Abstract

An investigation of the recent advancements in modelling and optimisation techniques to develop maintenance strategies for offshore floating systems have been carried out in this paper and identified that the impact of time required to carry out activities have not been considered as an influencing factor in any of the existing formulations reviewed. The influence of time required to complete the activity, on the prioritisation of activities have been demonstrated in this work by means of a novel optimisation problem formulation for Floating Production Storage and Offloading Facility (FPSO) that maximises maintenance personnel resource utilisation and enables FPSO condition enhancement. To find the Pareto-optimal solution, an overall objective function has been developed considering the priorities with respect to design features, operating conditions, deteriorations, and the consequences of not doing the maintenance, taking into consideration the personnel resource time required for activity completion. This formulation provides flexibility to direct the focus of the overall objective function towards any one or more of the objective functions by adjusting their respective weight according to the maintenance strategy followed, which would supplement Regulatory oversight requirements of the FPSO.
