    • Abstract

  • The hydrodynamic load on netting has a significant impact on the force and motion of aquaculture platform. To determine the hydrodynamic load on netting of different materials and structural forms, by studying the structural and material characteristics of netting, we designed the standardized calculation methods for the hydrodynamic load factors on fiber netting and metal netting. For fiber netting, we set a formula for calculating the solidity of netting applicable to different mesh shapes. For metal netting, we set a formula for calculating the hydrodynamic load factors equivalent of netting applicable to different mesh shapes. Besides, we analyzed the impact of mesh shape on the hydrodynamic load factors of netting. The calculation results show that when the mesh edge length was the same, for knotless fiber netting, the hexagonal netting experienced the least hydrodynamic load factors. For metal netting, the rectangular welded netting experienced the least hydrodynamic load factors. The findings provide a reference for the selection of netting types and hydrodynamic load calculations for fishery platform.
