A high level of requirements for structural cold-resistant steels is provided by controlling their structure and properties at every process stage. Development of oil and gas deposits in Siberia, in the Far East, in the arctic shelf of the northern seas and establishment of infrastructure of Northern areas calls for the necessity of applying cold-resistant steels with various strength characteristics levels for fabricated structures, which include: marine oil producing and exploration drilling platforms, arctic service vessels, ice-breakers, tankers, deep-water equipment for platform service, hoisting equipment, reservoirs, cisterns, maritime terminals, pontoons, etc.
