The financial resilience of a Floating Production, Storage and Offloading (FPSO) plant is investigated through a hybrid modeling approach. With linked sub-models for economics, reliability and process safety, simulation results of the underlying transient nonlinear phenomena are shown, which represent the complex behavior of operation of the FPSO. The economics model is based on the Norwegian tax system with net cash flow as the main quantity. In the reliability model, statistical methods are used to obtain probability density functions for individual topside and subsea components. The safety model is centered around EHS 1 1 Environment, health, safety. time, in which a sufficiently high skill level is aimed to be maintained. Ample emphasis is given to parsimonious modeling, in which various engineering concepts are used in a way which avoids visual pollution. It is concluded that organizations that operate FPSO plants (under Arctic conditions) are not financially resilient per se , other than through a previously accumulated cushion of cash, which can rapidly deplete due to insufficient maintenance and repair of equipment, and even more so in case of major or frequent accidents. A (much) more conservative revenue stream should therefore be assumed as ground truth when considering exploration and exploitation of petroleum reservoirs in sensible (deep sea) ecosystems, as these are characterized by low natural resilience and also low potential for recovery. This work provides a set of analytical tools for technical managers, re-insurers and system engineers from the petroleum industry, which give a quantitative and more holistic perspective on the financial risks involved in such projects. The outlined general methodology, domain-driven design for implementation, and complete model description allow to rebuild applications for other contexts. • Case study using System Dynamics with heavy use of field data. • FPSO operation based on Norwegian economy and Arctic conditions. • Inter-/trans-disciplinary approach covering economics, technology, and safety. • Tutorial style and complete description of models and methods. • Introduction of financial resilience.
