The present report is part of the technical documentation of the PRIAMO project(Propeller-Rudder Interaction Analysis and MOdelling) and is focused on the development of a comprehensive hydrodynamics and hydroacustics modelling tool for the analysis of propeller/rudder interactions. The hydrodynamic analysis is achieved through a 3D, unsteady solver based on the Boundary Element Method for lifting bodies. On the other hand, two approaches for the prediction of field radiated noise based on the Bernoulli theorem and on the solution of the Ffowcs Williams & Hawkings equation, respectively, are discussed. Finally, propeller and rudder sheet cavitation modelling is addressed. This report collects the description of all the theoretical models developed within the project, whereas their validation is faced in other reports.

Abstract
The present report is part of the technical documentation of the PRIAMO project(Propeller-Rudder Interaction Analysis and MOdelling) and is focused on the development of a comprehensive hydrodynamics and hydroacustics modelling tool for the analysis of propeller/rudder interactions.

On the other hand, two approaches for the prediction of field radiated noise based on the Bernoulli theorem and on the solution of the Ffowcs Williams & Hawkings equation, respectively, are discussed. Finally, propeller and rudder sheet cavitation modelling is addressed.
