Dynamic analysis of FPSO with a tandem offloading system
- Univ. of Sao Paulo (Brazil). Dept. of Naval Architecture and Ocean Engineering
Turret-moored tankers have been conceived by the oil industry as a Floating Production Storage and Offloading system (FPSO). The oil stored in ship hull may be offloaded by a shuttle ship connected to the FPSO by a hawser, in a so called tandem system configuration. The problem of dynamic instability, that arises with other ship mooring systems, like single point mooring and spread mooring systems subjected to the environment forces, may also be present with the tandem system. The present paper is concerned with the dynamic analysis of the tandem system. It is an extension of the research that the authors had carried out with the application of a new mathematical model to deal with the SPM dynamics. This formulation is a manoeuvering model specially developed to represent low speed ship motion. Initially presented is the mathematical model that represents the dynamics of the tandem system. Particular emphasis is given to the description of the slow ship dynamics for the two vessels. Simulation of the mathematical model is used to analyze the dynamical behavior of the tandem system. The effects of hawser length, wind and current speeds and wave angle of incidence are investigated.
