can be quickly mobilized and repositioned. The platforms are also easily recyclable at any time t and obviously at the end of the equipment's life.

Ocean waves

is universally available and of variable power according to the latitudes. Its exploitable production potential is 2,000 to 8,000 TWh / year worldwide .

The modular SEACAP platform.

SEACAP , a simple and robust marine energy capture and conversion (PTO) system. Disruptive, although essentially based on known technological modules, proven in offshore oil for decades (platforms operated in very difficult environments).

The heart of the energy production system is made up of Direct Drive Switched Reluctance Linear Generators (AMSRM) , controlled by latest generation electronics. This constitutes a considerable advance in terms of renewable energy production, performance, security and therefore ultimately cost (LCOE) of the carbon-free energy necessary for the energy transition.


The design of the platforms also makes it possible to produce green hydrogen in situ and thus to free oneself from the intermittence of the marine resource or, alternatively , to supply the clean energy mobility market, currently consuming hydrocarbons. Likewise, many other industrial activities, apart from very polluting heavy land and sea transport, will be able to benefit from this production of hydrogen.

It is notable to note that in France in particular, electricity is mainly of hydraulic and nuclear origin. It is already very carbon-free (even if this latest technology induces other very important problems of investments, safety, transport, waste, etc.) and, that it is therefore the non-electric portion of the total energy consumed (70%) that needs to be transformed.

High-performance multifunction platforms


Steel or concrete monopile, on an anchored gravity or suction base that can be subjected to the most extreme conditions. Equipped with a float, activator of linear generators, the captured energy of which can be directly exploited on the deck or evacuated to the terrestrial network.

Electronic power controller

State-of-the-art electronics for real-time control of the resource and generators as well as the level and type of production chosen.

Exploitation is controlled by a Scada system from the coast, making offshore interventions very infrequent.

Champs houlomoteurs

Rows of Seacap platforms of sizes and powers adjustable to your projects and in all environmental conditions.

Typically a field will be studied for a total power of 200 to 300 MW able to operate on average 4000 h / year.

Linear generators

Innovative and efficient switched reluctance linear generators to achieve a high level of density and high continuous and maximum force. In the process of being finalized within the framework of the “H2020 Seatitan” project bringing together several European partners, tests are scheduled for the near future.


By light naval means.
A floating version similar to a SPAR type column for great depths will be derived later.

Float (activator)

Size and weight adjustable according to the sites and their environmental characteristics.

Innovative generators

Modular generators easily installed, or replaced in the event of scheduled or accidental maintenance, by standard exchange and without excessive downtime. 

Without unnecessary mechanical transfers, reducing the power and costly in maintenance.

Direct production from the swell to the electrical outlet

A new generation of innovative and efficient direct drive, switched reluctance generators providing a higher force density than rotating machines, without the use of permanent magnets.

Operational management

Economical maintenance thanks to its Modularity and Scheduled maintenance

continuous proactive surveillance by a Scada network operated from the coast

less frequent and more economical interventions, inducing smaller OPEX

Reinforced safety for operators and equipment
