Reliability and Safety Considerations in the Design of the Submersible LEO I

摘要

LEO I is one of the newest submersibles produced by International Hydrodynamics Company Ltd. While still maintaining the wide range of capabilities which have made the PISCES submersibles so successful, LEO I has been designed with reliability and safety as primary concerns. Many of LEO's reliability and safety features have been developed from over ten years of operations of the PISCES line of submersibles. Several new safety features are also included, such as; reduced floodable volume which eliminates the possibility of the submersible sinking if anything other than the personnel sphere floods; a highly reliable lead ballast system was developed; the pilot's field of vision was increased through the use of a large spherical sector viewport.
