          成功案例: 石油天然气

          Anonymous (France)

          成功案例: 石油天然气 Availability better than 99,977%, Overall target unreliability < 1 occurrence/year

           

          I. CUSTOMER ENVIRONMENT / PROJECT CONTEXT

           

          Customer profile:

          • Consulting Engineering for all fields relating to Natural Gas. In partnership with foreign companies, it was responsible for the new liquid natural gas terminal designed to provide 8 billions m3 of Natural Gas per year with a storage capacity of 330,000 m3 in 3 reservoirs.
           

          Customer objective and constraints:

          • Validate the electrical distribution network architecture to show that availability and reliability targets for the process have been met, taking into account:
             - Load sensitivity
             - Futur network expansion
             - Equipment maintainability
           

          II. SOLUTION IMPLEMENTATION

           

          Implementation methodology (main phases):

          • Electrical Distribution Network Reliability Study
            1. Understand and identify risks
            2. Optimize architecture, compare solutions, highlight weak points
            3. Design redundancies and back-up configurations
            4. Optimize maintenance plan
           

          Duration:

          • 2005: 6 months

          III. RESULTS / ACHIEVEMENT

           

          Customer benefits:

          • Loss of gas emission on distribution & transport network :
             - Overall target unavailability < 2 hours per year; P(t) < 2,28.10-4; Availability better than 99,977%
             - Overall target unreliability < 1 occurrence per year; λeq (t) < 1,14.10-4 /h
           

          Schneider Electric differentiating values VS competitors:

          Target availability and reliability are achieved thanks to:
          • Taking into account dependability issues from the early stage of the project
          • Redundancy implemented at architecture level
          • Automatic reconfiguration
          • Process equipment dispatching
          • Failure detection system
