Here you can add/edit/delete ROVs.
ROVs are useful for simultaneous operations in IC-Inspection: whenever you have (or might have) two ROVs in the water at once (or more generally two separate sources of video at once, even if one or more of those sources is not actually a ROV), you should add a ROV for each source. (A single multi-channel source, such as several cameras on one ROV should be represented by just one ROV.)
Each ROV can be associated with one or more Survey Sets, which are in turn associated with events.
Then, when NEXUS IC plays back video for review, it can play the correct channel(s) of video for that event. Similarly the Pipeline View chart can show correct data.
