COASA

What COASA does

COASA (Construcciones Occidental de Andalucía S.A.) is a privately held Spanish Sociedad Anónima founded in 1990 by a group of metal-sector workers, headquartered in the Zona Franca of Cádiz. The company operates as a specialized auxiliary services provider to shipyards and industrial operators in the Bay of Cádiz, with 300+ professionals and immediate geographic mobility across 17 cities. COASA's core business is executing the non-shipbuilding portions of vessel repair, maintenance, and transformation projects at major shipyards — primarily Navantia's facilities in Cádiz, Puerto Real, and San Fernando (Bazán) — and serving cruise lines, naval operators, and ferry companies that bring vessels to those yards.

The company delivers two service lines. The Naval Sector line covers berthing and mooring, crane operations, Layher scaffolding, hull and tank cleaning, heavy piece maneuvers (rudders, propeller shafts, bow thrusters), logistics and material warehousing, boilermaking, welding, piping, and waste management compliant with MARPOL. The Industrial Sector line covers supply, maintenance, and repair of hydraulic and pneumatic machinery, pipe fabrication, pre-commissioning and commissioning of mechanical assemblies, on-site technical assistance, and general industrial maintenance. Notable executed projects include propeller lifts on Royal Caribbean's Harmony of the Seas and Icon of the Seas, mast and funnel work on Carnival and Windstar vessels, propeller repairs for Cunard's Queen Victoria, and steel/welding work on Saudi Navy corvettes built at Navantia Bazán.

COASA operates a project-based B2B model with quote-driven pricing, no publicly disclosed rates, and no proprietary software products. Revenue comes from professional service contracts tied to vessel dry-dockings and shipyard maintenance campaigns. Customer acquisition is primarily through direct relationships with Navantia and through subcontracting pipelines from cruise operators, defense clients (Spanish Navy, Saudi Navy), and regional authorities. The company is integrated management certified (ISO 9001, ISO 14001, ISO 45001 valid through 2028), a member of the IAN industry association and FEMCA federation, and was recognized as Cádiz SME of the Year in 2020. No funding rounds, acquisitions, or public listing activity is disclosed.
