Wikipedia states that "Although initially classified by Bureau Veritas and flying the Dutch flag, the ships were reclassified by the Russian Maritime Register of Shipping and their port of registry was changed to Aktau, Kazakhstan, shortly after delivery. Following the discovery of the Kashagan Field in July 2000, Arcticaborg and Antarcticaborg have since been operating for Agip KCO in the Northern Caspian Sea, where the water depth is only 4–7 metres (13–23 ft) and the ice conditions are particularly difficult.[10] In 2000 dedicated ice-strengthened barges, pushed or towed by the icebreaking supply ships, were developed and constructed to allow uninterrupted cargo transportation to and from the platforms year round. In May 2017, Royal Wagenborg was awarded a five-year contract for icebreaking and other services in the Canadian Arctic. The company will relocate Arcticaborg from the Caspian Sea to Vancouver via the Panama Canal."

The company relocated Arcticaborg from the Caspian Sea to Vancouver via the Northwest Passage.[13][14] The ownership of Arcticaborg was retained by Wagenborg; the vessel is on a bareboat charter to Fathom Offshore. In August 2019, Arcticaborg left Canada for a two-year contract in Russia. As of 2020, the vessel is operated by Mercury Sakhalin in the Sakhalin oil fields under the Russian flag."
