Arbitration Involving Lng Storage Tank And Pipeline Defects
1. Overview
LNG storage tanks and pipelines are critical infrastructure in the energy and gas sector. Defects in these systems can lead to:
Safety hazards including leaks, explosions, or environmental contamination.
Operational shutdowns and production losses.
Regulatory compliance violations and fines.
Substantial financial losses due to repairs, downtime, or compensation claims.
Disputes often arise between EPC contractors, equipment suppliers, operators, and engineering consultants. Arbitration is preferred because:
LNG contracts typically include arbitration clauses due to the high stakes and technical complexity.
Technical expertise is required to assess design, materials, welding, insulation, and operational safety.
Arbitration ensures faster resolution than courts, preventing prolonged plant downtime.
2. Common Causes of Arbitration in LNG Storage Tanks and Pipelines
Design Deficiencies: Inadequate pressure ratings, thermal insulation, or stress allowances.
Material Defects: Substandard steel, welds, valves, or insulation materials.
Construction and Installation Errors: Improper welding, pipeline alignment, or tank assembly.
Commissioning and Testing Failures: Failed hydrostatic, leak, or cryogenic tests.
Corrosion or Cryogenic Damage: Premature corrosion, embrittlement, or insulation failure.
Operational Failures: Valve malfunction, instrumentation errors, or leak detection system failures.
Regulatory Non-Compliance: Deviations from ASME, API, or local safety standards.
3. Arbitration Process in LNG Defect Disputes
Notice of Dispute: Party identifies defects or failures and issues formal notice.
Appointment of Arbitrator(s): Often includes mechanical and pipeline engineering experts.
Evidence Submission:
Inspection and non-destructive testing (NDT) reports
Welding and material certificates
Design, construction, and commissioning documents
Operational logs and maintenance records
Expert Evaluation: Independent experts assess defect causation, design adequacy, and construction quality.
Hearings: Presentation of evidence, technical demonstrations, and expert testimony.
Award:
Repair or replacement of defective tanks/pipelines
Compensation for operational downtime or losses
Allocation of arbitration costs
4. Case Laws (Illustrative)
Case 1: LNG Storage Tank Cryogenic Leakage
Facts: Storage tank developed minor LNG leakage after commissioning.
Arbitration Held: Investigation identified improper weld joints and defective insulation.
Outcome: Contractor held liable; awarded costs for repair and inspection, plus operational losses.
Case 2: Pipeline Corrosion Before Commissioning
Facts: LNG pipeline showed signs of accelerated corrosion.
Arbitration Held: Material analysis confirmed use of substandard steel not compliant with contract.
Outcome: Supplier and EPC contractor jointly liable; pipeline replaced and damages awarded.
Case 3: Defective Valves Causing Operational Shutdown
Facts: Multiple valves in LNG transfer pipeline failed, halting operations.
Arbitration Held: Expert review traced defects to manufacturing faults and improper installation.
Outcome: Manufacturer and installer held responsible; awarded costs for valve replacement and downtime compensation.
Case 4: Tank Settlement and Structural Deformation
Facts: LNG storage tank foundation settled unevenly, causing deformation and operational risks.
Arbitration Held: Geotechnical and structural analysis confirmed design deficiency in foundation support.
Outcome: Engineering consultant and contractor held liable; rectification works and compensation awarded.
Case 5: Insulation Failure in Cryogenic Pipeline
Facts: Pipeline insulation failed, leading to excessive boil-off gas losses.
Arbitration Held: Thermal analysis confirmed improper insulation installation by contractor.
Outcome: Contractor required to reinstall insulation; damages awarded for lost LNG and operational losses.
Case 6: Leak Detection System Malfunction
Facts: LNG leak detection system failed to alarm during testing, posing safety risk.
Arbitration Held: Investigation confirmed electrical and sensor installation defects.
Outcome: Contractor liable for system rectification and additional safety audits.
5. Key Takeaways
Technical Expertise is Essential: Arbitrators rely heavily on material testing, NDT reports, and structural/thermal analysis.
Contractual Terms Govern Liability: Warranties, design responsibility clauses, and performance guarantees are crucial.
Safety Compliance is Non-Negotiable: LNG systems pose high safety risks; non-compliance can increase liability.
Timely Arbitration Minimizes Operational Losses: Quick resolution prevents prolonged shutdowns and financial loss.
Joint Liability is Common: EPC contractors, designers, and equipment suppliers are often jointly held responsible depending on the defect.
