摘要

This work investigates steel catenary risers applied to FPSO's (Floating Production, Storage and Offloading units), by analyzing alternative configurations for the SCR's with and without floating elements, and considering different positions of the turret in the FPSO. The behavior of these configurations is simulated by numerical models, by using nonlinear time-domain dynamic analyses methods. The results are assessed in terms of maximum stresses corresponding to extreme environmental loadings, and fatigue life. The results of the analyses provide information to determine the configuration that better fits the conditions imposed to risers connected to FPSO's.
