DYNAMICS OF DEEP-SEA MOORING LINES
1968
Reid, Robert O.
Equations of motion for the three-dimensional aspects of mooring line dynamics are formulated and dealt with in a coordinate system which facilitates analysis of the transverse and longitudinal modes of motion. A visco-elastic model for the mooring line material is adopted which allows for hysteresis effects and non-linear load-strain processes. A numerical procedure for solution based upon the method of characteristics is discussed in some detail. The linearized equations for three-dimensional small perturbations relative to a coplanar equilibrium configuration are formulated and applied to the problem in which the motion is stipulated in a stochastic sense at the upper end of the line. More general conditions at the upper end are discussed but not applied.
