The AMBA & BGA Excellence Awards 2022/23, held on December 9, 2022, at the Biltmore Hotel in London, gathered leading figures from the global business education community to celebrate excellence and commend exceptional achievements in business schools, MBA students, graduates, suppliers, and employers. 

As the event unfolded, Damien’s win for MBA Startup of the Year stood out, highlighting the value of startup business strategy and innovation in the competitive business landscape. 

Greenov, founded in January 2021, is on a noble mission—to protect marine ecosystems through maritime clean technology that minimize anthropic impacts. Embracing maritime Clean Tech, the french start up introduces the SubSea Quieter—a groundbreaking technology designed to shield marine ecosystems from noise pollution linked to maritime port and offshore works, including the installation of offshore wind turbine foundations. 

With 14 dedicated employees and a commitment to growth, the start up has earned prestigious recognition, being selected for the highly selective « Accelerator » program of the European Innovation Council (EIC). This has granted them €2.39 million in subsidies and an entry into the EU’s capital for the next funding round. Greenov’s achievements also extend to winning the esteemed Port of the Future 2022 Innovation Awards.

 A Great Ocean Hackathon 2023

Thrilled to announce our continued commitment to driving positive change in ocean conservation! Greenov, actively engaged in projects SafeNav and LIFE – SeaDetect, has decided to renew its participation in the Ocean Hackathon 2023 by campus de la mer.

Building on our success in the 2022 edition, GREENOV embraced the challenge once again, collaborating with a stellar team including Romain JAN, Ludovic Mell from Greenov, Anna, and Abel from Sciences Po, Mickaël from ISEN, and Pierre from ENIB.

Harnessing the power of AI and trajectory optimization algorithms, our team showcased innovative solutions to mitigate ship-cetacean collisions. Our findings underscore the need to reshape our consumption and travel habits for meaningful impact, addressing issues like collisions, noise, and greenhouse gas emissions. To recognize environmentally conscious shipowners, we even proposed the creation of a label, complete with a logo crafted with the assistance of the fablab at IMT.

Big shoutout to the entire Hackathon organization and our coaches, especially Emeric and Sophie, for their invaluable support. Kudos to the team for their dedication and innovative spirit! Let’s continue making waves together for a sustainable future.

Echo Bruit magazine – get to know the SubSea Quieter

We are thrilled to be featured in echo bruit magazine number 176, page 18-19!

Our Chief Business Officer, Gwenael Desse, dives deep into the innovative technology of our noise mitigation system, the SubSea Quieter.

Big thanks to CidB – Centre d’information sur le Bruit for this fantastic opportunity to share our commitment to a quieter and sustainable future. Stay tuned for more updates on our groundbreaking developments! 

Tip & Shaft Event

 We were delighted to attend the Tip & Shaft event for the first time, dedicated to Offshore Racing. Through engaging discussions and presentations, we witnessed the dynamism of this industry and the strong commitment of its stakeholders towards the protection and promotion of the maritime environment.​

The topic of reducing collisions between cetaceans and ships sparked significant interest, underscoring its critical importance to the Offshore Racing players (teams, IMOCA Class, sponsors, suppliers). This only reinforces our determination to channel all our energy into finding innovative solutions within the scope of our two European projects: SEADETECT and Safe Nav.​

Thank you to everyone we had the opportunity to meet:​

Noise mitigation system: another key milestone for our innovative SubSea Quieter

Revolutionizing Submersed Noise Mitigation  

Beneath the surface of our oceans, human maritime activities often disrupt the natural soundscape of marine life. Greenov’s innovation, the SubSea Quieter (SSQ), is addressing this issue by offering a practical solution for reducing underwater noise.  

Noise mitigation system

At its core, the SubSea Quieter operates through a simple yet ingenious principle.  Utilizing a waterproof patented membrane to create inflatable panels, it mirrors the concept of double glazing, adapted meticulously to the challenges posed by maritime conditions. This unique membrane, when inflated,  creates an impedance loss for sound waves, resulting in a substantial reduction in noise levels—a significant step forward in minimizing the impact of human activities on marine ecosystems.  

A notable feature of the SubSea Quieter is its modular and adaptable design. It can be tailored to suit various types of maritime work and specific site requirements. This adaptability, combined with a streamlined air management system, ensures that the technology can be integrated seamlessly into different operations. 

Validation of a prototype for the SubSea Quieter’s air management system 

One of the key components of the SubSea Quieter is the Air Management System, which injects the right amount of air at the correct pressure into the different layers of the membrane depending on their depth.  

The Air Management System is made up of several pressure controllers/sensors and a command unit.  It is made so the operator can control manually the pressure in the different panels (within security margins) or let the system regulate the air pressure and flow automatically. 

The testing phase of that particular air management system, conducted in the first quarter of 2023, marked a pivotal point in the SubSea Quieter’s journey. The aim of the tests was to validate the System’s principles and functioning in water. Despite being made at a small scale, this test provided valuable insights, affirming the concept’s feasibility while pinpointing areas for improvement.  

The technical requirements induced by pile driving led to a particular idea—the development of a system that manages the air from a watertight enclosure near the panel. This approach emerged as the most practical solution, avoiding potential technical and logistical complications. This innovation highlights Greenov’s commitment to adapting and evolving its technology to real-world conditions.

This test is the first in a long series that will run during 2023 and 2024. The various subsystems will be tested individually before being progressively assembled. The Greenov team’s objective is to be able to carry out the first test of the SubSea Quieter Pile Driving in February 2024 in the port of Saint Nazaire (France). A 10 m long and 5 m in diameter system will be tested.
