AbstractIn a recent study to evaluate the occupational risks induced by ship motions on the fishing fleet of Newfoundland, a model of a 65? fishing vessel fitted with paravanes was tested in the Ocean Engineering Basin (OEB) of IOT. This project was done under a larger umbrella community initiative called SafetyNet to evaluate health and safety issues of the fishing industry. The particular focus of this project was to evaluate motion induced interruptions onboard the fishing vessels for various operational scenarios. Paravanes are the most common motion reducing devices used on Newfoundland fishing vessels. Paravanes were initially modelled by scaling down both the geometry and the weight using Froude scaling laws. This modeling strategy proved to be unsuccessful and several modifications to the paravanes were required throughout the test program. This paper describes the model seakeeping tests with particular focus on the challenges encountered in modeling the paravanes for these tests. Some of the tests results obtained with and without paravanes deployed will be included in the paper (Fig 1).
