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 trial to investigate between hull and waterjet propulsion. Flow rate is corrected by bollard pull test and shaft power is measured directly using a torque meter. The measured results are compared with the predicted results on the basis of DB. Those experimental data will be useful for the future works to develope the model test method and method for powering performance prediction.
