Development of Design Charts for Very Large Floating Structures

We propose design charts for very large floating structures (VLFS). The design charts are developed to easily estimate the stress development of VLFS without cost-demanding hydroelastic analysis. To develop the charts, we have carried out an extensive set of hydroelastic analyses for different wave conditions, structural dimensions and material properties. The design charts let us estimate the safety factor corresponding to a certain choice of design parameters such as structural properties and ocean environmental conditions, etc. At a preliminary stage, the use of the proposed design charts significantly reduces time and cost, and also simplifies the design procedure.
