The eco-energy transition in the field of maritime transport

The decarbonization of maritime transport or how to reconcile energy sobriety and economic performance?

While maritime transport accounts for about 3% of global CO2 emissions and could account for 17% by 2050*, many projects are being developed to decarbonize this mode of transport. HVAC (Heating, Ventilation and Air Conditioning) equipment and refrigeration systems are the leading source of energy consumption on land and the second largest at sea after propulsion on board ships.

AXIMA Marine, an entity of the EQUANS group, works for the naval, civil and military industries. It designs, builds and maintains HVAC and refrigeration solutions that play a major role in the decarbonization of maritime transport. AXIMA Marine is a specialist in HVAC and refrigeration, as well as fire safety for all types of ships, with over 140 years of experience in the field.

Thanks to its leading position, AXIMA Marine's teams support major shipbuilding companies in their international projects, and also have offices around the world. These teams, passionate about the maritime world and aware of the crucial issues surrounding global warming, are very involved in the development of new technologies and products that are more environmentally friendly.

How to decarbonize maritime transport?

  • Speed

    Limit sea veteran speed* (33% of the fleet).
    *Slow steaming : "A 12% reduction in average forward speed leads to a 27% decrease in daily fuel consumption and therefore to lower GHG emissions".

  • Optimize ships

    Shore connection; Smoke filtration systems ("scrubbers") or water treatment; smart steering; waste heat recovery.

Inventing sustainable, low-carbon maritime transport

From the design phase called "Eco-design", AXIMA Marine offers its customers equipment and services that combine energy consumption control, technical feasibility and customer needs.

From eco-design to energy efficiency audits, to the design and operation of low-carbon HVAC and refrigeration solutions for ships, AXIMA Marine has a wide range of expertise that gives it great legitimacy.

Its expert refrigeration teams develop refrigeration solutions using natural and low-carbon refrigerants. In addition, our innovative test facilities, climatic test bench, allow our teams to test and qualify all our developments.
