The primary purpose of my PHD project is to develop novel tools for decision-making processes related to MPOP infrastructure planning and including location and system selection by applying risk-based techniques. The literature review has identified significant gaps in the existing knowledge regarding designing and operating multi-purpose offshore platforms (MPOPs) based on Australia’s offshore environmental data. Despite the growing interest in offshore co-located systems, there is a lack of knowledge about the available resources, combination requirements, and operation and maintenance (O&M) activities. In addition, there is an urgent need for decision-making frameworks that account for the consequences and risks associated with co-locating offshore facilities, especially in MPOP design and operation planning.

The previous research highlighted the need for further investigation and innovation in developing MPOPs, particularly in the Australian context, to ensure their effectiveness, reliability and sustainability while protecting marine ecosystems. This project aims to address the identified research gaps and enhance the understanding of MPOPs by developing methodologies and frameworks for resource assessment, systems integration, probabilistic failure analysis, risk assessment and decision-making.

The first objective of this project is to create a method for the assessment for MPOPs motion responses and damage propagation based on metocean data collected from potential sites. This will involve analysing various factors, such as wind, wave, and current data, to determine the likelihood of structural damage in potential locations for MPOPs. The second objective is to develop a quantitative risk profile for MPOPs design and operation, considering several criteria like critical technical, environmental, and cost. Finally, the project will develop a risk-based decision-making framework for systems integration and site selection of MPOPs. This framework will be based on a thorough risk analysis, including potential failures and their consequences, to enable effective decision-making regarding the design of MPOPs. The project outcome would be highly beneficial for both the offshore and aquaculture industries, serving as a powerful tool for increasing the overall efficiency and reliability of multi-purpose offshore platforms during their entire life cycle.
