Operations Sous-marines Speciales, widely recognized within the regional maritime industry by its acronym OSS, serves as a prominent provider of underwater engineering and ship maintenance services based in the Kingdom of Morocco. Founded in 1987, the company has cultivated a decades-long history of supporting the commercial shipping and offshore sectors along the North African coast. With its headquarters located in Mohammedia, near the industrial hub of Casablanca, the organization maintains a mobile operational capability that covers all major Moroccan ports, including the strategic terminals of Tangier Med, Jorf Lasfar, Safi, and Agadir.
The company’s primary mission revolves around ensuring the operational readiness of merchant vessels through specialized in-water interventions. It deploys teams of certified commercial divers to execute essential maintenance tasks that eliminate the need for costly and disruptive dry-docking. A significant portion of its workload involves hydraulic hull cleaning and propeller polishing, processes that remove marine biofouling to restore hydrodynamic efficiency and reduce fuel consumption for cargo ships and tankers. Additionally, the company conducts rigorous underwater inspections using advanced video and photographic systems, providing detailed assessments of hull plating, rudders, and propulsion systems often required by classification societies for regulatory compliance.
Beyond its work with floating assets, Operations Sous-marines Speciales is deeply integrated into the region’s port infrastructure sector. The entity is responsible for the installation and maintenance of critical docking equipment, including high-durability fenders and mooring bollards necessary for safe berthing operations. Its technical scope also encompasses the deployment and servicing of marine navigational aids, such as signaling buoys and beacons, which secure coastal navigation channels. Furthermore, the company possesses the heavy equipment and expertise required for complex underwater construction, dredging support, and emergency salvage operations, including wreck removal and underwater welding. By offering this comprehensive suite of subsea and surface solutions, Operations Sous-marines Speciales acts as a vital support mechanism for the maritime logistics chain, facilitating the smooth flow of international trade through Moroccan waters while adhering to strict safety and technical standards.
