Numerical Studies on the Effects of Mooring Configuration and line Diameter on the Restoring Behaviour of a Turret- Moored FPSO

“…Niedzwiecki and Casarella [20] presented one of the earliest contributions in the form of a computational algorithm for solving dimensionless catenary equations of the mooring line. A variant approach for the determination of tension-displacement of a slack mooring line was also presented in [21]. Similarly, a case of a single-point mooring system with uniform cable was studied by Nath and Felix [22] to predict mooring line motion and tensions resulting from oscillating wave forces.…”

Analysis of FPSO station keeping characteristics

“…Ansari 1980 conducted an extensive study of mooring systems with a multi-component mooring line system. The study presented a broad description of the various mooring lines usually available for use and presented an analysis tool in determining the effect of line stretch and the stiffness characteristics of a multi-component line system [7]. In 1991 he also presented a study on the design of multicomponent cable systems for a moored offshore vessel.…”

“…Vargas et, al, performed a study on the stress concentration factors for stud-less mooring rope links in the fairleads. The study analyzed the stress concentration factors on seven (7) pocket fairleads, showing a maximum stress concentration less than 1.20, [14]. Ridge et, al, in 2006 conducted a study to predict methodologically the torsional response in large mooring systems.…”
