N2 - Drag reduction on ship to decrease fuel consumption and achieve higher speeds has became the topic since the last decades. One of the most atractive idea is micro-bubble, in order to reduce frictional resistance. The purpose of this research is to identify micro-bubble drag reduction effect on Self Propelled Barge Model at 1:28 scale. The influences of air injection ratio and speed will also be investigated. Five injection ratio were used in this experiments; 0,2; 0,3; 0,4; 0,5; and 0,6. Experiments were done in the towing tank, member of ITTC. Micro-bubble was injected on bow and midship using two configurations; triangle stern and triangle bow. The results show that triangle stern is the best configuration with 5% - 40% drag reduction at 0,2; 0,3; and 0,4 injection ratio.
