Restricted water effects upon ship manoeuvring are investigated from the full-scale based identification viewpoint. As the resistance increase may be quite accurately correlated with the squat, it is proposed to store in the ship manoeuvring model kernel only data on the ship's squat. The problem of correction factors (multipliers) to be imposed upon ship added masses and hull force coefficients is...
The existing regression models on the bank (wall) effect are compared to one another both dynamically (force level) and kinematically (counteracting helm and hull drift attitude during a steady-state passage along a bank). A small chemical tanker of known hull and rudder hydrodynamics is used as an example of computations. A lot of essential qualitative and quantitative discrepancies have been found,...
Identification algorithms of the ship manoeuvring mathematical model require waterrelated sea trial data on input. However, most of contemporary positioning systems estimate the over-ground motion state vector. Because of that, there is a need to correct sea triaIs. Some methods of sea (ocean) current estimation are considered below, and also its effect upon motion data and subsequent force identification...
