Safety, performance, improved
comfort and staff security, reduction in GHG emissions and atmospheric
pollutants ... these are the main objectives that Louis Dreyfus Armateurs,
Mauric, Barillec Marine, SEAir and ADV Propulse aim for thanks to the ZEST
industrial consortium. The five partners have been working for three months
on the development of a prototype CTV which is safer when transferring
personnel and tends towards "zero emissions".
Thanks to the ZEST project, a new type of innovative and more energy-efficient
CTV will emerge in 2025. This CTV will provide a safer and more efficient
transfer of wind turbine maintenance personnel, due to its excellent sea
navigation characteristics and the integration of sea state monitoring
systems. In comparison to the current market for wind turbine maintenance
personnel transfer vessels, it will offer a more suitable and secure solution
for transfer operations at sea, will be more manageable and better suited
to maintenance operations.
ZEST will operate with low energy consumption and greenhouse gas (GHG)
emissions thanks to the combination of innovative technological bricks
and an optimized architecture. The use of recyclable composite materials
will improve the environmental impact from the construction of the ship
until its dismantling. All of these impacts will be assessed through a
Life Cycle Analysis.
By getting closer to zero GHG emission while gaining operational and safety
capacities, the CTV ZEST will therefore have a privileged spot in a growing
market. By becoming the new standard for CTVs, with very high operational
and environmental performance and relying on the skills of the French maritime
industry, the CTV ZEST will generate several tens of millions of euros
in turnover and create nearly a hundred jobs by 2030 for the French maritime
industry (equipment manufacturers, architects, shipyards, shipowners).
The project milestones
Thanks to the establishment of this consortium, the design studies of the
ship and the associated technological bricks are currently being carried
out, in parallel with a technical and economic study.
The technological building blocks of the project are as follows:
- An innovative CTV
architecture with foils
- Innovative trochoidal thrusters
- The integration
of “Zero emission” GHG energy system solutions
- An innovative
energy consumption management system
- A wave monitoring and floating object detection system
- Depending on market
needs, an adapted dynamic positioning system
At the end of this study phase, the consortium will aim for a first commercial
order which will allow the construction of a demonstrator. This demonstrator
will be tested in real conditions over a period of 6 months to validate
its level of operational safety and its technical, economic and environmental
performances.
The technological bricks developed within the framework of this project
will be suitable for CTVs or other types of ships. Indeed, ZEST is only
one possible application for these technological bricks and will thus be
a showcase demonstrating their efficiency in a context of pressing constraints
to reduce the carbon footprint of maritime activities.
About Louis Dreyfus Armateurs
Project coordinator, The Louis Dreyfus Armateurs Group, offers players
in the maritime world innovative industrial solutions adapted to their
needs, and integrated services ranging from the design and management of
ships to maritime operations in the fields of dry bulk transport, logistics
and marine industrial solutions. Present worldwide with more than 2,600
employees and around 100 vessels, LDA is a French family-owned group.
About Mauric
Scientific coordinator MAURIC, subsidiary company of ECA GROUP, is a European
leader of naval architecture and marine engineering, designing, for shipyards
and shipowners, military and professional vessels in the range between
10m and 150m. MAURIC develops since 1945 innovative ship designs with high
operational and environmental performances. MAURIC designed the LOUIS DREYFUS
ARMATEURS’ CTVs that will operate in the Saint-Nazaire Offshore windfarm.
MAURIC will be the architect of the ZEST CTV and the integrator of the
key technologies developed by the partners of project answering to the
requirements of LOUIS DREYFUS ARMATEURS and the Offshore Wind Energy market.
About Barillec Marine
Project partner Barillec Marine has a general know-how in electricity,
electronics and automation for any vessel project: newbuilding, refit or
maintenance. With today’s environmental concerns, the company designs
and integrates innovative systems for the energy management, the electric
or hybrid propulsion to improve the vessel’s energy efficiency, and thus
reduce their carbon footprint. A trustful technical partner, ready to work
with the shipyards to meet the shipowner’s expectations: from the requirement
specification through the full ship’s lifecycle.
About SEAir
Project partner « Hydrofoils to reduce the drag » The SEAir Design and
Engineering office develops, manufactures and installs hydrofoils and their
systems. These appendages, which are usually retractable and servo-controlled,
lift the hulls completely or partially out of the water. This greatly reduces
the drag of the vessels, a pre-requisite for the installation of the propulsion
systems of tomorrow. The SEAir team, composed of naval architects, systems
specialists, CFD, IFS, etc., works on ships from 8 to 30m. SEAir is now
coordinating a major 20m hydrofoil programme, funded by the European Union
(EDIDP).
About ADV Propulse
Project partner ADV Propulse, is a young French company specialized in
the field of maritime propulsion. The company has developed a patented
mechanism for producing biomimetic vertical axis trochoidal thrusters.
This breakthrough technology offers significant advantages in terms of
energy propulsion needs, an exceptional maneuverability, placing ADV Propulse
at the heart of the challenges of tomorrow's maritime mobility. ADV Propulse
markets propellers reversible to hydrogenerators for sailboats and thrusters
for specialized vessels. spécialisés.
