public class SubseaManifold extends ProcessEquipmentBaseClass
Subsea Production Manifold equipment class.

A subsea manifold gathers production from multiple wells and routes it to flowlines for transport to the host facility. Key features include:

  • Production headers for well gathering
  • Test headers for individual well testing
  • Service/utility headers for chemicals and hydraulics
  • Valve skids with production and isolation valves
  • Flowline connections to export pipelines

Design Standards

  • API RP 17G - Recommended Practice for Completion/Workover Risers
  • API RP 17N - Subsea Production System Reliability
  • DNV-ST-F101 - Submarine Pipeline Systems
  • NORSOK U-001 - Subsea Production Systems

Usage Example

// Create 6-slot subsea manifold
SubseaManifold manifold = new SubseaManifold("Manifold-A", 6);
manifold.setWaterDepth(380.0);
manifold.setDesignPressure(350.0);
manifold.setHasTestHeader(true);

// Add well streams
manifold.addWellStream(well1Stream);
manifold.addWellStream(well2Stream);
manifold.addWellStream(well3Stream);

// Run manifold
manifold.run();

// Get production and test streams
StreamInterface productionStream = manifold.getProductionStream();
StreamInterface testStream = manifold.getTestStream();
