, offering fishing experiences and educational opportunities about deep-sea aquaculture [12]. - The development of such innovative aquaculture vessels represents a modernization of traditional fishing practices, contributing to increased supply of high-quality seafood and supporting China's food security strategy [12].
