Class RiserConfiguration

java.lang.Object
neqsim.process.equipment.pipeline.RiserConfiguration
public class RiserConfiguration extends Object
Configuration factory for creating risers with standard geometry profiles.

This class provides factory methods to create pipeline objects configured as risers with appropriate elevation profiles for different riser types (SCR, flexible, lazy-wave, etc.).

Example usage: 


// Create a Steel Catenary Riser
PipeBeggsAndBrills riser = RiserConfiguration.createRiser(RiserType.STEEL_CATENARY_RISER,
    "Production Riser", inletStream, 500.0);
riser.run();

// Create a lazy-wave riser with custom parameters
RiserConfiguration config = new RiserConfiguration(RiserType.LAZY_WAVE);
config.setWaterDepth(800.0);
config.setBuoyancyModuleDepth(400.0);
config.setTopAngle(12.0);
PipeBeggsAndBrills lazyWave = config.create("Lazy Wave Riser", inletStream);
