MODELLING OF MANOEUVRING WITH ATTENTION TO SHIP-SHIP INTERACTION AND WIND WAVES

摘要

CFD and simplified modular manoeuvring models are discussed with emphasis on ship-ship interaction. The importance of ship end effects on ship-ship interaction necessitates a 3D analysis. A limited error analysis for a modular manoeuvring model is applied to a single ship in calm water. How to account for wave effects by means of mean wave loads is briefly described. A method to predict mean wave loads on a single ship as well as on interacting ships at forward speed is presented. Satisfactory agreement between numerical simulations and experiments of the trajectory of the SR-108 container vessel in a turning manoeuvre in regular waves is demonstrated. The presence of resonant water motion in the gap between two ships is discussed and a simplified method to account for flow separation at the gap entrance is presented. It is discussed how to generalize the method to ship manoeuvring.
