1. The document discusses Petrobras, a large Brazilian energy company, and its Geodesy Department which handles positioning and mapping. 2. It specifically focuses on the SGO system, an internal CAD-based system used to manage subsea pipelines and equipment, and an ETL process that extracts, transforms and loads this data into a GIS database for improved querying and analysis capabilities. 3. This ETL process handles over 130 rules to properly transform each element type according to engineering rules and load it into a customized Oracle Spatial database, taking over 3 hours to run daily to keep the database updated.

5. SGO
! SGO is a system developed to process, store and
share data related to subsea pipelines,
equipments and platforms installed by Petrobras.
! Used for planing and safe execution of all offshore
operations, avoiding accidents in facilities and
reflexes for people and enviroment.
! Is CAD based – Started in 1995 (MicroStation).
! 18.500 access in May 2014.
! Users in more than 300 vessels.

8. ETL
! Why ETL?
• Create GIS tools in CAD (Queries, Searchs,
Attributes, Topology...) is an arduous task;
• Keep a CAD based structure updated every day (44
dgn files in Campos Basin – 8 professionals);
• Backup in DVDs;
• More than one UTM zone;
• Build a structure to GIS systems;
• Data Validation (Geometry, Topology, attributes);
• Interoperability;
• Good data to build good solutions;
• Have more than visualization.

9. ETL
! What does the ETL do?
• Extracts data from CAD;
• Transform them, doing all validations and creating
geometries according to each element behavior;
• Loads them into a customized APDM (ArcGIS
Pipeline Data Model – World Standar) Oracle
Spatial Database.

10. ETL

11. ETL
! Requirements
• Treat each element (46) separately according to
the engineering and connectivity rules (Anchors,
Anchor Lines, Pipelines, Platforms, WCTs,
Manifolds, Connectors...);
• Treat Cell elements;
• Improve security;
• Remove Microlines;
• Update the Database every day;
• Leave nothing behind;
• Keep removed features (history);
• Report the errors.

12. ETL
! Around 130 rules;
! Some Rules:
• A regular Anchor connects to an Anchor Line;
• A regular connector is suppose to have at least two
pieces of pipelines;
• A WCT has always to be in a well head;
• A PLET always connects a steel pipeline to a flexible
one;
• There are no lines with less than 1 meter of length;
• Cathodic Protection, in SGO, just in steel pipelines.
