The participants displayed a spirit of cooperation that led to the 

 success of the meeting. 



Format 



The two-day seminar was organized into three sessions. Session I 

 covered the first day and consisted of short presentations by each 

 attendee summarizing the problems associated with his particular area of 

 expertise. Guidelines as to subject matter for these presentations were 

 outlined in advance by CEL to insure complete coverage of the disciplines 

 associated with mooring analyses. A short discussion/ question period 

 followed each presentation. 



Session II was held on the second morning and was the most important 

 part of the seminar. Session II was an informal discussion which allowed 

 the participants to build on the presentations of the first day. The 

 intent of Session I was to brief each participant on the problems and 

 limitations within each discipline (vessel motion, cable dynamics, 

 etc.), while Session II was an opportunity for a free exchange of questions 

 and ideas aimed at evaluating and extending the state-of-the-art in 

 mooring analysis. 



Session III was held at the end of the second day and started with 

 a description of the Navy's mooring needs as seen by CEL. The intent of 

 Session III was to get specific recommendations from the attendees 

 regarding the development of a mooring analysis capability. This dis- 

 cussion was purposely placed last to avoid any bias in the Session II 

 discussions on mooring models in general. 



Session I 



The seminar attendees were carefully chosen to represent all the 

 "building blocks" necessary to evaluate and assemble mooring models. 

 The presentations on the first day were divided into two groups: mooring 

 system behavior and mooring system excitation and analysis. The following 

 presentations were made during Session I: 



Mooring System Behavior 



• Mooring Dynamics Models Dr. B. J. Muga 



• Mooring Cable Dynamics Dr. R. L. Webster 



• Diffraction Theory, Including 



Mean Drift Forces Dr. C. J. Garrison 



• Vessel Equations of Motion Dr. R. Bhattacharyya
