✦ Synopsis

Laboratory experiments were carried out to investigate the performance of an air-bubble barrier and to determine the oil volume passage rate through such a barrier under various oil sample, wind, wave and current conditions. Two empirical equations were derived based on the laboratory data. The first equation determines the relationship between current velocity and the minimum airflow rate required to avoid oil flow through the barrier from the surface. The second equation predicts the dimensionless oil volume passage rate through the barrier under the surface per unit width when the required minimum airflow rate is given in order to prevent oil flow through the barrier from the surface. If the current and wind speed are given, both the minimum required airflow rate for avoiding oil flow through the barrier from the surface, and the dimensionless oil volume passage rate through the barrier under the surface per unit width can be determined.
