public class PLEM extends ProcessEquipmentBaseClass
Pipeline End Manifold (PLEM) equipment class.

A PLEM is a subsea structure that provides multiple pipeline terminations and connections, typically used to:

  • Connect multiple flowlines to a single export line
  • Provide manifolding for multiple wells
  • Enable pipeline crossings with valved connections
  • Allow routing changes between pipelines

Design Standards

  • API RP 17G - Subsea Production System Design
  • API RP 17N - Subsea Production System Reliability
  • DNV-ST-F101 - Submarine Pipeline Systems
  • NORSOK U-001 - Subsea Production Systems

Usage Example

// Create PLEM for 4-slot manifold
PLEM plem = new PLEM("PLEM-A", 4);
plem.setWaterDepth(450.0);
plem.setDesignPressure(200.0);
plem.addInletStream(well1Stream);
plem.addInletStream(well2Stream);
plem.run();

Stream comingledStream = plem.getOutletStream();
