All Implemented Interfaces:

Serializable

public class CompressorInstrumentDesign
extends InstrumentDesign

Instrument design for compressors.

Determines the required instrumentation for a compressor following API 617 / API 670 practice. A compressor typically requires:

• Pressure: suction PT, discharge PT, differential pressure (surge detection)
• Temperature: suction TT, discharge TT, bearing temperatures
• Flow: suction FT (for anti-surge control)
• Vibration: 2x VT per bearing (X-Y probes, API 670)
• Speed: 1x ST (shaft speed transmitter)
• Safety: PSHH (discharge overpressure), TSHH (discharge overtemperature), VSLL (low lube oil pressure)

Constructor Details

CompressorInstrumentDesign

public CompressorInstrumentDesign(ProcessEquipmentInterface processEquipment)

Constructor for CompressorInstrumentDesign.

Parameters:

processEquipment - the compressor equipment

Method Details

calcDesign

public void calcDesign()

Run the instrument design calculation.

Determines the required instruments based on the equipment type and process conditions. Subclasses override this to add equipment-specific instruments.

Parameters:

numberOfBearings - number of bearings

isIncludeAntiSurge

public boolean isIncludeAntiSurge()

Check if anti-surge instrumentation is included.

Returns:

true if included

setIncludeAntiSurge

public void setIncludeAntiSurge(boolean includeAntiSurge)

Set whether anti-surge instrumentation is included.

Parameters:

includeAntiSurge - true to include
