This program is for the steady-Mate analysis of single- 

 point mouring systems with a surface buoy under the 

 action of a unidirectional curienl and coplanar windy 

 The program includes the cffci ti of normal and tungc^- 

 tial drag, discrete elements along the cable, and cable 

 extension. Solution begins bv ^issuniing an angle of 

 inclination for the cable at the buoy and fits the cable 

 to the water depth using an iter.itivc process with wind 

 and current drag forces as input. A program dcscriptirn 

 and listing arc given in Reference 40. 



This program is for the steady-state behavior of single- 

 point mooring systems under the action of wave and 

 current forces. The progr^tm is liascd on a lumped mass 

 model of the cable and elemental packages and uses a 

 Continuous System Model Program (CSMP) which allows 

 analog-like simulation with a digital computer. The pro- 

 gram docs not require sophisticated integration routines 

 because integrators arc built into the CSMI" system; 

 however, computer time can be quite high. A listing of 

 the program can be obtained from the author. 



This program (No. H21032) is for the steady-state analysis 

 of a single-point, moored, submerged, cylindrical "buoy" 

 under the action of a current that may var>' in magnitude . 

 with depth. The cable is assumed to be semirigid and to 

 be made up of a straight section of cable at the bottom 

 and a section approximated by a circular arc at tlic top. 

 Solution for cable shape and tension and buoy inclina- 

 tion is by integration of the differential equations of 

 cable cquilibri jm. A description of the program without 

 a listing is given in Reference 42. 



This program is for the steady-state analysis of single- 

 point mooring systems in a unidirectional current. The 

 program solves the equations of static equilibrium for the 

 cable by Kunge-Kutta integration. Both normal and 

 tangential drag are considered. The program is considered 

 proprietary^ therefore, some details are not known. No 

 listing Is available. 



This program uses analog simulation to solve the vet of 

 second-order partial differential equations associated 

 with single-point mooring systems under the action of 

 wind and current forces that are unidirectional and 

 coplanar. The cable is simulated by up to 10 straight
