11. WinCAT User Manual Creative Technical Solutions Page 2 INTRODUCTION ABOUT WINCAT WinCAT is PC Windows software for the analysis of hanging cable systems such as offshore moorings umbilicals and flexible risers WinCAT is very powerful but is also easy to use WinCAT has an optional Workboat capability that allows a surface craft to be introduced into the cable system This allows analysis of anchor running cable laying and many other offshore operations involving mooring lines umbilical cables bundle towage etc Output results are presented as graphic plots of the catenary line together with a comprehensive table of numeric results These can be printed and also output to other Windows software eg Excel for further manipulation WinCAT works with multiple catenary lines and the plots can be simultaneously displayed for comparison of results Also multiple states of a catenary line can be computed and displayed in one operation WinCAT is interactive the catenary setup can be readily modified through the on screen forms and the effect is immediately computed and reflected in the tabular and plotted results The data for all catenary lines is saved to the same data file so that all analysis scenarios for one project or one vessel can be held in a single dataset WinCAT makes the setting up and managing of catenary data extremely easy even for someone unfamiliar with cable systems Check out the powerful capability featur
