Talleres Navales Argentinos

What Talleres Navales Argentinos does

Talleres Navales Argentinos S.A. (TNA) is a privately held Argentine industrial services company headquartered in Dock Sud, Buenos Aires, founded in the early 1980s and operating with 51–100 employees. The company delivers maintenance, construction, modification, repair, and modernization services across six core service lines: Motors (diesel industrial, marine and stationary engines), Calderas e Intercambiadores (boilers up to 50 tons/hour and heat exchangers), Calderería-Herrería (pressure vessels, tanks, structural metalwork), Piping (1/2 to 30-inch lines for water, hydrocarbons, chemicals, steam and cryogenics), Raschinaje (sandblasting, coatings, tank cleaning), and Servicios Generales (thermal insulation, IRAM-certified scaffolding, electricity, automation, hydraulics-pneumatics, machining, refrigeration). Work is performed in the company's workshop or on-site at client facilities and aboard vessels, supported by certified non-destructive testing and an in-house metrology laboratory with controlled atmosphere calibration.

The business is B2B and project-based, with quote-driven pricing reflecting the scope, materials, and labor intensity of each engagement. Customers span the Argentine Navy, Prefectura Naval Argentina, port operators, grain terminals, municipalities, and industrial contractors, with services delivered regionally in Argentina and dispatched internationally for vessel work via personnel holding boarding credentials and passports. Regulatory credentials — particularly Prefectura Naval Argentina approval and Lloyd's Register of Shipping audited welder procedures — define the addressable market and act as a meaningful barrier to entry.

Revenue mechanics are typical of mid-sized industrial services firms: recurring maintenance contracts with industrial accounts, episodic project work for marine engine overhauls and boiler retubing, and on-call repair services. The company is led by President Miguel Doallo, operates no parent or subsidiary structure, and has no disclosed external investors or funding history. Quality assurance is anchored in an implemented quality management system and certified inspection outputs, with no disclosed digital, AI, or software-based service components.
