Abstract: A numerical model of box-shaped net cage is built based on the lumped mass method and the principle of rigid body kinematics. To validate the numerical model, a series of physical model tests are conducted in the wave flume. The numerical results agree well with the data obtained from physical model test. The mooring line force and motion of a box-shaped net are simulated in pure waves and steady current by numerical model and physical experiments. In order to analyze the effect of cage shape on dynamic responses, net cages with a box and column shape are simulated and compared in pure waves and current. The results indicate that the net cage with column shape is more stable and reserve more breeding volume than that with box shape in waves and current action. (C) 2012 Elsevier Ltd.
