Wave Load and Strength Analysis of Truss-Floating Box Aquaculture Vessel

Abstract

There are no specific codes or rules for designing a new truss-floating tank aquaculture vessel developed in recent years. Moreover, relevant rules for ships and offshore structures are usually referred to in different design stages. However, the floating way and the structure of the truss-floating tank aquaculture vessel are different from those of any ship or offshore platform. According to the code of ship or ocean engineering, there will be significant errors in the design. Firstly, loads of vessels at different sea conditions are calculated using SESAM software. The stresses of the truss-floating tank aquaculture vessel are numerically simulated in accordance with the maximum loads. Furthermore, the global longitudinal strength can be evaluated. The sensitivity of the vessel’s strength to wave parameters is analysed. The research results can provide a valuable reference for designing a truss-floating tank aquaculture vessel.

Hydrodynamic and Structural Optimization of a Truss-Floating Aquaculture Vessel

“…To address this gap, we performed a structural optimization of a truss-floating aquaculture vessel in our prior research [27,28]. However, our optimization analysis was confined to a parameter optimization involving continuous design variables.…”

“…However, our optimization analysis was confined to a parameter optimization involving continuous design variables. Typically, the sole optimization objective is the weight of the entire ship structure, encompassing the fatigue analysis of truss joints [27] and the assessment of buckling and yield strength [28]. In this paper, we apply the adaptive simulated annealing algorithm and multi-island genetic algorithm to optimize the maximum stress, maximum deformation, and overall weight of the vessel.…”
