Success Story: Oil & Gas

I. CUSTOMER ENVIRONMENT / PROJECT CONTEXT

Customer profile:

• The biggest Transport & Storage company in Russia
  
• Controls most of the Russian oil pipelines
  
• Big user of Modicon PLCs
  
• System integrator: Neftevavtomatika

• The Grushovaya oil transfer tank farm is one of Transneft's biggest sites in Russia.
  
• This tank farm is used as a buffer to collect oil from several pipelines.
  
• It includes: Underground reservoirs and reservoirs with floating cover. Technological and inter-tank pumping stations. A flow and pressure control unit. A diagnostic pig launch and reception unit. Wells equipped with slide valves. Technological tunnels. Loading-unloading dock
  

Customer objective and constraints:

• Replace the obsolete relay-based system
  
• Increase system flexibility
  
• Prepare system to handle the increased throughput of the technology
  
• Reduce installation and commissioning costs
• Enhance communication networks and bring them to the corporate standard – Ethernet-based network
  
• Speed up the fault diagnostic process
  
• Preserve the existing instrumentation base

II. SOLUTION IMPLEMENTATION

Implementation methodology (main phases):

• The distributed control system of the GRUSHOVAYA tank farm is unique in terms of the project size that involved Industrial Ethernet technologies, implemented by Schneider Electric System integrator Neftevavtomatika in Russia and the countries of the CIS.

Duration:

• 2004
