Yadana – MCP Platform



DORIS performed the FEED, the Call For Tender and early Detailed Engineering for the MCP platform of Yadana.

Project outline

  • Topsides: 2 Modules over Module Support Frame (MSF)
  • Substructure: 4 Legs Jacket / 4 driven Piles
  • MCP platform weight : 7500 t
  • Bridge linked to existing Production Platform( PP)
  • Provision for future LCP (Low Pressure Compression)
  • 2 Turbo-Compression Trains (one per Module) with dedicated scrubbers & aero-coolers, fed from fuel gas.
  • Technical Rooms (Electrical, Instrumental, HVAC, workshop)
  • Other Main Equipment: Emergency Diesel Generator, Electro-hydraulic Pedestal Crane, Fuel Gas Package, Air Compressor Package, Nitrogen Package.

The MP Compression Platform (MCP) is connected by bridge to the existing Production Platform (PP) and to the future LCP Platform. The objective of MCP is to maintain the Gas Sales Production whileWellhead Flowing Pressure reduces (reservoir specificity).
