Note that multiple states of a catenary line can be computed and displayed in one operation.

1. 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. Running on any Microsoft Windows (32bit) PC, WinCAT brings sophisticated and complex catenary analysis to the desktop of any offshore practitioner who needs to get the job done fast.

2. WinCAT handles catenary calculations for many problems, from the simplest single chain or wire moorings to complex composite moorings with buoys and wire/chain combinations. 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.

3. WinCAT works with multiple catenary lines, and the plots can be simultaneously displayed for comparison of 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.

4. WinCAT makes the setting up and managing of catenary data extremely easy, even for someone unfamiliar with cable systems. A data creation wizard guides users through the simple data entry forms which have plenty of help tips and present sensible default data wherever possible.

5. Lines are defined from the vessel end working towards the anchor. A line may have one or more sections, each having a length of line ending at a node (which might be a join to the next section, a buoy, or the anchor for example). Algorithmic line Types (ALTs) are a set of types for which only the line size need be given and the other properties are automatically computed. (ALTs are an upgrade option). WinCAT has some special line types already built-in. The first of these is the default “Unspecified” which allows free input of all properties.

6. Once entered in the database, the properties are automatically copied as data for a particular catenary line just by selecting the required type name from the drop-down lists of the input form. A unique and powerful feature of WinCAT is the Database where the user can set up and manage the properties data for commonly used lines. The database is stored with the WinCAT data file so project or vessel specific data sets are always available when working with the data file.

7. There are three in-built units sets covering the most commonly used metric and imperial systems. However, users can easily create and use their own units sets through the powerful database capabilities. Work in any units you like with WinCAT. Data can even be entered in a different set of units to that chosen for display of results.

8. Note that multiple states of a catenary line can be computed and displayed in one operation. WinCAT is truly 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.

9. The numeric results table shows all the desired output from the computations in an easily understood format. The results table can be included in the printed output.

10. The content and order of the results table can be customised so that only the information relevant to the particular analysis is presented.

11. The WinCAT catenary plots are accurately drawn and can be resized, zoomed, and modified interactively to show all the information that may be needed.

12. Roaming the cursor within the plot window provides an immediate feedback of information on line properties and co-ordinate positions via the status bar display. Spot selection of particular line elements brings up a detailed information box.

13. Cursor functions extend to the accurate measurement of distances and angles. A measure result box pops up immediately a line is dragged anywhere in the plot window.

14. 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.

15. Easy to use, accurate and reliable in operation, WinCAT is ready to perform both onshore and offshore in design analysis, installation studies, anchor laying, rig moves, sub-sea operations and many, many more applications. WinCAT is a new generation analysis tool designed to put capability into the hands of those responsible for making planning and operational decisions as well as engineers, designers and specialists.
