From 1910 until 1912, under Captain G. Oellrich, she sailed to harbors on the West Coast of the US (San Diego, Portland, Oregon), in Europe (Hamburg, Rotterdam), Australia (Sydney, Newcastle), and South America (Chile).

"The only commercial square-rigged sailing ships still operating anywhere in the world, in the year 1953, were the Peruvian guano barques: the three-masters Tellus and Maipo, and the four-master Omega'.

On 26 June 1958 she embarked on a voyage from the Pachamac Islands to Huacho, both in the Lima region along the Peruvian coast, with a load of 3,000 tons of guano.

Her captain, Juan Anibal Escobar Hurtado from Callao, was charged with sinking the ship and had his license suspended.

In spite of paying divers to photograph the wreck in order to show that Omega sank due to age and poor maintenance, he was never cleared and died six years after the sinking, on 16 August 1964.
