Innovative floating structures, such as a Spar, FPSO (Floating Production Storage and Offloading), and semi-submersible are attractive concepts for an ultra deep water production platform. In this research, a Classical Spar platform has been considered as a theme floating structure for the simulations of interactions with a polyester mooring system.

Because the properties of synthetic ropes are very unique, very little knowledge is available for the design of synthetic mooring lines. In this study, we developed a method to use an empirical formula (Del Vecchio, 1992) to model the modulus of a polyester rope based on its mean and dynamic loads and then used it to simulate dynamic interaction between a classical SPAR and a hybrid polyester mooring system in the time domain. The statistics of motions of the hull and tension in the mooring lines are compared with those related to a conventional steel chain mooring system.
