Sud Moteurs Groupe

What Sud Moteurs Groupe does

Sud Moteurs Groupe is a French privately-held marine engine and propulsion maintenance, repair, and overhaul (MRO) services provider founded in 1994 and headquartered in Marseille. Operating as a SASU (single-member simplified joint-stock company) with approximately 100 employees, the company services diesel and gas engines, reverse/reduction gearboxes, turbochargers, speed governors, and full propulsion lines for marine and industrial customers. Its technical scope spans multi-brand expertise across MAN, PIELSTICK, ABC, CATERPILLAR, WARTSILA, MAK, CUMMINS, and SULZER engines, with REINTJES and MASSON gearboxes and SCHOTTEL propulsion systems, delivered through both workshop-based overhauls and on-site mobile machining and laser alignment services.

The company operates from six sites: a flagship 8,000 m² workshop in Marseille with 30-ton lifting capacity, regional workshops in La Seyne-sur-Mer, La Ciotat, and Brest (1,500 m², ISO 9001 certified), and overseas facilities at Fort-de-France (Martinique) and Le Port (La Réunion), enabling coverage across the Mediterranean, Atlantic, Caribbean, and Indian Ocean. Revenue is generated through professional services (engine and propulsion MRO, technical engineering and design) and hardware sales (OEM spare parts, governors, filtration, couplings, separators, coolants), with custom-quoted engagement scoped to each customer's vessel or installation. Pricing is not publicly disclosed.

Sud Moteurs serves four primary verticals — commercial marine shipping, military navy, yachting, and power generation/industry — with a customer base that includes CMA CGM, La Méridionale, GNV, CTN, ENTMV, DFDS, the French Military Navy, Equans, KOHLER SDMO, EDF, and Petroineos. Go-to-market is direct enterprise field sales with on-site service delivery rather than intermediary channels, and the company holds ISO 9001 quality certification and RINA classification society approval at its primary sites. There is no external investment, parent company, or public listing; ownership appears to be founder-controlled with no recorded M&A, fundraising, or leadership change activity in the available data.
