During the last three decades hydroelasticity has evolved from a theoretical concept at the outskirts o f naval architecture, staunchly espoused and promoted by few, to a mature science impacting all areas o f marine technology with a wide range o f appeal, from scientists to engineers and designers.
Important factors in this progression have been the prevailing trends for bigger ships, evermore unconventional ships and the rapid emergence o f a variety o f offshore structures, such as ultra-deepwater drill-ship, energy extraction devices and aquaculture artefacts.
Eighteen years have elapsed since the first conference on Hydroelasticity in Marine Technology, held in Trondheim, Norway. This was followed by the second conference in the series in Fukuoka, Japan (1998), the third in Oxford, UK(2003), the fourth in Wuxi,China(2006) and the fifth in Southampton, UK(2009). The content in terms o f applications and structures has varied; the context remained the same, namely promoting the development o f hydroelasticity and its applications and providing a platform for exchange o f ideas amongst scientists and engineers working i n related disciplines.
The papers included in the proceedings o f previous conference cover a wide range o f areas and structures, from aircushion-supported structures to floating bridges, ships and VLFS, the latter ships, including springing and whipping, and relating to novel methods, novel applications, experimental and full-scale measurements and implications o f hydroelasticity on design. There are also papers dealing with impact and flow-induced vibrations.
It is encouraging to observe that, i n spite o f reaching maturity, hydroelasticity still remains a challenging field o f research considering new and old problems that require solution. I am certain that papers to be presented in the conference w i l l generate substantial interest and discussion aiding the progression o f hydroelasticity, as well as the continuation o f the series o f conferences.
Finally, I would like to thank the International Scientific Committee for their support and advice. Class N K are sponsoring this conference and I gratefully acknowledge their support.
