All Implemented Interfaces:
Serializable
public class PipelineElectricalDesign extends ElectricalDesign
Electrical design for pipelines.

Extends ElectricalDesign with pipeline-specific electrical requirements. Pipelines have no rotating equipment but may have significant electrical loads:

  • Electrical heat tracing (EHT): 10-40 W/m depending on pipe diameter and temperature differential, used for hydrate prevention, wax control, or maintaining process temperature
  • Cathodic protection (CP): Impressed current cathodic protection systems for corrosion prevention, typically 0.5-5 kW per transformer-rectifier unit
  • Instrumentation: Pressure/temperature transmitters along pipeline route, typically 0.5-2 kW total

      public PipelineElectricalDesign(ProcessEquipmentInterface processEquipment)
      Constructor for PipelineElectricalDesign.
      Parameters:
      processEquipment - the pipeline equipment

  • Method Details

    • getProcessShaftPowerKW

      protected double getProcessShaftPowerKW()
      Get shaft power from the process equipment.

      Default returns the manually set shaftPowerKW value. Equipment-specific subclasses should override this to read from the process equipment directly.

      Pipelines have no rotating equipment. Shaft power is zero.

      Overrides:
      getProcessShaftPowerKW in class ElectricalDesign
      Returns:
      shaft power in kW

    • readDesignSpecifications

      public void readDesignSpecifications()
      Read design specifications from data sources.

      Subclasses can override to load equipment-specific electrical specifications.

      Overrides:
      readDesignSpecifications in class ElectricalDesign

    • calcDesign

      public void calcDesign()
      Run the electrical design calculation.

      Sizes the motor, optional VFD, cables, and switchgear based on the process equipment's shaft power requirement.

      Overrides:
      calcDesign in class ElectricalDesign

    • calculateAuxiliaryLoads

      private void calculateAuxiliaryLoads()
      Calculate total auxiliary electrical loads for the pipeline.

    • getPipelineLength

      private double getPipelineLength()
      Get the pipeline length in metres from the process equipment.
      Returns:
      pipeline length in metres, or 0 if not available

    • getTotalAuxiliaryKW

      public double getTotalAuxiliaryKW()
      Get the total auxiliary power in kW.
      Returns:
      total auxiliary power in kW

    • isHasHeatTracing

      public boolean isHasHeatTracing()
      Check if heat tracing is enabled.
      Returns:
      true if heat tracing is enabled

    • setHasHeatTracing

      public void setHasHeatTracing(boolean hasHeatTracing)
      Set whether heat tracing is enabled.
      Parameters:
      hasHeatTracing - true to enable heat tracing

    • getHeatTracingWPerM

      public double getHeatTracingWPerM()
      Get heat tracing power in watts per metre.
      Returns:
      heat tracing power in W/m

    • setHeatTracingWPerM

      public void setHeatTracingWPerM(double heatTracingWPerM)
      Set heat tracing power in watts per metre.
      Parameters:
      heatTracingWPerM - heat tracing power in W/m (typical range: 10-40)

    • isHasCathodicProtection

      public boolean isHasCathodicProtection()
