Presents a reational method for analyzing, designing or evaluating mooring systems used with floating units. This method provides a uniform analysis tool which, when combined with an understanding of the environment at a particular location, the characteristics of the unit being moored, and other factors, can be used to determine the adequacy and saftey of the mooring system. Some design guidelines for dynamic positioning systems are also included. Appendix K of 2SK replaces recommended practice 95F.
