Results of an evaluation clearly show that deepwater technology development for benign environments has limited use in the hostile waters of the Atlantic margin. For such environments, developers need experience with current harsh environment technology. This is more important than experience in ultradeep benign environments. BP PLC and Statoil ASA reached these conclusions after evaluating the maturity and applicability of concepts for deepwater harsh-environment oil production. The evaluation included six different floating concepts, together with 13 riser systems. The two-step ranking process involved: 1. A systematic review of each concept against a number of criteria. 2. Ranking of each criterion using a colored traffic-light system. The study used 30 criteria, divided into six categories, such as HSE (health, safety, and environment), technical maturity, technical flexibility, construction cost, installation cost, schedule risk. The study also established a matrix showing which riser systems are compatible with the different floating systems, based on the combined technical knowledge of BP and Statoil experts on floater and riser concepts.
