BULK CARRIER OPERATIONS SAFETY ENHANCEMENT PROJECT. PHASE II, VOLUME I. TANK ATMOSPHERE CONTROL

An experimental study was conducted utilizing scale modeling techniques to establish improved methods for ship tank gas freeing and inerting. Scaling studies were performed to establish appropriate similitude criteria. Parametric studies were undertaken to investigate the effects of tank internal geometries, inlet/outlet configurations and locations, blower flow capacities, and gas densities on the gas exchange process. A comprehensive set of experiments was conducted on six ship tank models which represent extremes in tank geometry for U.S. designed and constructed ships. Design and operational information is presented and techniques to improve the efficiency of gas exchange are recommended for both dilution and displacement methods.
