Interview – Marineec Technologies: decarbonisation at sea starts with good energy management

You joined MARINELEC Technologies in the fall to develop the potential of energy management systems. What motivated you?

[Aurélie Cordelle] I am an engineer by training and have worked as a technician in the aeronautical sector for over 10 years, particularly in the development of digital solutions in this sector. This experience made me question its finality and I decided to leave this sector, which did not seem to me to be virtuous enough from an ecological point of view. I joined a wind turbine development company in Great Western and found a true vocation, continuing to dedicate myself to the decarbonization of the marine industry.

When the opportunity to join MARINELEC Technologies arose, I was immediately excited when the project was presented to me. Firstly because I find it relevant to work on decarbonisation issues, but also because the energy management approach is a topic that really speaks to me. We live in an increasingly connected and insanely fast-paced world. Data acquisition and analysis are key elements that allow us to understand, assimilate and find solutions to reduce our consumption.

I was also motivated by the idea of ​​starting with a product with strong growth potential and, above all, a product that meets real customer needs and challenges. It’s hard to find the right balance with a product that can be brought to market very quickly and developed enough to respond quickly to challenges. Reducing consumption is as important in terms of operating costs as it is in terms of reducing greenhouse gases, and ECOMER meets both challenges.

What are the main findings and analyzes of MARINELEC on which the development of ECOMER is based? (issues, rules, recommendations)

[Aurélie Cordelle] To meet the Paris Agreement, the IMO has set a target of reducing GHG emissions by 40% by 2030 and 70% by 2050. There are 3 main levers for this: control, reporting and optimization. The ECOMER product is the main element of the first “management” arm, which allows you to understand your consumption, but also guides you to more virtuous use and management. It is also an accelerator in the third “optimization” lever: ECOMER-equipped ships have more and more technologies that tend to reduce GHG emissions, which will be immediate to measure but also to optimize different solutions. ship performance.

The observation occurs especially when we discuss with our customers: they know that it is important to reduce consumption, they know that there are elements to consider, but they do not have accurate information to make decisions and act. For example, slow down yes, but how much? Seafarers have qualitative knowledge, ECOMER provides quantitative data. With ECOMER, they will know what the optimal consumption rate will be and adjust accordingly. They will also know that some actions have more impact than others.

Monitoring, reporting and optimization is the technical answer to Ademe’s thoughts. MARINELEC is an excellent player in the sector, which is very well versed in marine electronic equipment, allowing us to invent a technical solution that meets the need defined by this collective reflection involving sailors, the energy agency and industrialists. One of the strengths of our approach is to offer use cases for our solutions tailored to the needs of each maritime transport sector thanks to data already collected and interpreted over the 5 years of product existence.

Who is ECOMER aimed at? (customers, markets)

[Aurélie Cordelle] This applies to all segments of the maritime industry, especially work, service, fishing and transport vessels. It is intended for both ship owners and charterers. The main objective is to reduce consumption, but this also includes improving the overall performance of the vessels. And above all, knowing that the issues are not the same, we want to respond to personnel both at sea and on land. As for the market, it affects all maritime sectors, especially service ships, transport and fisheries.

Like other MARINELEC products, ECOMER is intended for both France and export, and it is cautioned that it is not yet a mandatory safety product and is therefore not included in the procurement list at the shipyard. Eventually, it will be able to equip any ship.

How does it work and what are the expected results? (carbon footprint, energy savings, monitoring and decision support, behavioral changes)

[Aurélie Cordelle] ECOMER works on 4 technological bricks:

  1. Data collection on existing sensors or by adding new sensors: mainly flowmeters, GPS, MRU (inertial units).
  2. Data processing and display to the pilot on the bridge through electronic charts or automata developed by MARINELEC to provide targeted and effective decision-making aids for navigation personnel who do not have additional time for data analysis. .
  3. Data transfer and storage in the secure MARINELEC cloud located in Brittany.
  4. Web interface under development, including further processing of data and analysis of results.

This configuration allows to make the first reductions in real-time consumption (decision support), but also to improve the performance of ships, perform predictive maintenance, remove elements of eco-driving, etc. allows you to provide the basic elements for

We estimate that the use of ECOMER can reduce fuel consumption by up to 30% in the best applications, especially for workboats that do not yet have any optimization solutions. This should be compared with new behaviors for sectors where consumption is not a real issue (speed reduction, engine shutdown, electrical load reduction, eco-drive ships).

How will you implement these solutions?

[Aurélie Cordelle] The marine sector fully reflects the environmental transition. If certain solutions, behaviors are already well known, data analysis will allow to find other traces. To do this, we rely on a product that allows us to adapt over the years with the ability to obtain new data and regular software updates to obtain new opportunities to reduce consumption.

When I came to MARINELEC Technologies, I did market research to better understand the challenges and opportunities. I also focused on companies that have implemented similar solutions. There are many companies involved in data analysis; but they do not have the technological expertise of equipment like MARINELEC. By understanding the problems and actors, we can adapt and provide our global solution or complementary bricks, but first we support our customers with use cases and answers tailored to their needs. The climate emergency is concrete. We must proceed today with humility and the realization that we have much to learn and information to gather. They will allow us, for example, to develop artificial intelligence solutions in the future. It is a source of pride for me to bring my expertise in digitizing the sector to the service of the maritime sector and an innovative company committed to decarbonisation.
