**Tandanor** (an acronym for **Talleres Navales Dársena Norte**, Naval Workshops North Dock) is an [Argentine](/source/Argentina) [shipyard](/source/Shipyard) located south of [Buenos Aires port](/source/Port_of_Buenos_Aires), which, together with Almirante Storni yard constitutes CINAR (Argentina's Industrial and Naval Compound) dedicated to [shipbuilding](/source/Shipbuilding) and ship repair.[2]

The port now accommodates vessels from around the globe owing to its international prominence. Its competitive advantage springs from its [Syncrolift](/source/Syncrolift): a ship lifting platform that allows vessels to be [dry docked](/source/Dry_docked) and perform simultaneous repairs on its six slipways. In April 2019, Tandanor signed a cooperation agreement with City Bank.[3]

## History

The company was established as "Talleres Navales de Marina" on November 10, 1879, during the presidency of [Nicolás Avellaneda](/source/Nicol%C3%A1s_Avellaneda) for the maintenance of [Navy of Argentina](/source/Navy_of_Argentina) ships. In 1922, it was renamed "Arsenal Naval Buenos Aires", then establishing as a "sociedad anónima" under its current denomination, with majority of state-capital injection in 1971.[4]

The recently formed S.A. was created in order to supply the merchant fleet and assist with maintenance tasks. It was directed by the Argentine Navy and the National Ports Administration together. The company added workships and two docks to its operational base.

By 1943, Tandanor had more than 6,000 specialised workers. The increased demand of engineers resulted in the creation of the career of Naval Engineering, established by the [University of Buenos Aires](/source/University_of_Buenos_Aires) in 1950, as well as several training programs were also established. During those times the [ARA Libertad](/source/ARA_Libertad_(Q-2)) frigate was constructed as a school ship of the Navy.

In 1973, the Navy sent personnel of TARENA (another shipyard) to work at Tandanor, also giving it new facilities. By those times the company had eight docks and needed to expand its business due to the increasing activity at the Atlantic Ocean. Five years later, Pearlson Engineering of Miami, US, was commissioned to build an elevator "[Syncrolift](/source/Syncrolift)". Tandanor was [privatised](/source/Privatization) in 1991 as part of the economy politics of then president [Carlos Menem](/source/Carlos_Menem). The company was declared bankrupt in 1999.[5]

The company was [nationalised](/source/Nationalization) through a decree by president [Néstor Kirchner](/source/N%C3%A9stor_Kirchner) in March 2007, declaring null all the previous process.[6] As retribution to their efforts to carry out the company during last years, workers of Tandanor received 10% of the company, leaving the 90% as state-owned.[7]
