Oceans of wave energy

Robustness, strength and flexibility

New report gathers technical knowledge behind the Crestwing concept from pool testing, offshore testing at Hirsholmene
and simulations of future plant size and location. NIRAS has produced the detailed technical report:
- After seeing the plant and being involved in the entire test and analysis process, Tordenskiold and the concept itself
seems like a technique that should be worked on constructively to achieve the goal of commercial plants,
says Niels Jørgen Hyldgaard Vittrup, senior project manager.

Crestwings technology is special

Crestwing has solved the biggest challenges of wave energy - the high costs producing the plants, the low power generation and the challenges of accidents. Crestwing is in no way similar to other wave energy plants and utilizes the energy of the waves in a unique way, as the plant mainly utilizes atmospheric pressure for the production of energy.


It is easy to carry out service and

maintenance on Crestwing, as you board the plant as a ship.

Power Take Off

The Power Take Off system is mechanical and converts about 90 percent of the absorbed energy into electricity.


Crestwing has developed a unique anchoring system, that minimizes environmental impact on the ocean and the seabed.

Development phases

The basic idea behind the development of Crestwing, has been to develop a wave energy plant that:

Is stable and safe on the sea.

Utilizes a high percentage of the incoming energy from the waves.

Efficiently transforms the absorbed energy into production of electricity.

Consider maintenance and service.
