Subject to drydocking. This would possibly be used by a charterer in the negotiations for a time charter in order to establish that a ship would be allowed to be dry docked by the owner but would be off hire during the ducking period.
Subject to licence being granted. This term is used in negotiations as regards the chartering of a vessel at a time when owners are not free to commit their vessel for a certain employment without having obtained the approval of competent authorities. Consequently, a charterparty issued under such condition is not effective until such licence has been definitely granted.
