Planar Motion Mechanism
PMM test techniques determine force coefficients for mathematical models of motion. Developing and validating numerical models of ships, offshore structures and underwater vehicles operating in open water or in ice-infested waters are NRC-IOT core competencies. These models are used for predictions of manoeuvrability, enabling the design of safer and more efficient marine vessels and offshore structures. They are also used in the development of software for ship simulators, an invaluable tool for training nautical science students and professionals. While PMM techniques have been widely used for open water experiments, their application in ice-covered water, to address Canadian issues, is a novel approach.
