These years are usually named “perestroika” period. USSR's disintegration into independent states, economics conversion to market relations drastically changed the situation in oil industry.
Within first five years of “perestroika” crude oil output drastically dropped, theoretic research works were practically scaled down, design & survey works were mainly for rehabilitation of some oil field facilities, exploration and wells drilling was practically stopped.
Hardships of this period (1990-2000) did not bypass Giprovostokneft as well. Work scopes noticeably reduced, especially researches, staff gradually decreased.
But GIPVN withstood and saved its potential and basic manpower.
It was the great victory of the Institute people. Without doubt GIPVN management, its Director B. Usachev played the decisive role in the said. Due to his immense prestige among GIPVN people, links with oil producing companies and business partners GIPVN did not lose main clients; it has work and was able to pay salary practically without delay.
Since latter half of 90th the situation began to recover step-by-step. Stagnation period in oil industry was going to the end. Significant changes appeared in GIPVN activities: emphasis moved to development of oil & gas products trunk pipelines, development of oil & gas bearing areas in East Siberia, Far East, north of European part, offshore fields.
In this period great support for GIPVN, which in principle settled its economic problems, was awarded contract for design engineering (together with foreign partners) of Caspian Pipeline System Tengiz – Novorossiysk.
This Project was the school of engineering based on international standards and the work noticeably improved GIPVN reputation at design engineering market, including the foreign one.
Since 2000 till present day scope and range of design & survey and research works steadily increase. GIPVN with confidence gathers pace, plays active role at R & D market.
