Abstract

Due to concerns over CO_2 emissions, demand for seaborne trade of Compressed Natural Gas Vehicles and Hydrogen Fuel Cell Vehicles has been increasing and carriage by Pure Car Carriers (PCCs) is becoming essential. Thus, the Fire Protection Sub-Committee of the International Maritime Organization started the development of requirements for safe carriage of such vehicles and the authors are engaged in this task. One of the significant risks owned by carriage of such vehicles is accumulation of hydrogen and natural gas, which are lighter than air, under ceiling in case of leakage. Though the accumulation of gases depends on air flow, air flow in cargo spaces in PCCs has not been evaluated. The purpose of the research is to provide a basis for the research on the prevention of accumulation of gases by grasping actual air flow in such cargo spaces. We measured air flow on PCCs occupied by vehicles while berthing under some typical ventilation conditions during voyage, and almost calm positions were observed depending on ventilation condition.
