During 1997-2004 the research and development activity of S.N.T.G.N. TRANSGAZ S.A. was mainly developed through the Research and Design Subsidiary for Natural Gas Transmission Mediaş.
Taking into consideration the USD denominated amounts, an increase in the volume of the aggregate activity by 36% during 2001 – 2004 compared to 1997 – 2000 registered. Such increase is due to the development of the research and development activities, respectively the increase in the research activity by 42% and of the design activity by 31%.
Concerning the research activity an increase by 62% in the financing share of TRANSGAZ own sources occurs.
Following the research activity developed during 1997-2004, a series of products have been assimilated, as follows:
