FOR OIL TRANSPORTATION ENTERPRISES

FUNCTIONS:

• Monitoring of material flows during transportation of oil/oil products, drawing up the balances;
• Approval of measured oil/oil products flows based on a balance model using data from APCS, information and metering system, and external systems;
• Provision of trustworthy information about flow parameters to process engineering functions and other subdivisions of an oil producing enterprise, and display of processed data using generated report forms;
• Timely detection of upset process conditions and decision-making on process control;
• Preparation of a full daily package of balanced trustworthy measurement values;
• Keeping a source of trustworthy measurement data for all functions and subdivisions of an enterprise;
• Keeping a record of oil/oil products transportation per pumping directions and types of oil products.

USERS:

Dispatchers, metrologists, process engineers, oil/oil products accounting specialists, production automation specialists.

PECULIARITIES OF SOLUTIONS:

• Real-time data are used from information and metering systems, laboratory information systems and APCS in operation at the enterprise;
• All debalance calculations are done using a mathematic model of utility networks with due regard to the model history;
• Oil balance calculations in nodes of utility networks are done based on measured liquids and their parameters (including density depending on the temperature, pressure and water content);
• Changes of liquid in a vertical steel tank are calculated with due regard to calibration tables;
• Expected values are formed on the basis of direct measurements and with due regard to the status of facilities (operation/shutdown, etc.);
• Measured values are approved taking into account a measurement error;
• Report forms are set up by users;
• Adjustments of input information accepted for oil balance calculations are recorded and audited.
