Abstract

This paper describes the design and construction of a test ship with waterjet propulsion system for sea-trial test. Local flow characteristics around intake and nozzle of a operating waterjet propulsion system are measured at a sea to understand interaction between hull and waterjet propulsion. Those experimental data will be useful for the future works to develope the model test method and method for powering performance prediction. The monentum flux method which is recommended by 21th ITTC is adapted for analysis of measured data. Flow rate is corrected by bollard pull test and shaft power is measured directly using a torsion meter.
