Abstract:
Abstract: (FPB-60) is a type of patrol boat built by shipyard in Indonesia to strengthen the needs ofwater territorial.However, the 20 years age caused a decrease in performance of the vessel. The method used was the harvard guldammer method to calculate water jet system parameters at a maximum velocity of 35 knots such as inlet diameter and nossel diameter, pump power, pump type used and other parameters to obtain Overall Propulsive Coefficient at that speed. In the calculation of water jet propulsion system design, the amount of capacity generated water jet pump system obtained was 4.15 m3 / s with flow velocity on the nozzle/jet of 28.8 m/s. Based on the value of specific swabs of suction (Nss) of 6205.49, the pump for the water jet propulsion system had considered fulfilled the cavitation limit requirement so that it could be used for (FPB-60).
