Pipelines, installed in all soil and environmental conditions on behalf of the major Oil & Gas Companies, represent the evidence of Impresa Tre Colli construction capabilities and reliability. The continuous improvement of operating methodologies as well as the research for new fabricating solutions allows Impresa Tre Colli to carry out the installation of large-diameter pipes in the most different conditions, such as the installation of a large number of pipes inside a micro tunnel, directional drilling, river crossing etc.

The experience gained in very complex projects such as the Oil piping connecting Genova Multedo oil terminal and Genova Pegli oil deposit, consolidate Impresa Tre Colli as one of the major experts in micro tunneling.
