CTPETRO-2006 Project (SISGED) – Modeling and Simulation of a Pipeline Georeferencing System
Description: The geo-referenced position of pipes can be identified by the use of PIGs equipped with an Inertial Navigation Unit. In this type of application, the instrumented PIG is conducted through the pipe and the measure of the sensors (accelerometer, gyroscope, etc) are stored during the displacement. The country does not dominate this technology and the few foreign companies that provide services of inertial pigging hold the entire Brazilian market. The modelling and simulation environment that will be developed will allow establishing several necessary parameters to the specifications of several components of the pipeline georeferencing system, such as: required accuracy of the inertial sensors, characteristic of the markers system,constructive information of pipes to be considered to the improvement of the precision of the estimation of its trajectory, filtering methods more suitable to the specific processing of the data of the sensors of inertial PIG, among others.
