32. High-quality cold-resistant steel was produced in Russia. • In large industrial scales cold-resistant steel welding technology was developed. • The Project allowed to carry out plant radical modernization and provided support and staff preservation during the most severe 1990’s. • Cooperation with foreign Designers allowed to assimilate the advanced design methods. • Unique experience with large number of contractors including the foreign contractors is received. • Technology of afloat structures assembly nearly any dimensions using underwater welding is developed and assimilated. • The extensive offshore experience in the Arctic conditions is received. • Uniformity of design supervision approaches is necessary. • Design institute for the shelf development of the Russian Federation is necessary to create.
