Abstract: The invention concerns a ship's door or ship's frame arrangement which is provided with a door frame and a removable door leaf mounted in it. Peripherally mounted on one of the mutually facing peripheral edges of the frame and the door leaf and serving as a dynamic seal is an elastic tube which is connected to a pressure medium source and which, when pressurized, presses between the peripheral edges of the frame and the door leaf, thereby forming a seal between them and, when depressurized, lifts away from the opposite peripheral edges to form an annular clearance. In addition to the dynamic seal, a peripheral static seal is provided which serves as a spray-guard.
