The longitudinal strength analysis of aquaculture floating structure in Indonesia sea water

Research output: Contribution to journalArticlepeer-review


The innovation of aquaculture floating structure is developing in the country, where the maritime sector is the potential aspect to improve the country revenue. The design of the aquaculture facility needs to be carried out an analysis about the construction profile so that the floating structure can be able to withstand the wave load applied along the body. This research is done by using numerical methods. The distribution of weight is carried out based on the Cross-Section Area (CSA) graph which the total weight is equal to the light weight of floating structures. The shear stress and bending moment are calculated at the section of mid-ship and it is taken two cross sections which the first one has a full plate in the main deck and the second one have a hatch. The section modulus should be appropriately calculated in the two cross sections. In order to obtain the result of wave load in the irregular wave, the sea states are varied in 3 to 6 to obtain the magnitude of shear stress and bending moment. The output of this research is to know that there are different criteria of stress occurred between two cross sections analyzed. In other hand, the variation of sea state will show the extent to which the cross section is able to withstand the wave load.
