The Crestwing Wave Energy
Converter works on the
surface of the ocean
and
consists of a line of
connected, floating
pontoons. The first pontoon
is anchored at the seabottom,
and there is supportive
anchoring from the mid of
the last pontoon.
In this presentation I have employed two pontoons. The connected pontoons of the system are reflectable by the hinges, when the crest of the waves passes under the floating devices. The formation of angle-movements is transformed to useful energy due to a PTO system.
The pontoons are pushed upwards from the below passing wave and again drag down by the same passing wave. Complex hydrodynamic conditions arise below the pontoons, when wave formations are pushing the device up and down simultaneously. The working order of the system is a potential system as well as a dynamic system.
In full scale The Crestwing in The North Sea will be approximately 80 m long and 18m width, with 2 power conversion pontoons per machine. Each machine with a rate of 1 MW. The energy produced by The Crestwing (WEC), of course, depends on the conditions of the installation site. In the North Sea each machine will, on average, produce more then 1 GWh per year. In The Atlantic Ocean, baced on a simple up-scale, each machine can provide sufficient power to meet the annual electricity demand of approximately more then 2000 homes with an average consumption of 5000 kWh a year.
