Marine Dynamics Research Group

MARINE DYNAMICS

 This group conducts a wide range of research on the maneuverability performance of moving bodies in the ocean, focusing on ships, including research on new-type ships such as advanced sail-assisted ships and technological development of underwater robots.
 In these studies, this group conducts various experiments depending on the purpose as follows:

  • Experiments in the actual sea model basin using the free-running and captive model.
  • Captive model experiment in 400m towing tank/150m towing tank.
  • Load measurement/visualization experiment in pulsating wind tunnel with water channel.
  • Underwater robot experiments in the deep sea basin.
  • Actual sea area experiments for large ships and small planning boats.
 This group conducts analysis and investigation of the causes of marine accidents and technically responds to international and domestic standards for safety. This group also carries out research projects inside and outside the institute and undertakes various contracts and joint research. This group hopes that its activities contribute to developing safe and advanced maritime technology.
