Point of view
“HydroContest is a great adventure that I recommend to all. Such a competition allows you to think about many aspects of a ship. There is something for everyone, those who want to innovate, make 3D drawing, make calculations, do economics, weld, stratify, will be satisfied. You will find your place and you can develop your skills.
Personally, this adventure allowed me to discover materials that are rarely worked at ENSM but that are nevertheless present in the maritime field, to develop my design capabilities and fluid-structure interaction.
The team spirit around this project creates unfailing links that will follow you throughout your life.”
Vivien LUTHY, ENSM participant to 2016 edition
The stakes of maritime transport
Shipping is a major environmental challenge. Although it emits less CO2 per tonne transported than other transport modes, it is responsible for 3% of global greenhouse gas (GHG) emissions, due to its magnitude.
Indeed, the volume of goods transported by sea has quadrupled since the 1970s to reach 13 billion tonnes in 2023.
In this perspective, the maritime sector must prepare for the future by focusing on the energy transition, an urgent need for industry.
A major lever for decarbonisation and maritime innovation
A committed project
For its first edition, HydroContest by ENSM highlights three key sectors in the evolution of maritime transport for a decarbonized future.
- The design and conception of eco-friendly ships of the future: HydroContest By ENSM Design
- The study of an operational transport vessel to improve its energy efficiency: HydroContest By ENSM Hackathon
- The presentation of technological innovations under development to reduce the environmental impact of ships: Hydro Blue Tech by HydroContest
A DESIGN CONTEST
The HydroContest By ENSM competition, an incubator of ideas, brings together future engineers and architects from the international community around a common challenge: “Transport better, faster, while consuming less energy and reducing environmental impact.”
Point of view
“Participating in the HydroContest project is an extremely dense experience in terms of technical and human exchanges. It changes the teacher-student work relationship towards a particularly effective and mutually productive “constructive exchange” that extends to outside of academy partners (technical and financial partners). Each new edition allows to (re)discover and introduce various technical solutions and increase the number of our partners. It is an experience as diverse as it is rich in lessons.”
Frédéric SPELLIERS, EEA Teacher – Initiator of the project for ENSM Marseille in June 2013 and project leader until June 2016
French and international teams
4 teams are now officially registered for the Prototype Contest, and a hundred schools have been contacted to take part in the Hackathon!
A HACKATHON
HydroContest By ENSM offers a unique opportunity to participate in a maritime innovation hackathon. It fosters creativity through challenges and an inspiring competition. Additionally, it incorporates an academic and research dimension by bringing together students, their teachers, and industry partners.
The 2025 edition of HydroContest By ENSM introduces, for the first time, a brand-new challenge focused on rethinking the transformation of an “old ship.” Students are invited to propose solutions to improve the efficiency of these polluting vessels by focusing on aspects such as the hull, propulsion system, or the addition of appendages, while emphasizing environmental considerations. The project should align with the context of the United Nations Ocean Conference (Nice, 2025).
HydroContest By ENSM 2025: A Hackathon Setting Sail for Sustainable Maritime Transport!
HydroContest By ENSM 2025 is breaking new ground by launching a Hackathon dedicated to the decarbonization of maritime transport. This unique event will bring together students and industry professionals to tackle a strategic challenge: imagining disruptive solutions for a more sustainable and efficient maritime transport sector, with a focus on retrofitting an existing vessel.
A Marathon for Ecological Transition
For over two months, participants will work in teams to develop concrete projects, ranging from optimizing vessel energy efficiency to integrating artificial intelligence for smarter navigation. Guided by academic mentors and the HydroContest By ENSM team, they will receive technical and methodological support to turn their ideas into real-world solutions.
A Challenge with Real-World Impact
This Hackathon is part of the HydroContest By ENSM initiative, an internationally recognized event driving sustainable maritime innovation. At the end of the competition:
🏆 The top three projects will be awarded.
🔟 The 10 best projects will gain visibility among key industry players.
🥇 The winning team will receive a special prize and may even take part in deploying their solution on the designated vessel.
Why Participate?
✔ Full immersion in maritime innovation.
✔ A unique opportunity to collaborate with experts and leading companies.
✔ A spotlight on the most promising talents and ideas.
“HydroContest By ENSM 2025 continues to push the boundaries of innovation and unite a committed community for the future of maritime transport.”

Simon BERNARD
“Participating in the first edition of HydroContest in 2014 and winning the Innovation Award with my team was a foundational experience, marking a turning point in my journey and undoubtedly contributing to the success of the Plastic Odyssey adventure. Far more than a technical challenge: it is a window into entrepreneurship, teamwork, and the complexity of naval engineering and architecture. This experience convinced me that the best way to learn is to be at the heart of the action, finding solutions on your own.
HydroContest also helped ENSM gain international visibility and build strong connections between universities worldwide. This adventure was truly a springboard for me, sparking my desire to innovate and create solutions to preserve our oceans. I am deeply grateful for this experience and fully support the new edition of HydroContest, convinced that it will continue to inspire and encourage new vocations.”

“To the public, this event will represent much more than a series of competitions. It will reflect our collective commitment to innovation, ecological transition, and solidarity. It will offer an immersive, educational, and inspiring experience where every participant can feel like an active player in this ambitious adventure. It will be a significant moment, symbolizing unity between generations and skill sets, and the growing importance of eco-responsibility in the maritime sector.
Being the godmother of the first edition of HydroContest By ENSM, after having studied at Hydro myself, is both a personal and professional recognition. Contributing to a project that embodies creativity, research, and technical prowess, while promoting values for a future respectful of our planet, fills me with pride. It is an honor to be the ambassador of values dear to me and to support younger generations in their journey toward excellence.”
