Abstract

This paper presents a ventilation system design process that integrates the key plan and working plan design phases using evolving 3D models to reduce the required number of design manhours. The process is called the Routing-Expanding-Predicting Ventilation (REPV) process. First, the routes of a ventilation system are determined based on a 3D model of the ship engine room, and the dimensions of the rectangular ventilation ducts are expanded to maintain a range of air velocities using the Duct Route Arrangement program (DRAP) in the key design phase. Finally, after the routes of the ventilation models are revised in the working design phase, the air quantities that are deliverable at the duct outlets are predicted using the Flow Rate Analysis Program (FRAP); these two programs can be replaced by many other ventilation analysis methods/programs. The REPV design process is demonstrated using a 4622 TEU container ship, which is driven by a diesel engine, and the predicted flow rates are compared with measurements taken in the ship engine room.
