Card #8 



Note: 



DAMP(l) = Added damping in sway. In the equations of 



motion sway damping will be 1+DAMP(1) times the 

 computed hydrodynamic damping. 

 DAMP (2) = Added damping in heave. 

 DAMP (3) = Added damping in roll. 



NPUNCH = 0, punch data cards containing computed trans- 

 mission coefficient, motion response and mooring- 

 force coefficient. 

 = Anything else, do not punch data cards. 

 Mooring spring constants. Format (9F8.3). 

 This is read in subroutine DYNAMC. 



Card #9 



RKM0R(1,1) 



= KMii- 



RKM0R(1,2) 



= KMi2. 



RKM0R(1,3) 



= KMi3. 



RKM0R(2,1) 



= KM21. 



RKMOR(2,2) 



= KM22. 



RKM0R(2,3) 



= KM23. 



RKM0R(3,1) 



= KM31. 



RKM0R(3,2) 



= KM32. 



R1CM0R(3,3) 



= KM33. 



Mooring-line response parameters, Format (6F10.2). 



This card is read in subroutine MORTEN. 



DELT(1,1) = AF/Aa for shoreward mooring line. This is 



the change in mooring line force per unit 



displacement in sway. 

 DELT(1,2) = AF/Aa2 for shoreware mooring line. 

 DELT(1,3) = AF/Aa^ for seaward mooring line. 

 DELT(2,1) = AF/Aaj for seaward mooring line 

 DELT(2,2) = AF/Aa2 for seaward mooring line. 

 DELT(2,3) = AF/Aa^ for seaward mooring line. 

 The last 3 cards (#7, #8, and #9) provide the information 

 needed for the dynamic analysis. If it is desirable to 

 perform calculations varying the data, these cards may be 

 repeated with different input data. There is a limit of 

 25 different sets of data. In the example data shown in 

 Table D-1, there are 3 different conditions used. 



5. Mathematical Procedures and Program Limitations . 



The mathematics has been described in the report and Appendix C. 



The main limitations are that at most 23 offset points may be used 

 to describe the shape. This has been found to be very adequate for the 

 configurations considered thus far. Little change in the results occurs 

 when more than 15 points are used. Computer time increases about as 

 the square of the number of points . 



A listing of the program is given in Table D-2. 



6. Flow Chart . 



A flow chart is given in a figure of this appendix.
