Transfer duty and hydraulic design
Receipt, circulation, tank-to-tank transfer and dispatch cases are defined before flow rate, differential head, pipe diameter and operating envelope are calculated.

Pumps · Metering · Transfer
Reliable transfer depends on the complete hydraulic path. Tank levels, product properties, receipt and dispatch modes, simultaneous operations, measurement duties and shutdown logic must be evaluated as one system.
Receipt, circulation, tank-to-tank transfer and dispatch cases are defined before flow rate, differential head, pipe diameter and operating envelope are calculated.
Pump type, materials, seal arrangement, driver, minimum-flow protection, suction conditions and standby philosophy are selected for the product and operating duty.
Strainers, filters, air eliminators where required, water separation or other conditioning equipment are arranged to protect pumps, meters and downstream operations.
Meter technology, range, accuracy class, temperature and pressure compensation, flow computer and proving method are matched to process control or custody-transfer requirements.
Isolation, check, control, pressure-relief and motor-operated valves are coordinated with manifolds and line routing to control flow and reduce contamination risk.
Pump permissives, valve sequencing, alarms, trips, flow totals and transfer records can be integrated with PLC, SCADA or the terminal automation system.
01
Engineering begins with product properties, storage levels, receipt and dispatch sources, required flow, pipeline length and elevation, simultaneous operations, ambient conditions, power supply, measurement purpose and applicable project rules. Simei Energy develops operating cases, line sizing, pump duty points, NPSH assessment, preliminary PFD or P&ID, control philosophy, equipment data sheets and cause-and-effect logic. Final pump selection is made against the approved system curve rather than nominal flow alone.
02
The supply scope can include baseplate-mounted pump sets, motors or engines, filters, strainers, valves, piping, instruments, meter runs, flow computers, local panels, junction boxes and skid structures. Equipment is coordinated for hazardous-area classification, product compatibility, maintainability and export shipment. Calibration, material certificates, inspection plans, vendor documents, recommended spares and installation interfaces are included according to the approved equipment list.
03
Operational metering supports inventory and process control, while custody-transfer measurement may require higher accuracy, compensation, proving and legal-metrology approval. The selected concept therefore depends on the transaction boundary and local authority requirements. Control logic protects against low suction pressure, blocked discharge, deadheading, excessive flow, seal or bearing alarms and incorrect valve line-up, subject to the project hazard review.
04
Simei Energy can provide installation supervision or integrate mechanical, electrical and control work within an agreed EPC boundary. Testing can cover alignment, pressure and leak tests, flushing, cable and loop checks, instrument calibration, pump rotation, interlocks and performance verification. For a proposal, provide products, tank levels, required flows, receipt and dispatch methods, line lengths and elevations, metering purpose, power supply, automation interfaces and required delivery boundary.

Selection starts with product properties, required flow, total dynamic head, suction conditions, operating range and redundancy. The pump curve is then checked against the calculated system curve and minimum and maximum cases.
Net positive suction head indicates the suction margin available to avoid vapor formation and cavitation. Tank level, vapor pressure, temperature, suction losses and pump requirement must be checked together.
Positive-displacement, turbine, Coriolis or other meter technologies may be suitable. Product viscosity, flow range, pressure loss, accuracy, maintenance and whether the duty is operational or custody transfer determine the choice.
Operational metering supports control and inventory management. Custody-transfer metering is used for commercial transactions and normally requires a defined accuracy class, compensation, proving, traceable calibration and local approval.
Sometimes, but product compatibility, contamination limits, manifold design, line displacement, cleaning, meter range and operating procedures must be assessed. Dedicated paths may be required for sensitive products.
Yes. Status, commands, permissives, alarms, flow rate, batch totals and transfer records can interface with PLC, SCADA or a terminal automation system through the approved control architecture.
No. Simei Energy provides technical services, equipment packages and engineering or EPC delivery. We do not provide investment, financing, EPC+F, BOOT, lease-to-own or deferred-payment funding.
