Conference Chair Message

Welcome Message

Back in 1977, the first PRADS was held in Tokyo as the 80th anniversary project of the Society of Naval Architects of Japan. After 42 years of many successful triennial symposia, the 14th symposium will be held in Japan again in Yokohama in September 2019.

Yokohama, located just south of Tokyo and being the second largest city in Japan by population, has developed as the gateway for international transportation and communication. Yokohama is also a center of excellence for shipbuilding and offshore engineering, being the right center of various leading universities, research institutes and maritime industries. Yokohama is also full of wonderful tourism opportunities with excellent accessibility from all over the world.

Respecting and standing on the traditions of the past successful symposia, in the forthcoming PRADS, we will encourage the expansion of our scope to new, interdisciplinary or integrated research and active technical interchange and discussion between naval architects, engineers and researchers, working on ships and other floating structures. I hope many people prepare to submit papers and participate in PRADS Yokohama, believing that it will become another successful memory in the long history of PRADS.
