Before SGO was created, a map of the target region was created by a survey ship, and a detailed map of the marine area was created and delivered. This operation was very costly, took days to complete, and needed to be executed before any equipment or pipe installation could take place. A growing level of offshore activity in the Campos basin increased the number of sea obstacles, and Petrobrás saw the need for a greater degree of planning. The company first commissioned a survey ship to map the entire basin, and the initial database was used to generate a comprehensive map of obstacles. Workers in the basins now send daily reports of their activities to the Geodesy Management team, which updates the system overnight. The 800 users of the system can access the updated information online. SGO is currently being used on any project involving offshore installations of pipes, platforms, and wells in four oil basin areas, covering an area of about 160,000 square kilometers with 40,000 registered obstacles. The firm’s goal was to eliminate environmental accidents — for example, a ship anchoring near submarine pipes or a pipe overlapping another and causing a leak. The system also decreases the cost of pipe installation because workers can determine the path in advance. The company also wanted the ability to research and recover obstacles in the basin. Developed using MicroStation, the new system enables a user to simply select an area of interest and all surface and deep-sea obstacles can be quickly visualized in 3D, facilitating fast determination of obstacle characteristics. Savings from the use of this system total as much as $100,000 per day by reducing the time required to install pipelines by up to 40 percent. BE AWARDS OF EXCELLENCE 91
