Abstract
Techniques for three-dimensional visualization and simulation of construction are applied in regions where companies install pipes for oil and gas. These regions can present aspects of geological and geotechnical risks, which can compromise the structural integrity of the pipes, by movement of the solids and interaction between soil and pipe. A system capable of evaluate these regions was created based on digitalized data of aerial photographs, coordinates of control instruments and on ground topography. The system consists of a three- dimensional environment (3D) using technics on virtual reality (VR) developed to support the analysis of existing problems. The system is completely geo-referenced, which permits definig adequate solutions for the projects as well as avoiding problems for some specific areas. In addition, the system permits interaction with specialists, enabling them to indicate directly on the 3D images, the risk aspects for further evaluation in situ and for taking adequate decisions.
