Watertight air dampers for ships are primarily employed in the ventilation systems of various vessels and offshore oil platforms, typically installed on ventilation ducts within watertight bulkheads below the waterline. Should a bulkhead breach occur, sealing air dampers must be closed to prevent water ingress propagating through ventilation ducts to adjacent compartments. This watertight barrier is indispensable for ensuring the safety of vessels and offshore oil platforms.
