Integrating MIL-STD-882 System Safety Products into the Concurrent Engineering Approach to System Design, Build, Test, and Delivery of Submarine Systems at Electric Boat

摘要

In 1989 Electric Boat initiated an Integrated Product & Process Development (IPPD) process for its design and development of submarines and submarine systems for the U.S. Navy. This approach is accomplished through the use of integrated Design/Build Teams that include representatives of the Government (customer), the fleet (user), designers, builders, testers and sub-contractors. Design/Build Teams are organized to support ship areas and ship systems and its membership has a strong technical base. The team members are experienced systems and safety engineers, fleet personnel and management decision makers enabling the team to quickly respond to design, construction, safety or user concerns. As the IPPD process evolves from concept to construction, the Design/Build Team focus shifts from design and development to operations, supporting effective integrated ship construction test and outfitting. This paper describes the safety engineer's membership role in the functional ship area and system-based Design/Build Teams at each phase of development from concept through design, construction, test, and delivery. Specific attention is directed to how system safety engineering at Electric Boat has adapted the traditional series of MIL-STD-882 System Safety Hazard Analyses to support the dynamics of the Design/Build Team concept. We discuss the system safety process, the role of the safety engineer in the Design/Build Team structure, and how he influences the final design of the product. In addition, the paper describes how the Computer Aided Three -^sDimensional Interactive Application (CATIA) software design tool is utilized by the system safety engineers to ensure that human performance, the burden design imposes on manning concepts, personnel physical skills, training requirements, safety and health hazards induced by systems, was considered throughout system design and development.
