Dive into the depths of marine aquaculture dynamics! The surge in demand for marine proteins, coupled with stagnant wild fish catch, propels the growth of bivalve farming. But with near-shore space running scarce, research is venturing offshore.

In our study, using cutting-edge results from our large-scale wave tank facility (GWK), a novel numerical model to estimate the forces on submerged dynamically moving mussel dropper lines is introduced. Drag and inertia coefficients (CD = 1.1 and CM1.7, respectively) are recommended for modeling. The numerical model, based on a modified Morison equation, considers mussel dropper line displacement.

Aquaculture-related parameter influences are discussed, providing engineering insights for optimal mussel aquaculture placement in the water column.
