How we started

Damien Demoor

The reading of several reports on the oceans presenting the major impact of human activities on the oceans and their catastrophic consequences leading to “blue deserts” in the short term created a trigger for me as I am very close to the marine environment and fascinated by its multiple and incredible ecosystems.

I then committed myself to this vital ambition for the oceans and mankind. For 6 years I actively worked on the evolution of the R&D strategy of a large French Naval Defense group towards maritime Clean technologies. We have built a significant network of innovation partners on a European scale. In particular, I launched the “SubSea Quieter“, an underwater noise containment system to reduce the impact of marine works, based on 70 years of Naval Group expertise in underwater acoustic discretion.

But this was not ambitious and fast enough and these actions did not target enough the civil maritime sector, which represents the major part of the impacts on oceans ecosystems. I was in daily contact with industrialists and local authorities who were willing but technically unable to reduce their impact on the oceans and their ecosystems.

I then created Greenov with a few visionaries who shared the same ambition of an ecological transition in the maritime sector, with the strong desire to protect marine ecosystems thanks to the tremendous power of technological innovation. In line with the values developed over the last 10 years through my association HTS, Greenov has also developed a rich social mission, in particular for the employment of people with disabilities.

With these common values, our technological expertise, and our European networks, we are today at the service of companies and communities that want to act to reduce their impacts and thus preserve our richest and most valuable common good and that of our children: the oceans.
