scope:

This International Standard specifies design requirements and suitable calculation methods for the ventilation of the engineroom in merchant seagoing diesel-engined ships, for normal conditions in all waters. Annex A gives graphical estimates of total airflow in the engine-room in ships, divided into: - the airflow for combustion and evacuation of heat emission in the engine-room, excluding the boiler(s), based on the brake power of the diesel engine(s) for propulsion; - the airflow for evacuation of heat emission from the boiler(s), based on the calculated steam consumption at sea. Annex B provides guidance and good practice in the design of ventilation systems for ships' engine-rooms.
