What Tandanor does
TANDANOR (Talleres Navales Dársena Norte S.A.C.I. y N.) is an Argentine state-owned shipyard and industrial complex founded on November 10, 1879, re-nationalized in 2007 under Decree 315 with 90% ownership held by the Ministry of Defense. The company operates under the CINAR (Complejo Industrial Naval Argentino) brand and runs two principal facilities: the main TANDANOR yard in Dársena Norte, Buenos Aires, featuring a Syncrolift elevation system and four drydocks measuring 220, 178, 149, and 149 meters, and the Talleres Almirante Storni workshops at Puerto Belgrano Naval Base with 33,000 m2 of covered area and 15,000 tons/year sheet metal processing capacity.
TANDANOR delivers three core service lines: ship repair and maintenance (for commercial tankers, container ships, fishing vessels, and naval ships), new vessel construction (including the ARA Pampero tugboat, ARA Petrel SWATH hydrographic vessel, and Tracker aluminum patrol boats), and large-scale metalworking for the oil, gas, energy, and rail infrastructure sectors. The facility services 120+ vessels annually from international shipowners and holds classification certifications from DNV, Lloyd's Register, NKK, and the Argentine Maritime Authority (PNA). Notable major projects include the ARA Almirante Irízar icebreaker refurbishment and modular construction of the Base Antártica Conjunta Petrel.
The business model is project-based B2B services revenue (repair contracts, vessel construction contracts, and metalworking fabrication contracts), with no public pricing tiers disclosed. Go-to-market relies on direct enterprise relationships, government procurement through the Ministry of Defense, and industry event participation. The customer base is anchored by the Argentine Navy (Armada Argentina), federal agencies (COCOANTAR, Servicio de Hidrografía Naval, Parques Nacionales), and recurring commercial shipping and fishing fleet clients. The company executed a voluntary retirement plan from June 30 to December 31, 2024, suggesting active workforce restructuring alongside continued operational execution through 2026.
