Vladimir Ignatyuk (icebreaker)
icebreaker built in 1983
Vladimir Ignatyuk (Russian: Владимир Игнатюк) is a Russian icebreaking anchor handling tug supply vessel. She was built by Burrard-Yarrows Corporation in Canada in 1983 as Kalvik as part of an Arctic drilling system developed by BeauDril, the drilling subsidiary of Gulf Canada Resources. After the offshore oil exploration in the Beaufort Sea ended in the early 1990s, she was sold to the Canadian shipping company Fednav in 1997 and renamed Arctic Kalvik. In 2003, she was purchased by Murmansk Shipping Company and transferred to Russia.
Vladimir Ignatyuk has a sister ship, CCGS Terry Fox, which is operated by the Canadian Coast Guard.
Development and construction
In the mid-1970s, Gulf Canada Resources began developing an Arctic drilling system consisting of two mobile drilling units: a Mobile Arctic Caisson (MAC) that could be submerged and filled with gravel to form an artificial drilling island in waters up to 40 metres (130 ft) in depth and a floating Conical Drilling Unit (CDU) designed for drilling in water depths between 40 and 60 metres (130 and 200 ft) while afloat. The intention of this development was to overcome the relatively short operating window of drillships during the ice-free season (100 to 110 days a year) and the water depth limitations of artificial dredged islands in the Canadian part of the Beaufort Sea. The drilling units, each capable of completing one exploration well per year, would be supported by four Arctic Class 4 vessels: two large icebreakers providing 24-hour ice management and standby services on the drilling site and two smaller icebreaking vessels responsible for anchor handling and supply runs between the drilling rigs and coastal bases. By 1982, both drilling units and all four icebreaking vessels were under construction in Canada and Japan for BeauDril, Gulf Canada's drilling subsidiary, and the company had committed itself to a billion-dollar exploration program between 1983 and 1988.
The icebreaker design was provided by the Montreal-based engineering company German & Milne.
This brief starts where responsible research should: with the source description of “Vladimir Ignatyuk (icebreaker)” as icebreaker built in 1983. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as icebreaker built in 1983. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Mar 1, 2026. The linked authority identifier is Q130379. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1983, 1997, 2003 and 1982.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
