The purpose of this study was to develop End-Closure Systems for Undersea Concrete Pressure Resistant Hulls. These End-Closures must seal and lock concrete cylinders ranging from 20 to 60 ft. in diameter. They must be removable permitting full access when the cylinders are located on the ocean floor in 1000 ft. of water and when the cylinders are located on land. The study considers End-Closure configuration including geometry and material, actuation or handling methods and sealing and locking alternates. Areas requiring additional research and development are identified. Author
