The expertise of an electrical machines designer and manufacturer

In a context where energy efficiency has become a critical challenge for the maritime industry, certain players stand out for their ability to innovate and transform operational practices. This is particularly true for a designer and manufacturer of electrical machines, drives, and associated control systems, whose technologies are now equipping a growing number of vessels, particularly in the cruise sector.

Alongside this industrial player, experts are actively involved on-site. This is the case for Romain Poirot, an engineer who has been working on these large-scale projects for several years.

Optimizing onboard energy consumption

Historically, many onboard systems operated in a binary way: either at full power or completely switched off, an approach that lacked flexibility and was highly energy-intensive.

The introduction of power converters has fundamentally changed this paradigm. These systems enable precise modulation of power output based on actual demand, resulting in improved energy management and significant fuel savings.

As Romain Poirot explains:
“Previously, it was either 0 or 100%. Today, we can adjust power according to real needs, which allows for substantial savings.”

Beyond improved usability, this technology represents a tangible lever for reducing operating costs for shipowners, with a rapid return on investment driven by energy savings.

A key expertise in electric propulsion

The expertise of such industrial players goes beyond energy management. It also extends to electric propulsion systems, a strategic area in the maritime energy transition.

Teams — including Romain — are involved in:

• The design and integration of electric motors,
• The commissioning of propulsion systems,
• The maintenance and optimization of existing installations.

These systems enable vessels to operate more efficiently while significantly reducing their environmental footprint.

Technical missions… around the world

One of the most distinctive aspects of these projects is their international scope. Engineers are required to work directly onboard vessels, wherever they are located.

“These assignments take us all over the world, wherever the ships are,” says Romain.

From Australia to Hawaii and the United States, operations take place across all continents, close to where vessels are deployed.

These missions allow teams to:

• Ensure proper commissioning of equipment,
• Guarantee optimal system performance,
• Support local crews in day-to-day operations.

A tangible and measurable impact

Beyond the technology itself, the real differentiator lies in its impact. By enabling precise power regulation and optimizing propulsion systems, these solutions contribute to:

• Significant reductions in fuel consumption,
• Improved overall vessel performance,
• Extended equipment lifespan.

In a rapidly evolving industry, these innovations clearly demonstrate how electrical engineering can effectively address both economic and environmental challenges.
