Flexcom provides the option to view the response of the vessel in the Vessel Response Plot. The response can be shown for any of the local Vessel Degrees of Freedom, depending on the option selected in the Plot drop-down list. By default, the response is presented at the vessel reference point, but any arbitrary point on the vessel (e.g. riser hang-off location, tip of crane arm) may also be selected.
If you are interested in examining the vessel response at some location other than the vessel reference point, you can explicitly specify an alternate location via the X Offset, Y Offset and Z Offset inputs in the Vessel Response Plot. These offsets are relative terms defined with respect to the vessel reference point, and are specified in the local vessel XYZ axis system.
Note that the Vessel Response Plot operates in a synchronised manner with the relevant input data. For example, when any data pertaining to vessel RAOs or wave loading is altered in the keyword file, the plot updates automatically.
A vessel may be defined using either one of two keywords, *VESSEL or *VESSEL,INTEGRATED. While the former is perfectly valid, it has effectively been superseded by the latter, which is now the recommended option. *VESSEL,INTEGRATED is a more comprehensive keyword and has several advantages over its predecessor. Most importantly it accepts RAO data also, thereby eliminating the need for a separate *RAO keyword – hence the ‘integrated’ nature of the new keyword. Further details are available in Basic Vessel Concepts.
The Vessel Response Plot operates like all other plots in Flexcom. For further information refer to Plotting.
