Study Notes
Operational Excellence & SCADA
- SCADA philosophy is crucial for seamless operations, effective troubleshooting and informed decision making.
- Control Engineers, Operators, and Managers/Supervisors need to understand SCADA principles.
- Alarm Philosophy: How alarms are triggered, categorized, and managed.
- HMI Style Guide: Principles for intuitive and effective HMI screen design.
- Control Philosophy: Guidelines for Functional Design Specifications (FDS).
Definitions
- Control Room Operator: Trained personnel responsible for SCADA operations.
- FDS: Document detailing the operational requirements and procedures of a system.
- Fully Automated: Tanks equipped with actuators, pumps, safety instruments, and SCADA control for all aspects.
- HMI: Interface between operator and system, used for control.
- Non-Automated: Tanks only equipped with pump control through SCADA, no safety instruments.
- Operator: Person in charge of field operations.
- SCADA: Supervisory Control and Data Acquisition system used for monitoring and control.
- Semi-Automated: Tanks with actuators, pumps, and some safety instruments controlled by SCADA.
Vessel Unloading Automation
General
- Can be commanded from the control room or field HMI.
- Uses tank mass for quantity calculations.
- Selected on the destination tank's function handler.
- Dock line is chosen on the parameter screen.
Truck Loading Automation
General
- Commanded from either control room or field HMI.
- Uses weighbridge for weight calculations.
- Selected on the truck loading bay's function handler.
- Uses 'Land pump' and bypass valve when two pumps are in operation.
Truck Unloading Automation
General
- Can be controlled from the control room or field HMI.
- Uses the weighbridge to determine transferred weight.
- Selected from the truck loading bay's function handler.
- Land bypass valve (XV08) is used when two pumps are available.
Railcar Unloading Automation
General
- Commandable from the control room or field HMI.
- Transfer weight is based on the weighbridge.
- Selected on the truck loading bay's function handler.
- Land Bypass Valve (XV08) is used when there are two P01 pumps (Land and Marine).
Tank to Tank Automation
General
- Commandable from the control room or field HMI.
- Uses tank mass to calculate the transferred quantity.

Vessel to Tank/Railcar Automation
General
- Concurrent operation is only available for tank B110-01.
- Tank function is the primary function and is selected first.
- Tank function controls both vessel and railcars.
- Alarm/stop command on the tank shuts down all functions, while a command on the railcar only affects its function.
- The tank batch can be completed before the railcar batch.
Cleaning
General
- Tank must be set to "Cleaning" status by the control room operator.
- Alarm from level measurement is suppressed during cleaning.
- Control room operator is responsible for choosing the tanks to be cleaned.
- Supervisor level security is required to start cleaning functions.
Cleaning Procedure
