The paper identifies the advantages, features and applicability of a concrete hull for an FPSO and the issues related to project execution. For those considering the options for other field developments, the paper identifies the conclusions and the work on which these were based. The content of the paper is based on extended studies on the advantages, design features and feasibility of fabrication of this new design of FPSO hull. This work formed part of BP`s review of options for the development of their Schiehallion field in 375 meters water depth West of Shetland, the Atlantic Frontier. The conceptual design of vessel hull was carried out with the objective of providing the best solution for a concrete FPSO for BP`s application. This included consideration of capital cost, system availability, operating costs, HSE aspects, decommissioning and disposal. The flexibility of the concept e.g. for addition and modification during service were also examined. The design process was taken to the stage where these matters had been examined and the design has approval in principal for certification. During the design process the mathematical modeling of vessel motions and mooring forces were confirmed in tank tests. BP participated in the proof of concept, retaining the concept on their final short list of two options for the field development. It was concluded by all parties that this new concept had been fully examined and proven technically.
