The decarbonization of maritime transport is often perceived as a challenge for the future, dependent on major technological breakthroughs or alternative fuels that are still in the maturation phase.
The decarbonization of maritime transport is often perceived as a challenge for the future, dependent on major technological breakthroughs or alternative fuels that are still in the maturation phase.
At Marfret, experience shows that an effective transition can already be initiated through a pragmatic combination of operational excellence and targeted technological innovations deployed today.
In a sector where environmental performance is inseparable from economic performance, the challenge is not to oppose climate ambition and operational reality, but to make them converge.
Operational excellence: an immediate and measurable lever
Among the most effective levers is reducing vessel speed, often referred to as eco-speed. Simple in principle, this measure significantly reduces fuel consumption and greenhouse gas emissions without requiring heavy investments. At Marfret, this practice is systematically deployed across all routes whenever operational conditions allow. Applied across our entire fleet and supported by rigorous monitoring, it represents a powerful tool for decarbonization.
In the same spirit, Just-in-Time Arrival practices are transforming the way port calls are approached. By adjusting vessel speed, it is possible to avoid unnecessary waiting at anchorage, reduce port congestion, and eliminate superfluous emissions. This voyage optimization, based on coordination between shipowners, captains and ports, perfectly illustrates the value of a systemic approach.
Digital tools supporting onboard decision-making
Next-generation weather routing tools constitute another essential pillar. Marfret uses the Syroco solution, which, through digital twins of our vessels, integrates real-time wind, wave, current and loading conditions to propose optimized routes to the captain. “Syroco EfficientShip represents a valuable tool, quickly adopted by our crews, enabling them to get the best out of the vessel for safe and optimized crossings,” explains Guillaume Vidil, CEO of Marfret. This decision-support system improves vessel safety, punctuality and energy efficiency.
Combined with a wind-assisted propulsion system installed on our Ro-Ro vessel Marfret Niolon, the rigid eConowind sails, this weather routing tool helps maximize energy gains by reducing fuel consumption by 7 to 10%, demonstrating that optimization measures are not limited to newbuild vessels.
Innovation, cooperation and collective intelligence
La réussite de ce plan d’actions repose sur la collaboration : ingénieurs, gestionnaires de flotte, capitaines, fournisseurs de technologies et experts nautiques travaillent ensemble pour adapter les solutions aux réalités opérationnelles. L’innovation maritime n’est pas uniquement technologique : elle est aussi humaine et organisationnelle.
Cette logique collaborative s’étend également aux enjeux de biodiversité. La réduction des collisions avec les cétacés, grâce à des systèmes de signalement et de partage d’observations en temps réel comme Rep-Cet que Marfret a installé sur deux de ses navires, montre que la performance environnementale peut aussi se traduire par une meilleure cohabitation entre navigation commerciale et écosystèmes marins.
The success of this action plan relies on collaboration: engineers, fleet managers, captains, technology providers and maritime experts work together to adapt solutions to operational realities. Maritime innovation is not only technological; it is also human and organizational.
This collaborative approach also extends to biodiversity challenges. Reducing collisions with cetaceans, thanks to reporting and real-time observation-sharing systems such as Rep-Cet, which Marfret has installed on two of its vessels, shows that environmental performance can also mean better coexistence between commercial navigation and marine ecosystems.
Measuring to steer and improve
Finally, no decarbonization strategy can be credible without a robust measurement framework. Daily monitoring of fuel consumption, annual evaluation of the company’s carbon footprint (Bilan Carbone), and independent certification processes such as EcoVadis enable long-term management of actions, objective assessment of progress, and investment decisions focused on the most impactful levers.
Experience shows that by focusing on the core of maritime activity, propulsion, vessel operations and operational decision-making, it is possible to achieve significant emission reductions while strengthening economic resilience and stakeholder confidence.
Towards a credible and responsible maritime transition
The decarbonization of maritime transport relies on a series of concrete, measurable and shared decisions rooted in operational realities. By combining operational pragmatism, technological innovation and cooperation among stakeholders, the maritime sector has the necessary levers to drive a credible, progressive and responsible transition.
