Petrobras UN-BA

Automation of the Carmo, Rio Taquipe, and Almeida/EIA Oil Collection Units

The automation system upgrade is designed to improve data acquisition and process control at the Collection Stations, covering key elements such as waste boxes, production tanks, boilers, separators, treaters, transfer pumps, and, in the case of Almeida, water injection systems.

Integrated Systems with Distributed Control

Each collection station is equipped with two PLCs: one dedicated to process control and the other handling communication. Both PLCs are connected through an Alnet II network, along with existing PLCs in the treaters.

The process PLC oversees system control and interlocking, and communicates via MODBUS protocol with a local HMI, located on the panel door, which manages pump and valve commands, monitors alarms with historical data, and tracks analog variables like pressure and levels. Inputs and outputs are managed through Ponto Series buses, acting as slaves on the PROFIBUS network via the Altus AL-3406 Interface (PROFIBUS Master) located in the Process PLC.

The communication PLC connects with level meters and satellite wells. Additionally, it maintains connectivity with the Operations Center via two networks—Ethernet and Alnet I through radio modem—with the latter used only as a backup if there is an issue with the Ethernet connection.

Predictive Maintenance

Centralized and consolidated data to streamline maintenance activities

Optimized Control

Effective management planning and operational control across the plant

Cost Efficiency

Automated systems designed to reduce operator staffing per shift

Rapid Diagnostics

Quick and efficient identification of equipment failures and system issues

Sistema de supervisão remota via Central de Operações

Remote Supervision System through the Operations Center

The system developed for the Operations Center enables operators to monitor all subsystems and assess the entire process in real time. They can intervene at any moment, taking direct control of various pieces of equipment, notifying stations of any events, and adjusting control set points by interacting with icons and configured interfaces on the screens.
