Just like land-based vehicles such as truck bodies, cargo vans, and trailers, marine vessels require proper ventilation to ensure the health, safety, and comfort of occupants, the longevity of equipment, and the avoidance of degradation of certain cargo.
Here is a brief look at the critical role proper ventilation systems play in marine vessels.
For starters, ventilation systems provide fresh air and maintain an appropriate temperature for crew and passengers on board. They also reduce the levels of carbon dioxide and other contaminants.
Preventing the spoilage of perishable goods on board is also important. Proper ventilation controls temperature and humidity levels to avoid spoilage and loss of cargo value. As important as that may be, it may be one of the less significant roles of proper ventilation on a marine vessel. Consider the transport of hazardous materials. Adequate ventilation is essential to prevent the accumulation of dangerous fumes and gases and to ensure the ship and its crew remain safe.
The cargo hold isn’t the only place hazardous gases exist on a boat or ship. Toxic gases like carbon monoxide and sulfur dioxide also emanate from machinery spaces and fuel compartments. Proper ventilation is critical to expel these poisonous fumes, prevent their accumulation, and reduce the risk of explosions and fire from flammable gases.
Reducing the temperature in machinery spaces prevents equipment failure due to overheating. Controlling humidity levels reduces the corrosion risk to the vessel’s structure and onboard equipment. Thus, proper ventilation is essential for maintaining the vessel's functional and operational integrity.
A number of specific ventilation standards must also be met for the vessel to comply with international maritime regulations, pass required inspections, and receive certifications.
Marine vessels use numerous vents throughout the various compartments where proper ventilation is required. Each vent type serves a unique purpose. For example, Dorade boxes, also known as dorade or cowl vents, use natural airflow to ventilate enclosed spaces, typically without allowing water ingress.
Mechanical vents such as axial and centrifugal fans help to move air in ways that are unique and specific to their applications, while louvered vents have slats that can be angled to control airflow and prevent water ingress. These are seen most commonly in machinery spaces and storage areas to provide ventilation while protecting against rain and sea spray.
The types of vents used in the marine industry are too numerous to provide a complete listing in this space. Proper selection and maintenance of vents are crucial for ensuring marine operations' safety, comfort, and efficiency.
