In this paper, the results of experimental investigations of the characteristics of the flow behind a twin-propeller twin-rudder hull are presented. An Acoustic Doppler Velocity meter (ADV) was used to measure the flow field behind the twin propeller and twin rudder. The measurements were mainly carried out in zero speed condition. Additionally, few experiments were carried out with model moving in bare hull condition, i.e. without rudder and propeller. This data was used for verification of CFD simulation result. In the zero speed condition, experiments were carried out with propeller rotating in inward and outward configuration respectively. Phase averaged measurements were also carried out for the port propeller in outward rotating configuration, in the zero speed condition. Numerical prediction of propeller thrust and torque at zero speed condition are under development. The experiment data presented in this paper will be useful for validation of numerical methods under development.
