Class Summary
This class is designed for people managing pipe transportation (oil, gas …). This class will cover how to manage pipelines in a real 3D GIS and a linear referencing system (LRS). Based on this pipeline referential, we will see how to ensure that we respect security constraints regarding construction around the pipeline using 3D LRS technology. We will also cover pipeline maintenance to illustrate how we can collect data from a yearly inspection and compare it to the previous inspection to enable us to see the evolution of the pipeline and make the right decisions.

Learning Objectives
At the end of this class, you will be able to: Understand 3D LRS system Model a GIS database for pipelines Foresee risks around the pipelines Maintain a pipeline infrastructure

Risks - examples
Pipeline break in a natural reserve in the south of France:

Application goal
Help to generate a risk study. Demonstrate that all necessary measures have been taken to avoid impact on
people and environment Present the exhaustive analysis of all risks associated with the site (or pipe) Help make decisions

Dynamic segmentation in 3D
The only way to manage pipelines and referenced objects, is to use 3D LRS. It allows to calculate the real M address of each object (tube) and obtain his
linear address on the 2D map we are displaying.
First point (address 0): FOS-SUR-MER
Address 1 , Terrain altitude 1, Pipe Altitude 1
Address 2 , Terrain altitude 2, Pipe Altitude 2

The referential

Bulding the referential
Referential is based on the axis and the tubes (elementary element) Acquire data to have the axis information in 3D Get terrain information (DTM) Tubes (information coming from the construction)

Calibrate the referential
Calibrate based on inspection results using a wizard Calibrate using known points
Draw tubes in the map to validate

Implementing an application – the necessary data
© 2011 Autodesk
Necessary data
Land information Parcels and information about owners Orthophotography Addresses Natural risks Road traffic Urban area Buildings (all : building receiving people and capacity and houses …) All information about the pipe which is available Inspection information (inside the pipe itself) this will help evaluating the risk around the pipeline

Necessary data – Building receiving public
Capacity max of the building
Number of employees
