- Abstract
- Breaking of mooring lines is a topic that must be analyzed during the design process of a floating production system. In current design codes this subject is treated as an accidental case. Nevertheless, transient effects after breaking of a line are not considered as relevant. In this paper an analysis of the relevance of the transient effects, in taut-leg mooring line systems made of chain-polyester-chain in an FPSO with ultra-deep depth under severe storm conditions, is considered. Several coupled analysis in time domain in two ways were performed: 1) When a mooring line is absent since the beginning of simulation (with no transient effects); 2) Breaking a line during simulation (with transient effects).
