Hefty dose of new projects of company depend on basic data fullness and construction of permanent facilities planning accuracy in an early stage. Potentially productive license blocks are characterized by extremely inhomogeneous geology what can lead to problems in engineering process, construction of works and also can lead to period and cost increase for the purpose of inadequate attention on the stage of conceptual engineering. Creating a module for optimal allocation of infrastructures sites and linear facilities routes allows undertake the analysis, look for stable and most effective solution under terminated basic data. In case of appearance new information, it allows recalculate and give a recommendation about necessity of entering of adjustments in previously stated solutions.

Result of current work, as part of engineering design, is prototype module for information system ERA:ISKRA. Analysis and introduction topographical data best practices, and also parallel appliance of cost engineering module, allow develop optimization algorithms, which taking into account both technologic facilities parameters and differences in cost of constructing in diverse terms. Module considers factors such as: terrain relief, hydrologic and topographic special aspects of construction other facilities existent in this zone.

Developed algorithms for finding optimal trajectory allowed discount cost of communications corridors by 10 per cent in comparison with projected manually. Achieved result reached due to: decreasing summary length of net, pipeline placement in most optimal conditions for building (minimization bogs crossing), decreasing pipeline diameters (decreasing summary length of net and the difference in elevation).
