Group history

Ultranav was founded as Sociedad Naviera Ultragas Ltda. in 1960 by Captain Albert von Appen (1901-1971), who arrived to Chile from Hamburg in 1937 as a representative for the Hapag and Norddeutscher Lloyd shipping companies. The company was amongst the first to be engaged in the transport of gas in liquid form having constructed as its first vessel, the “Ultragas“, a 90 cubic meter capacity gas carrier newbuilding. With an overall length of 23 meters, it was probably the smallest vessel of its kind ever built. Placed into service in the southern-most Patagonia region of South America, it vastly improved the logistics for local gas producers and consumers, replacing the traditional transport of gas in steel bottles.

Captain von Appen was subsequently joined by his two sons, Sven von Appen and Wolf von Appen, who successfully developed and diversified the company. Ultranav initiated the expansion of its businesses and continued strengthening its position initially in Chile, later in Latin America and finally reaching a global level through different trades and segments. This growth has come in the form of different companies where Ultranav has developed its roles as owner, charterer and operator of merchant vessels spanning a broad spectrum of fleets specialised in international and cabotage maritime transport.

In deep sea shipping activities Ultranav today operates and owns tankers for the transport of crude oil, refined products, and chemicals; dry cargo bulk carriers, multi-purpose dry cargo and container vessels, as well as specialised vessels for the transport of liquefied gases. Because of this broad diversification in different segments the company changed its name to Naviera Ultranav to better integrate its different businesses and subsidiaries. Since 2012 Ultranav provides its services through its twelve divisions Ultrabulk, Navigator Gas, Ultratank, Cape Tankers, Austral Product Tankers, Horizon Shipping, Ultranav Chile, Antares Naviera, Naviera Transoceánica, International Shipowning, Ultratug and Wilson Sons UltraTug offshore.

The company is today led by Per von Appen, the third generation of the von Appen family, as Chairman of the Ultranav Advisory Board. Per Succeeded his brother, Dag von Appen, who had served as Chairman for about 20 years.
