This paper presents preliminary results from a computer program for simulating ship maneuvering in ice covered waters. The program is derived from two programs, Ship Maneuvering Laboratory (SML) and a discrete element numerical modeling program (DECICE). SML is an in-house code developed by Oceanic Consulting Corporation for simulating ship maneuvering in open water. It is based on a ship maneuvering model originally developed by the Japanese mathematical maneuvering group (MMG). DECICE is a discrete element method which was developed by INTERA Technologies and is used to calculate the ice loads on the ship and the interactions between ice pieces. The paper presents a summary of the mathematical methods used together with the results of some case studies for ships EXM004, PSM004 and Esso Osaka Tanker. These computer predictions include turning circle and Zig-Zag maneuvers. Comparisons and discussion of the simulated results between cases with and without ice are also provided.Copyright © 2010 by ASME |
