Investigation of Fishing Vessel Operability for Various Loading Conditions

Mr Muhammad Iqbal, a PhD researcher at the Department of Naval Architecture, Ocean and Marine Engineering at the University of Strathclyde is using Computational Fluid Dynamics to conduct research on the behaviour of small fishing boats with a view of improving their safety and operational efficiency. Fishing boats possess distinct characteristics that make them vulnerable to changes in loading conditions. When these boats depart from the port, their empty fish tanks gradually fill up during fishing operations, leading to a hazardous occurrence known as parametric roll, which can result in capsizing. The main objective of this study is to gain a deeper understanding of parametric roll in fishing boats and its correlation with shifting loading conditions.

The research examines the influence of displacement and the GM/KM ratio on parametric roll, as well as the longitudinal flare distribution at the waterline. To detect the occurrence of parametric roll at an early stage, two assessments were conducted. The first assessment utilized the level 1 criteria of parametric roll based on the Second Generation of Intact Stability criteria from the International Maritime Organization (IMO), while the second assessment utilized the Susceptibility criteria of Parametric Roll from the American Bureau of Shipping (ABS).
Additionally, Computational Fluid Dynamics (CFD) was employed to predict the amplitude of the parametric roll phenomenon. The findings offer valuable insights to fishing vessel operators on how to manage loading conditions effectively to maintain stability and prevent hazardous situations. By adhering to the guidelines outlined in this study, fishing boats can operate with improved safety and efficiency, thereby reducing the risk of accidents and enhancing the overall sustainability of the fishing industry.
