This project collects, analyzes and studies on the specification, standards and technical requirements for the entry and egress system of domestic and international diving and underwater operation in the aspects of design, construction and application.By researching on the current status and trends, industrial demand, as well as technical requirements at home and abroad, this study finds out the gap between domestic and international requirements, proposes the countermeasures, and forms a standard framework for domestic diving and underwater operation entry and egress system.Meanwhile, on the basis of the practical demands of domestic market and safety requirements, two transportation industry standards, Diving Basket, and Launch and Recovery Devices of Entry and Egress System for Diving and Underwater Operation, are made to accelerate the connection with international diving and underwater operation and to enhance the domestic market competition as well as the overall industrial safety level.
