Maritime Signaling in Algeria (1962–1971)

The history of the ONSM is deeply rooted in the modernization of national infrastructure following Algeria’s independence. Indeed, the management of coastal navigational aids has undergone profound institutional transformations since 1962 to ensure safety of navigation at sea.

Evolution of Maritime Signaling in Algeria (1962–1971)

Following independence, the state had to fully reorganize the vessel buoyage and guidance network. This reorganization took place across two major transitional phases.
Historique de l'ONSM

From 1962 to 1967: Decentralized Management by Subdivisions

Until July 1967, three specialized subdivisions managed the buoyage and signaling along the Algerian coastline. These local structures reported directly to the departmental directors of maritime services in Oran, Algiers, and Annaba.

In practice, each subdivision exercised technical oversight over signaling facilities located respectively in Oran, Algiers, and Constantine regions. Consequently, the respective departmental directorates were responsible for technical personnel, maintenance staff, and buoyage assets.

From 1967 to 1971: Toward Centralized Maritime Services

The state took its first step toward unification in July 1967 with Decree No. 67-121. Promulgated under the authority of the Ministry of Public Works, this text established a national Maritime Signaling Service based in Algiers.

From then on, this new centralized structure comprised:

  • A central administrative service.
  • An operations and control subdivision.
  • A study and engineering subdivision with a central warehouse.
  • Three regional operations and control sections.

Nevertheless, an administrative duality persisted in the field, as the various Infrastructure and Equipment Directorates (DIE) along the Algerian coast continued to manage personnel and equipment locally.

The Administrative Reform of 1971: A Strategic Turning Point

To resolve the inefficiencies of this dual management model, the government issued Decree No. 71-68 on March 9, 1971. This legal decree placed all maritime signaling under the sole authority of the service’s Chief Engineer.

As a result, this landmark reform made it possible to:

  • Permanently clarify the institution’s responsibilities.
  • Unify the management of all human and material resources across the coastline.
  • Enhance the efficiency and responsiveness of buoyage operations along the coast.

Since this pivotal turning point, centralized management has streamlined day-to-day operations and greatly facilitated the integration of modern technologies required for ONSM’s ongoing missions. This rich journey defines ONSM’s legacy as a cornerstone of national maritime safety.
