For these reasons it has been decided that the more constant
electricity required for the passive cleanup, 66.5 kW
(22+ 2 + 37.5 + 5), will be generated by means of solar and
possibly wind power, and that the 180 kW for the shredder
and transshipment will be generated using a diesel
generator. This means that the system will work 20 hours
per day on the battery and 4 hours per day on a combination
of diesel and solar power.
4.5.2 Power generat ion
To ensure a constant supply of power, the total consumption
of the system in different situations must be assessed.
The situations considered were: emergency, normal
ocean conditions, and transshipment.
Using the outcome of this analysis, the various energy
generating options can be assessed. As shown in Table
4.19, 66.5 kW will not be needed at all times: an average
load factor of 0.9 is enough to ensure continuous operation.
This means that a total of more than 60 kW must be
generated using solar panels on the platform to provide
power for normal ocean conditions. With an average of
160 Watt/m², a solar panel field of around 400m² would
be required.
