ATEC operates in the naval and industrial sectors where technical expertise, regulatory requirements and responsiveness are essential. Specialists in boiler making, piping and welding, we support yachts, naval vessels, commercial ships and industrial sites with tailor-made solutions designed and built by our teams of experts.
Our strategic location in Marseille means we can respond quickly throughout the South of France, whether for planned or emergency work. Find out more about our main areas of activity and the tailor-made services we offer.




Yachts & pleasure boats: tailor-made excellence
The yacht and pleasure boat sector requires particularly specialised know-how. Our teams regularly work with shipyards specialising in the maintenance and renovation of luxury yachts and top-of-the-range pleasure craft.
ATEC carries out a wide range of work to modify, repair or improve the structure of yachts and pleasure boats. This includes, among other things, the integration of new mechanical equipment (bow thrusters, stabilisers, stern tubes), the transformation of the hull for aesthetic reasons, as well as numerous operations to bring it up to standard in the face of corrosion or wear and tear (replacement of corroded or weakened hull sections, repair or reconstruction of bilges and tanks affected by corrosion, upgrading of metal structures to ensure compliance with classification society standards, rework of non-compliant welds, etc.).
We also manufacture a wide range of customised metal parts, including tanks, mechanical supports, metal furniture, anchor pockets and mirror-polished stainless steel structures, as well as a host of other products entirely tailored to the specific needs of each project.
All work on yachts and pleasure boats is carried out with the utmost care, in line with the high standards of in-season lead times, quality, safety, cleanliness and protection of the yard – essential criteria for owners and operators.

Military boats: know-how at the service of defence
In the military sector, high standards are the norm: every intervention must meet rigorous standards of security, confidentiality and performance. We support naval defence contractors in the renovation and maintenance of their boats in compliance with military protocols.
Our expertise in sensitive contexts guarantees controlled operations that meet the technical expectations of the sector. Located close to the major military ports in the south of France, we are also able to respond quickly to urgent requests




Industrial sites: proven technical expertise
Industrial sites, whatever their sector, require high-performance, reliable technical solutions to guarantee the long-term future of their facilities. ATEC works with industrial companies to carry out boiler-making and piping work that meets the most stringent requirements, whether for the construction, maintenance or modernisation of infrastructures.
We specialise in the manufacture and installation of metal structures (tanks, vats, supports for heavy equipment, piping supports, platforms, etc.), the creation of high-pressure piping networks, and the integration of customised solutions for industrial fluid systems.
Our teams have the expertise to repair and replace faulty or obsolete components, ensuring optimum safety and reducing operational risks. Whether the work is planned or urgent, we make it a point of honour to meet production deadlines and ensure rigorous monitoring of every stage of the project.
We design tailor-made solutions that take into account the specific features of your installations, while optimising costs and response times. This process enables us to minimise production stoppages and improve the overall profitability of your industrial facilities.
