ShipMo3D Version 3.0 User Manual for Computing Ship Motions in the Time and Frequency Domains
Abstract
ShipMo3D is an object-oriented library with associated user applications for predicting ship motions, with Version 3 introducing modelling of sloshing tanks and U-tube tanks. This report serves as a user manual for ship motion predictions in the time and frequency domains using ShipMo3D Version 3. A companion report serves as a user manual for building ship models that are used as input for ship motion predictions. Time domain simulations can model a freely maneuvering ship in calm water or in waves. SM3DBuildSeaway builds seaway models representing regular or random seaways, including long and short-crested seaways. SM3DFreeMo simulates a freely maneuvering ship in calm water or in a modelled seaway. Several ShipMo3D applications predict ship motions in the frequency domain for a ship with quasi-steady speed and heading. SM3DSeakeepRegular predicts motions in regular waves. The applications SM3DSeakeepRandom, SM3DSeakeepSeaway, and SM3DSeakeepSeawayFromRaos predict motions in random waves. SM3DTimeSeries-FromRaos produces ship motion time series for a ship with quasi-steady speed and heading based on previously predicted motion response amplitude operators.
