近年来,我国南海的领海问题争端不断,多数岛礁被越南、非律宾等国家占为己有,美、日等域外力量虎视眈眈。为应对南海的严峻形势,研发一种轻便型的多功能模块化足组合式海上军事基地——“守卫者”。“守卫者”由中心基地和六个功能性模块组成。固定式中心基地建立在水下暗礁基础上,采用类似导管架插桩的方式固定于暗礁,共分为四层甲板。功能性模块采用半潜式大型浮式及船型浮体,主要包括三个民用模块(石油生产/储存/补给模块、气候/海洋环境监 In recent years, disputes over the territorial waters in the South China Sea have continued. Most islands and reefs are dominated by countries such as Vietnam and the non-Philippine countries, and the United States, Japan and other extra-territorial forces are eyeing themselves. In response to the grim situation in the South China Sea, a handy modular multi-purpose modular military base at sea called “Guardian” was developed. The Guardian consists of a central base and six functional modules. The fixed center is based on the underwater reef, and is fixed to the reef by means of the similar jacket-inserted method. It is divided into four decks. Functional modules are semi-submersible large-scale floating and ship-type buoys, including three civilian modules (oil production / storage / replenishment module, climate / marine environment monitoring
