            Fos Cavaou LNG Terminal (France)

            MV architecture dependability design for O&G large sites

            Reference: Oil & Gas Availability better than 99,977%, Overall target unreliability < 1 occurrence/year
            Availability better than 99,977%, Overall target unreliability < 1 occurrence/year




            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 billion 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
               - Future network expansion
               - Equipment maintainability



            Implementation methodology (main phases):

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

            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
