Success Story: Oil & Gas

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

Solution overview (services, products, systems, architectures...):

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:

• 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
