Seakeeping of a Non-Wall Sided Vessel in Shallow Water: Lessons Learnt From Experiments and Numerical Analyses

Extensive model tests of a soft moored LNG carrier in shallow water have been performed in 2004. The focus of this test campaign was on the hydrodynamics of non wall-sided, low drag vessels and the characterization of the model basin performance. The motivations behind this test campaign have been discussed in ref [1] and [2]. Numerical calculations have been performed using industry state of the art tools and compared to experiments. Having uncovered differences, further numerical investigations have been performed with a nonlinear potential time domain solver. Comparison between experiments and numerical predictions will be presented for monochromatic waves in 30m depth. Lessons learnt in the process will be highlighted.
