ture from the same university in 2005. He has worked
in the United Kingdom, Singapore, and in Australia
with Arkitek Tenggara, Minifie Nixon Architects, and
Monarchi. His research interests lie in the confluence of

tures (VLFS), Informal Settlements, and Global Urban
Projects.
Notesoncontributors ix
Seiya Yamashita graduated from Yokohama National
University in 1968. He joined the Research Institute
of Ishikawajima-Harima Heavy Industries Co. Ltd. and
engaged in the study on propulsive and seakeeping per-
formancesofships.Laterheworkedonthewave-induced
forces and motions for offshore structures such as box-
shaped floating vessels, semi-submersible drilling rigs,
and floating breakwaters. He received his Doctor of Engineering in 1986
fromtheUniversityofTokyoforhisstudyonhullconfigurationforoffshore
structures on which wave-exciting forces are not exerted in waves. From
1995 to 2000 he joined the Mega-Float project in Japan as a member of
the research on hydro-elastic analysis for a VLFS. He is now a part-time
managerofshipandmarinetechnologydepartmentofIHICo.Ltd.
TomoakiUtsunomiyaisAssociateProfessorofCiviland
Earth Resources Engineering at Kyoto University, Japan
andhasundertakeneducationandresearchintheareasof
OffshoreStructuresincludingVeryLargeFloatingStruc-
tures (VLFS) and Floating Bridges. He has published
about 170 papers and books in these areas. His main
research interests include hydroelastic analysis of Very
LargeFloatingStructure.Partofhismajorcontributions
in this area are “An eigenfunction expansion-matching method for analyz-
ingthewave-inducedresponsesofanelasticfloatingplate,”AppliedOcean
Research, 17 (1995); “Wave response analysis of a box-like VLFS close to
a breakwater,” Proceedings of the 17th OMAE (1998); and “Fast multi-
polemethodforwavediffraction/radiationproblemsanditsapplicationsto
VLFS”,IntJOffshorePolarEng,16(2006).
MasahikoFujikuboisProfessorattheDivisionofStruc-
tural Engineering, Department of Social and Environ-
mentalEngineering,HiroshimaUniversity.Hegraduated
from Osaka University in 1979, and received his MSc
in 1981 and PhD in 1988 from Osaka University. His
research areas are the ultimate strength and structural
reliability of ships and offshore structures, and non-
linear structural analysis. He stayed in the Norwegian
University of Science and Technology from 1988 to 1989 to do research
on the assessment of ductile fracture of offshore tubular structures. He
was engaged in the Mega-Float project in Japan from its initial phase as
a technical advisor for structural design and analysis. He published a text-
bookStructuralDesignofVeryLargeFloatingStructurefromSeizando(in
