Indonesian oil patch is full of marginal oil fields which if developed will help to boost the economy of the continent tremendously. Such marginal field is uneconomic tobe developed using current technologiesbased on the existing production facilities. This research proposed a methodology to optimize FSO principal dimension based on motion criteria subject to defined platform and metocean at a specified location. Parametric study involving 72 main dimensions variation had been carried out for various L/B and B/D ratios. Such main dimension variations were derived based on the existing FSO operated in Java Sea. Numerical simulations have been conducted using Hydrostar to investigate motion responses in both regular and irregular waves. The results obtained from the investigation indicated that heave, roll and pitch motions were influenced by L/B and B/D ratios. It is concluded that the design methodology to suit specific metocean conditions is an effective approach to minimise motion behaviours.
