public class Umbilical extends ProcessEquipmentBaseClass
Subsea Umbilical equipment class.

An umbilical is a bundled assembly of tubes, hoses, and cables used to:

  • Supply hydraulic fluid for valve actuation
  • Supply electrical power for subsea equipment
  • Transmit control signals and data
  • Inject chemicals (MEG, methanol, scale inhibitor, corrosion inhibitor)

Umbilical Types

  • Steel Tube Umbilical (STU): Thermoplastic hoses replaced by steel tubes
  • Thermoplastic Hose Umbilical: Traditional design with nylon/PE hoses
  • Integrated Production Umbilical (IPU): Combined with small bore production
  • Electro-Hydraulic: Combines hydraulic and electrical functions

Design Standards

  • API RP 17E - Specification for Subsea Umbilicals
  • API Spec 17E - Specification for Subsea Production Control Umbilicals
  • ISO 13628-5 - Subsea Umbilicals
  • DNV-ST-F101 - Submarine Pipeline Systems (for steel tubes)

Usage Example

// Create steel tube umbilical
Umbilical umbilical = new Umbilical("Main Umbilical");
umbilical.setUmbilicalType(Umbilical.UmbilicalType.STEEL_TUBE);
umbilical.setLength(25000.0); // 25 km
umbilical.setWaterDepth(450.0);

// Add functional elements
umbilical.addHydraulicLine("LP Hydraulic", 12.7, 345.0);
umbilical.addHydraulicLine("HP Hydraulic", 9.5, 690.0);
umbilical.addChemicalLine("MEG", 25.4, 150.0);
umbilical.addElectricalCable("Power", 3, 6600.0);
umbilical.addFiberOptic("Control", 12);

// Get mechanical design
UmbilicalMechanicalDesign design = umbilical.getMechanicalDesign();
design.calcDesign();
