Green rig
Deepsea Stavanger is designed for environmental sensitive areas, and the utmost focus has been put on zero discharge  low emissions and electrical solutions to reduce onboard oil volumes and associated pollution risks.
Separate drain systems are installed for the machinery area, drilling area and all outside clean deck areas. No drain water is discharged without passing a cleaning system which ensures acceptable oil content.

Installations and arrangements to obtain green rig:
  • Enclosed derrick which prevents mud spill to sea
  • All drain lines routed to central cleaning unit by use of several tanks and pumps
  • Discharge from mud pits by pumping, no gravity discharge
  • Waste management system implemented
  • Low emission of NOX, clean design engines
  • Closed loop BOP control system
  • Electrical drawworks with power regeneration
