Unplanned Maintenance Period is to be understood as a period during which the vessel is immobilized in
order to maintain or repair (in case of breakdown), a major equipment (critical equipment or show stopper as
per definition given in section 4.7 and 4.8), whatever if the vessel is under charter or not. Thus, this period
ends once maintenance or repair is completed, and after test and sea trials as applicable.
