1. High-quality cold-resistant steel was produced in Russia.

2. In large industrial scales cold-resistant steel welding technology was

developed.

3. The Project allowed to carry out plant radical modernization and provided

support and staff preservation during the most severe 1990’s.

4. Cooperation with foreign Designers allowed to assimilate the advanced

design methods.

5. Unique experience with large number of contractors including the foreign

contractors is received.

6. Technology of afloat structures assembly nearly any dimensions using

underwater welding is developed and assimilated.

7. The extensive offshore experience in the Arctic conditions is received.

8. Uniformity of design supervision approaches is necessary.

9. Design institute for the shelf development of the Russian Federation is

necessary to create.
