Abstract: The objective of this paper is to study different analysis methodologies for the design of floating production systems. The main issues are the use of uncoupled and coupled analysis methods, and the integration in the analysis and design of the mooring system and the risers. This paper is a companion to another paper also presented in the OMAE2002 Conference [1] The present paper begins describing a “basic” classic, uncoupled methodology, and proceeds with comments on some refinements in the representation of … Show more

“…It is important to distinguish between these two aspects, because, as shown in Ref. [10], some level of integration between mooring lines and risers can be achieved even when only uncoupled programs are available, comprising refinements on that "classic" uncoupled methodology. Such refinements, which have been available for the last 20e30 years or so, consist for instance in employing enhanced procedures for the determination of the scalar coefficients introduced in the vessel equations of motion to represent the behaviour of the lines; for more details please refer to Ref.…”

“…As has been discussed in Ref. [10], two main aspects can characterize a so-called basic or "classic" uncoupled methodology: a) The use of numerical analysis tools based on uncoupled formulations, where the hydrodynamic behaviour of the vessel is not influenced by the nonlinear dynamic behaviour of the lines; b) The consideration, in the analysis procedures, of few or no integration between the moored system and the risers. It is important to distinguish between these two aspects, because, as shown in Ref.…”

“…Recently, researchers have been acknowledging that the design of FPS should consider the fact that the moored system and the risers comprise a truly integrated system, that is, the overall behaviour of a floating system is dictated not only by the hydrodynamic behaviour of the hull, but also by its interaction with the hydrodynamic/structural behaviour of the lines [1][2][3][4][5][6][7][8][9][10]. Throughout the last decade, Petrobras (the Brazilian state oil company) have recognized this need of formulating and developing a computational system for the coupled numerical simulation of FPS.…”
