How to determine the principal dimensions of FPSO vessel

The evaluation of the principal dimensions of the Floating Production, Storage and Offloading (FPSO) system is one of the most critical tasks at the initial design stage of the vessel. It is therefore important to get this right from the onset. This paper presents a simple method of determining the optimal principal dimensions of FPSO vessels of any specified oil storage capacity. An interactive programme, the Principal Dimensions Programme (PDP) has therefore been designed to accurately evaluate them based on the required cubic number (L× B × D) and the needed oil storage capacity (as the modern segregated vessels are volume-limited). The prediction of these dimensions has been given to ensure a safe operation and optimal performance of the vessels with regards to their motion responses in deep sea waves
