In the early 20th century, whaling began to be conducted with modern techniques
developed in Norway. For this purpose, whaling companies were formed in
Valdivia,
Chiloé and
Punta Arenas. Andresen's 1907 catch of 79 right whales drew competition to the area, though the success went unmatched. In 1914, he set out from San Pedro with a factory ship,
Sobraon, and two catchers to hunt humpbacks along the coast from Chile, Peru, Ecuador and on to Columbia, following the migrating animals. Andresen was the first person to raise the Chilean flag on Antarctica. However, his whaling business ultimately failed as a result of economic depression and the collapsing world market for whale oil. Encouraged by Andresen, another Norwegian whaler, Christen Christensen, sent the
Vesterlide to San Pedro, captained by his own son, to hunt blue whales in the Bay of Corcovado. Christensen also financially backed another whaling company, Sociedad Ballenera y Pescadora, which was operated by H.C. Korsholm in
Valdivia. Unfortunately, the returns were inadequate and both companies were liquidated by 1913. ==References==
