Hydrodynamic Analysis

AVEVA Marine contains an integrated tool for analysing the hydrodynamics of the hullform, which includes three modules:

The Powering module incorporates a number of well proven empirically derived methods to predict the resistance and powering characteristics of a hullform and its associated appendages.

The Maneuvering module predicts the following ship maneuvering characteristics using semi-empirical formulae for merchant and warships: crash stop, turning, zig-zag and reverse spiral maneuvers.

The Seakeeping module is a strip theory program, employing frequency domain computations for ship motions, added resistance and dynamic loads, taking into consideration both regular and irregular waves. By applying appropriate sea state data, short term irregular responses can be derived which, when combined with wave statistics and seakeeping criteria, provide long term seakeeping performance predictions.

These three hydrodynamic analysis programs can be used in conjunction with the geometry modelling programs in the early stages of the design process, to assess the feasibility of a particular hullform from a ship performance aspect.
