  • 10,000 PSIG design pressure
  • 3 piggable flowline boarding stations
  • 2 new flowline heaters
  • Riser base gas lift
  • Structural deck extensions & access platforms
  • Production manifold skids
  • Additional HPU & chemical injection
  • Piping modifications necessary to tie in the new facilities
  • Designed to USCG & BSEE regulations

Scope of Work:

  • Topsides engineering & design
  • Regulatory interface & compliance (DNV & BSEE)
  • Automation & integration of topsides equipment
  • Procurement of all topsides equipment
  • Hull & subsea well interface
  • Topsides weight control
