Toyo Construction Co., Ltd. (President and Representative Director: Kyoji Takezawa) participated in the
“WIND EXPO – International wind power generation exhibition” held at Tokyo Big Site during
the period from 15 through 17 of March 2023.
We explained our technology development for further expansion of offshore wind power generation
and increased use of recyclable energy, by giving the presentation of “TLP*1 floating offshore wind turbines”
and “Suction bucket foundation*2 construction demonstration” using a large screen at our booth
(total 12 times a day). At the panel corner, in addition to our technology development, the construction of
a cable-laying vessel and the collaboration with Mitsui O.S.K. Lines, Ltd. were exhibited.
We would like to extend our special thanks to those customers and relevant people who visited our booth.
The Company will advance our technology development and capital investment related to construction of
offshore wind power generation facilities, and will contribute to the spread of offshore wind power generation
of Japan.
TLP method*1: one of the floating systems for floating offshore wind turbines. It is characterized by
the tension mooring with which the floating is stabilized by pulling down below using a mooring foundation
installed at the seafloor. Abbreviation of Tension Leg Platform.
Suction bucket foundation*2: A new foundation type of bottom-mounted offshore wind power generation.
The embedded length is shorter than a pile foundation type such as mono-pile. It is statically penetrated
using negative pressure generated by drainage of inner water.
