50MW Platform

A 50 MW OC OTEC plant is shown planned on a tetrahedral structure platform, which is designed to raise the floor above the waves, the 48 OC OTEC basic 1,8 MW modules laid out to occupy 1/3rd of the floor plan delivering over 50 MWe and 118M litres of desalinated water per day.

The central 8.7m diameter cold water pipe raises the water from 1000 metres down, directed to the condensers, and then to the cold water return pipes going down 60 metres below sea level. The spent hot water is in turn is delivered back at a depth of 20 metres.

The platform could alternately be planned to be fully occupied by open cycle OTEC modules, delivering 150 MW, and 354m litres of desalinated water per day.
