LOPEZ, Jesús et al. Stress analysis of a submersible longline culture system through dynamic simulation. Lat. Am. J. Aquat. Res. [online]. 2017, vol.45, n.1, pp.25-32. ISSN 0718-560X.

This study analyzed the stresses on a submersible longline culture system subjected to both parallel and perpendicular oceanographic conditions of 0.5 and 1 m s-1 current velocity with 2 to 5 m wave height, using a dynamic simulation model based on the finite element method. Results indicated that when the culture system is submerged, the stress on mooring lines, the main line and whip lines decreases until a 55%. Additionally, changing the direction of the current and waves results in differences ranging from -59% to 312%. It was established that in an environment involving high-energy events, it is structurally possible to submerge the longline culture system in a direction parallel to oceanographic parameters, which could have positive implications for reducing the loss of cultivated biomass and improving productive conditions.

Keywords : mooring line; main line; whip line; farming; oceanographic parameters.
