English Maritime Terminology on Naval Engineering

Marine ventilation systems are of great importance. The purpose of high-quality marine ventilation is twofold: it contributes to maintenance of a vessel by reducing the growth of mold and removing musty air and it benefits the comfort level onboard as well. Marine ventilation is a necessity for the performance of engines and other equipment. Ventilation systems both move the air and equalize humidity levels inside and outside the boat. In broader terms, ventilation is understood to be all the steps taken to prevent damage to cargoes from condensed moisture within the cargo holds. One such option for preventing condensation within a cargo hold is the method of air conditioning of the cargo hold atmosphere by the use of a dehumidifier in an internal circulation mode, which does not fit in the narrow definition of ventilation. The primary purposes of ventilation are to minimize damage to the cargo and to ensure the safety of the crew and vessel. This is achieved by minimizing the formation of sweat by dew point control, removing hazardous gases which may be emitted by the cargo, preventing excessive heating of the cargo, and removing taint.
