About

Ventilation, in its most basic form, is the supply of fresh air into a space. On bulk carriers, this generally means the provision of fresh air into the cargo holds, which is achieved through either natural or mechanical means. 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 cargohold 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.A natural ventilation system, as the name suggests, is based on nature’s law of air circulation. Air can enter and leave the hold through the vents located above the deck level. This allows cool, heavier air from the outside atmosphere to replace the lighter, rising warm air inside the cargo hold. Some older designs of dry cargo ships were fitted with ventilator shafts leading to the lower parts of the cargo hold. In these cases, air circulation in the cargo hold was achieved by trimming the ventilators (cowldirection) with respect to the wind direction. This was more effective on general cargo ships carrying bagged or breakbulk cargoes requiring through ventilation. Through ventilation is when the air is forced into the body of the cargo. It is generally not required for solid bulk cargoes and is difficult to achieve. When a hold is loaded with a solid bulk cargo, the ventilation provided is usually surface ventilation, with air flowing over the surface of the cargo from ventilators. On newer designs of dry cargo ships (particularly bulk carriers), the hinged-door type ventilators are often fitted on the sides of the hatch cover. These can then be opened depending on the relative wind direction to provide adequate surface ventilation within the cargo hold.
