A measurement session is a part of a measurement campaign that contains thickness measurements executed in a single location (port stay, on voyage or dry dock) by specified personnel of a thickness measurement company, supervised by a surveyor within a contiguous period in time. This period can be for example as small as a working day. A measurement campaign may consist several measurement sessions due to limitations in time and accessibility of structures and compartments, the vessels schedule or limited dry dock capacities. Measurement sessions will differ by time frame, location and/or executing company. 
Each measurement point with value must be associated to exactly one measurement session. If there is only one session, this association can be implicit.
