All Implemented Interfaces:
Serializable
public class SubseaProductionSystem extends Object implements Serializable
Unified subsea production system for field development workflow integration.

This class provides a high-level abstraction for modeling subsea production systems, integrating multiple NeqSim components:

Subsea Architecture Types

  • DIRECT_TIEBACK - Wells tied directly to host (short distances, <10km)
  • MANIFOLD_CLUSTER - Wells grouped at subsea manifold then tied back
  • DAISY_CHAIN - Wells connected in series along flowline
  • TEMPLATE - Multiple wells from single seabed template

Example Usage

// Create subsea system
SubseaProductionSystem subsea = new SubseaProductionSystem("Snohvit Satellite");
subsea.setArchitecture(SubseaArchitecture.MANIFOLD_CLUSTER);
subsea.setWaterDepthM(350.0);
subsea.setTiebackDistanceKm(25.0);

// Configure wells
subsea.setWellCount(4);
subsea.setWellheadPressureBara(180.0);
subsea.setWellheadTemperatureC(80.0);

// Set fluid
subsea.setReservoirFluid(gasCondensateFluid);

// Configure flowline
subsea.setFlowlineDiameterInches(12.0);
subsea.setSeabedTemperatureC(4.0);

// Define host facility
HostFacility host = HostFacility.builder("Snohvit LNG").location(71.3, 20.8).waterDepth(350)
    .gasCapacity(20.0, "MSm3/d").build();
subsea.setHostFacility(host);

// Build and run
subsea.build();
subsea.run();

// Get results
double arrivalPressure = subsea.getArrivalPressureBara();
double arrivalTemperature = subsea.getArrivalTemperatureC();
SubseaSystemResult result = subsea.getResult();
