The study covers wide-ranging topsides payloads from 18,000 tonnes to as much as 36,000 tonnes for the incorporation of a self-contained platform rig.
The scenarios also indicate that production capacity is anticipated to be well above 100,000 barrels per day of oil.
Aker Kvaerner is participating in the engineering analysis of a deep-draft semi-submersible while Technip is involved in similar work for the spar hull.
