Vessel Description

OBSERVADOR is a hydrographic and oceanographic research vessel operated by Argentina's Servicio de Hidrografía Naval (SHN), the naval authority responsible for nautical cartography and hydrographic surveying in Argentine waters. Built in 1999 by Fassmer Shipyard in Germany, the vessel is purpose-built for conducting hydrographic surveys, bathymetric data collection, and oceanographic research in support of Argentine nautical chart production and maritime safety. Operating primarily across the South Atlantic and the Argentine continental shelf, OBSERVADOR plays a central role in maintaining and updating hydrographic data for Argentine territorial and jurisdictional waters, including survey operations extending toward the Southern Ocean and Antarctic sector. As an asset of the Armada Argentina, the vessel conducts missions aligned with national maritime sovereignty and scientific research mandates.
