Arbitration About Indonesian Refinery Propane Splitter Flooding
Arbitration Overview: Indonesian Refinery Propane Splitter Flooding
1. Context
A propane splitter is a critical distillation column in refineries that separates propane from heavier hydrocarbons. Flooding occurs when liquid accumulates in the column, reducing separation efficiency, causing pressure excursions, and potentially damaging internals.
In Indonesian refineries, flooding incidents can arise from:
Improper column design (tray spacing, reflux ratio, or column diameter)
Malfunctioning control systems (level, flow, or pressure instruments)
Operational errors (sudden feed surges, incorrect reflux rates)
Tray or packing damage, fouling, or corrosion
Flooding can lead to production loss, safety risks, environmental hazards, and high remediation costs, often triggering arbitration between EPC contractors, equipment suppliers, and refinery operators.
2. Common Arbitration Triggers
Design Deficiencies
Column not designed to handle expected feed variations, causing flooding.
Equipment Malfunction or Damage
Faulty control valves, level sensors, or damaged trays/packing.
Operational or Process Errors
Sudden feed surges, incorrect temperature, or reflux control failures.
Contractual Non-Performance
EPC contractor or supplier failing to meet guaranteed separation performance.
Financial and Delay Claims
Costs for shutdown, repairs, production loss, and environmental compliance.
3. Legal and Contractual Considerations
Contract Type: EPC contracts, supply agreements, and O&M contracts.
Liability Allocation: Panels examine whether flooding arises from design flaws, installation errors, equipment defects, or operator negligence.
Evidence: Process data logs, level and flow recorder charts, column inspection reports, maintenance records, and lab analysis of feed or fouling deposits.
Applicable Law: Indonesian Civil Code, Law No. 30/1999 on Arbitration, and safety/environmental regulations.
4. Illustrative Case Law Principles
Here are six arbitration principles derived from typical propane splitter flooding disputes:
Case 1 – EPC Contractor Design Liability
Principle: Column flooding due to incorrect tray spacing, diameter, or reflux ratio constitutes contractor liability.
Outcome: Panel awarded costs for column retrofit, internals replacement, and process optimization.
Case 2 – Equipment Supplier Fault
Principle: Faulty level transmitters, control valves, or damaged packing causing flooding trigger supplier liability.
Outcome: Supplier obliged to repair/replace defective components and compensate for downtime.
Case 3 – Installation Errors
Principle: Improper assembly of trays, packing, or internals by contractor leads to flooding.
Outcome: Contractor held responsible for reinstallation and associated costs.
Case 4 – Operational Negligence
Principle: Incorrect feed rate, reflux control, or failure to follow operating procedures reduces contractor liability.
Outcome: Arbitration apportioned partial liability to operator for operational mismanagement.
Case 5 – Contractual Performance Guarantees
Principle: EPC contracts guaranteeing separation efficiency allow operators to claim damages for lost production due to flooding.
Outcome: Panel awarded damages based on loss of product yield relative to guaranteed specifications.
Case 6 – Force Majeure Rejected
Principle: Flooding due to design, equipment, or operational issues is not force majeure.
Outcome: Contractor’s force majeure claim rejected; emphasized duty to deliver properly functioning column.
5. Lessons for Refinery Stakeholders
Ensure accurate design of trays, column diameter, and reflux ratio for expected feed conditions.
Implement robust process control systems for level, flow, and reflux management.
Maintain inspection and maintenance logs for internals and sensors.
Keep process operation records to monitor deviations and support arbitration defense.
Clearly define contractual warranties and performance guarantees for separation efficiency.
Consider third-party review or commissioning audit to reduce risk of flooding disputes.
6. Conclusion
Arbitrations concerning propane splitter flooding in Indonesian refineries focus on:
Column design and internal configuration
Equipment integrity and control system performance
Operational practices and adherence to procedures
Contractual performance guarantees and liability allocation
Panels rely on technical process data, inspection reports, and contract interpretation to determine responsibility and assess remediation costs or compensation.
