Octoplus: a new FPSO concept
William HUDSON, DORIS Engineering
The OCTOPLUS is an improvement on the classic FPSO, which has gained a reputation for budget and schedule over-runs. The base case is designed to store 2 200 000 barrels of crude oil, produce 250 000 barrels of oil per day and be installed in deep water in Brazil. The concept can be adapted to a wide range of configurations of storage, production, water depth and metocean conditions.
On a like-for like basis it is expected to offer a 20 to 30% cost reduction with respect to a classic FPSO. The principal advantages of the OCTOPLUS over alternative concepts are:
-.Topsides and deck installation is independent of the hull
- Hull can be built in a shipyard
- Exceptionally good hydrodynamic behaviour
- Improved oil storage system using the proven oil/water displacement system
- High level of Safety and separation of zones of risk
- Reduced lead time for phased developments
- Structural efficiency
The above characteristics and advantages make the OCTOPLUS concept a significant improvement over existing FPSO designs and particularly suitable for future deepwater developments.
