Right now a field study has a vessel and the vessel is used by the field study.
But what if it's not a vessel but something else? Should we be representing platforms and deployments? A Vessel is a subclass of a Platform. And a Platform is deployed during a time period with certain conditions. A vessel can be deployed multiple times in one field study, and deployed in other field studies with different conditions.
