Main requirements for ventilation of different rooms on the ships

Abstract

The ventilation system is vital for the good functionality of the vessels and its purpose is to ensure the requested environmental condition for equipment and people. In addition, the ventilation system is assuring the safety of the vessels by reducing the concentration of the flammable and toxic gases which can escape from the equipment, systems, and storage tanks. Also, in case of fire, the ventilation system must be able to extract the smoke from engine rooms and public atriums spaces in passenger's vessels. The paper is a short over-view of the main requirements and recommendations for ventilation systems of different compartments on the vessel and different types of vessels. The requirements related to the safety of the vessel and people on board are stated in Class and IMO / Administration rules and regulations while the calculation of the air flow needed to remove the heat radiated inside the room is indicated in ISO standards.
