[2][3] The new shipping company was intended to promote the economic development of Sakhalin, which Russian had recently acquired from Japan.

By 1951, the company's fleet had grown to 30 vessels and transported 2 million tons of cargo from Vladivostok to Sakhalin and other ports along the Sea of Okhotsk.

In 2021 SASCO transported equipment from Vladivostok to Novatek natural gas projects on the Taimyr peninsula.

Specifically, SASCO was sanctioned for its role in providing logistical support to future energy projects in the Russian Arctic, particularly those in the Taimyr Peninsula.

[10] On 16 October 2014, the SASCO-owned MV Simushir lost power off Haida Gwaii, also known as the Queen Charlotte Islands, along British Columbia's coast as it made its way from Everett, Washington, US, to Russia.

The Canadian Forces' Joint Rescue Co-ordination Centre said the large oceangoing tugboat Barbara Foss arrived on 18 October to the tow of the Simushir.
