Miscaroo was an icebreaking anchor handling tug supply vessel built by Vancouver Shipyards for BeauDril, the drilling subsidiary of Gulf Canada Resources, in 1983. She was part of a fleet of Canadian icebreakers used to support offshore oil exploration in the Beaufort Sea. In the 1990s, the vessel was acquired by Canadian Marine Drilling (Canmar) and renamed Canmar Miscaroo. In 1998, she was purchased by Smit International and served in the Sakhalin oil fields as Smit Sakhalin until 2017 when the 34-year-old icebreaker was sold for scrapping in China.
