An Ideol spokesperon said the demonstrators are set to be installed in Japan by the end of 2017.
In March, the companies signed a technology deal with Hitachi Zosen to design, engineer and construct the floating platforms.
The platform consists of a square-shaped semi-submerged hull. Ideol said the waterfilled area inside the hull helps to stablise the foundation.
