Effects of Transom and Skeg Angle on Barge Drag and Seakeeping

Abstract Skeg in barge maintains stability, while transom is responsible for influencing the fluid resistance of barge. Therefore, this research aimed to discuss the effect of angle variations in skeg and transom on resistance and seakeeping. Analysis was performed on variables such as drag coefficient to angle variation, RAO to the response given by waves in translation and rotation, and the value of wave frequency. The analytical results showed that the variation of transom below the waterline increased the resistance of barge while the variation of skeg angle affected barge’s stability and maneuverability. Additionally, seakeeping analysis obtained data to understand barge in various sea weather situations. This signified that each varied skeg angle affected drag and seakeeping effects. Following this exploration, the research is expected to contribute to barge technology.
