NONLINEAR SHIP ROLL SIMULATION WITH WATER-ON-DECK

Vadim Belenky, Daniel A. Liut, Kenneth Weems

Open publisher page 12 citations

Abstract

SUMMARY This paper discusses a computational simulation for ship motions, including the effects of green-water-on-deck, and analyzes the predicted rolling behavior of a 21-meter fishing vessel with various computational options. The simulation has been performed by integrating water-on-deck flow into the LAMP (Large Amplitude Motion Program) nonlinear time-domain ship motion and load prediction code. The principal water-on-deck flow model is a finite-volume solution of the shallow water flow across the deck, which is described in detail. The fishing boat simulations are analyzed with the intent of qualitatively evaluating the prediction of expected rolling behavior and the effects of water-on-deck.
