DORIS delivered FEED and early detailed of 25,000 ton Topsides, 20,600 ton Jacket and FEED of pipelines network.

Project outline

The Shwe development consists of a Drilling and Central Production Platform, single platform installation by float-over concept. Mya field was developed from two subsea drilling centres, Mya North in 196 m of water depth and future Mya South in 600 m of water depth. Gas is transported via infield pipelines to the Shwe Platform and via an export pipeline from this platform to landfall at Kyaukphyu and the terminal on Ramree Island.

  • Water depth: 110 m
  • 2 train gas treatment 640 MMscfd + 1 future train 320 MMscfd
  • Dew pointing offshore
  • Turbo compression 3x 50% ; duty 10.5 MW
  • MEG injection for JT Process and Subsea
  • Topsides weight 24 500 t dry gross
  • Floatover installation
  • Jacket weight 20 600 t
  • 16 piles 108’’ 110 m penetration
  • Production Capacity: 960 MMscfd
  • Export Pipeline: 32” x 110 km
  • Infield Pipeline: 14” x 12.5 km
