Dynamic Responses of a Bottom-Set Gillnet Anchored to Seafloor Using Measured Environmental Data in the Southwest Coast of Korea Conference Paper

abstract

• 2018 IEEE. Dynamic-analysis results of a 300-m-long bottom-set gillnet are presented under wave excitations and current. A bottom-set-gillnet design is based on one of existing types utilized in South Korea. Environmental conditions are chosen based on measured wave and current data obtained from the southwest coast of South Korea. The cruder equivalent net model is designed by matching projected drag area and wet weight to save computational time in time-domain simulations. The Morison-force model is utilized to calculate hydrodynamic forces acting on the entire gillnet. Stretching performance of the modelled gillnet is good even at low current velocity. Motions induced by wave excitations are small in operational conditions at given submergence depth, whereas significant variations occur for the fishery-prohibition condition.
