INSTRUMENTED FREE-RUNNING MODEL TESTS – THEIR APPLICATION TO SMALL HIGH SPEED CRAFT

S Phillips, I Shin, C Armstrong, D Kyle-Spearman, Seaspeed Marine Consulting Ltd

SUMMARY

The use of instrumented free-running hydrodynamic models has recently enabled significant advances to be made in the understanding of high speed craft performance at sea. This paper outlines the benefits and challenges of this approach with reference to SAR vessel designers, to leading suppliers of fast wind-farm support catamarans who are using this technology to specify their new craft and to the builders of very fast monohull craft investigating high speed dynamic stability. Free-running model testing provides data that is not readily available from CFD or conventional tank testing programmes, in particular handling and manoeuvring characteristics, the assessment of limiting conditions such as bow diving, high speed dynamic instability, slamming characteristics and the craft’s performance in extreme sea conditions.
