Class SURFCostEstimator

java.lang.Object
neqsim.process.mechanicaldesign.subsea.SURFCostEstimator
public class SURFCostEstimator extends Object
SURF (Subsea, Umbilicals, Risers, Flowlines) CAPEX estimator for field development.

Aggregates cost estimates for all major SURF equipment categories:

  • S — Subsea infrastructure: Christmas trees, manifolds, PLETs, jumpers
  • U — Umbilicals: control umbilicals from host platform to subsea field
  • R — Risers: dynamic or rigid risers from seabed to host platform
  • F — Flowlines: infield flowlines and export pipelines

Cost estimates are based on industry benchmarks for the Norwegian Continental Shelf (NCS) and can be adjusted for other regions using the SubseaCostEstimator.Region parameter. All costs are in USD unless converted.
