package neqsim.process.fielddevelopment.tieback
Tie-back analysis package for field development screening.

This package provides tools for evaluating subsea tie-back options to existing host facilities. Tie-backs are a common development concept for marginal fields where building standalone infrastructure is not economic.

Key Classes

  • HostFacility - Represents an existing host platform or FPSO with spare capacity
  • TiebackOption - A specific tie-back configuration with associated costs and constraints
  • TiebackAnalyzer - Evaluates and ranks tie-back options
  • TiebackReport - Comprehensive screening report

Screening Workflow

  1. Define the discovery using FieldConcept
  2. Create a list of potential HostFacility objects with spare capacity
  3. Use TiebackAnalyzer to evaluate each option
  4. Review the TiebackReport to compare options by NPV, distance, and flow assurance

Example Usage

// Define discovery
FieldConcept discovery = FieldConcept.gasTieback("Marginal Gas", 25.0, 2, 1.5);

// Define potential hosts
List<HostFacility> hosts = Arrays.asList(
    HostFacility.builder("Platform A").location(61.5, 2.3).waterDepth(110).spareGasCapacity(3.0)
        .build(),
    HostFacility.builder("FPSO B").location(61.8, 2.1).waterDepth(350).spareGasCapacity(5.0)
        .build());

// Analyze options
TiebackAnalyzer analyzer = new TiebackAnalyzer();
TiebackReport report = analyzer.analyze(discovery, hosts);

// Review results
System.out.println(report.getSummary());
TiebackOption best = report.getBestOption();
