DCNS, a mine of skills: Alexandre, electro-mechanic


Alexandre, an electro-mechanic in the Auxiliaries department in Brest, works on the electric motors of French Navy vessels. An ex-apprentice, he has now in turn become an instructor: a great example of knowledge transmission! He explains to us his high-precision profession.

Alexandre joined DCNS in 2011 as electro-mechanic apprentice. On completing his professional training at the end of 2012, he joined the Rotary machinery (electric motors) team within the Auxiliaries department. Alexandre is now responsible for the maintenance of all electric motors on French Navy submarines and surface vessels. “We are a team of eight electro-mechanics. Most of our work is conducted in the workshop but we can also be requested to go aboard for inspections or repairs.”

In the workshop, the foreman distributes the machines to be verified or repaired as a function of each person’s experience. A motor can require anything between a day’s work or four full weeks, full time, and is variable depending on type. Electro-mechanics work on different types of electric motor, both alternating current and direct current. Installations can be complex and require high-precision work. Once the repairs have been made, the motor is tested on the test platform to validate its proper operation before being re-installed on board. “With experience, anomalies can be diagnosed more rapidly. This year, I am in turn instructing an apprentice: it is a real pleasure to transmit my knowledge.”

“A good electro-mechanic is passionate about technology, is meticulous and of course conscientious”, concludes Alexandre, who plans to further perfect his skills to eventually become an expert in his field.
