NICOP - Study of Damaged Ship Maneuverability Based on Towing Tank Tests and Mathematical Maneuvering Models
Abstract
Study of Damaged Ship Maneuverability Based on Towing Tank Tests and Mathematical Maneuvering Models:a. Technical: With increasing interest in operational safety of naval vessels and commercial passenger ships, dynamic stability and maneuverability of damaged ships are the most important problems. The problem is very difficult due to its highly complex physical nature. The proposed study aims at developing mathematical modeling for damaged ship maneuverability. Development of maneuvering equations of motion for ships in damaged condition will be carried out based on captive model test results. An public domain U.S. Naval combatant hull form will be used as the sample model in this study. Free-running tests in an open lake and computational fluid dynamics (CFD) simulations will also be conducted to create database for maneuvering coefficients, as well as for validation of the mathematical model. b. Relevance: With increasing number of terror attacks on military vessels worldwide, it is of utmost concern to understand the stability characteristics and maneuverability of ships in damaged conditions. It is not only to evacuate or rescue the vessel and its crew, but also to provide guidance for better protected navy vessel designs in the future. Damage control guidelines for increasing survivability in flooded condition will also be provided based on the damaged ship maneuvering characteristics identified in the study. This effort directly support the U.S. Naval ~Platform Design and Survivability~ S&T focus area. c. Coordination: ONR code 331 (Dr. Thomas Fu) d. Desired outcomes: (1) a comprehensive experimental database for CFD validation for ship in damaged condition including forward speed, (2) CFD simulation of ship in damaged conditions operating in waves and with forward speed, and (3) archival level technical papers to enhance the understanding of ship motion and maneuverability in damaged condition in the community
