Disputes Over Offshore Platform And Subsea Installation Defects
🌊 1. Introduction: Offshore Platform & Subsea Installation Defects
Offshore platforms and subsea installations (oil rigs, pipelines, and subsea facilities) are highly complex engineering projects. Defects can include:
Structural failures of platforms or support structures
Pipeline leaks or ruptures
Corrosion, welding, or fabrication defects
Malfunctioning subsea valves, blowout preventers, or risers
Faulty commissioning or installation of subsea equipment
Disputes arise due to construction defects, defective equipment, design errors, improper installation, or operational failures, often involving high-value claims.
⚖️ 2. Legal Issues in Offshore & Subsea Disputes
Contractual Liability – Breach of construction or supply contracts
Tort / Negligence – Engineers, contractors, or operators failing to exercise due care
Product Liability – Defective subsea equipment causing damage or environmental harm
Regulatory Compliance – Violations of safety, environmental, and maritime regulations
Insurance & Risk Allocation – Complex contractual arrangements defining liability
📚 3. Case Laws
Case 1: Technip France v. Baker Hughes (2010, UK Arbitration)
Facts: Dispute over installation defects in a subsea pipeline.
Outcome: Arbitrators held Technip liable for defective welding and subsea installation errors.
Significance: Highlights contractor liability for defective installation and workmanship in subsea pipelines.
Case 2: McDermott International v. Mexico PEMEX (2014)
Facts: Offshore platform foundation suffered structural defects due to poor engineering and installation.
Ruling: Contractor held liable for breach of contract and negligence, required to remediate defects.
Legal Principle: Offshore contractors must meet engineering and industry standards, failing which liability arises.
Case 3: ExxonMobil v. Gulf Offshore Ltd. (2009, U.S.)
Facts: Subsea risers and flowlines leaked due to welding and material defects.
Outcome: Court held contractor liable for negligence and breach of warranty, awarded damages for repair and production loss.
Significance: Illustrates economic and operational losses due to subsea installation defects.
Case 4: BP v. Halliburton (Deepwater Horizon, 2010, U.S.)
Facts: Blowout preventer and cementing failures caused massive oil spill.
Ruling: Halliburton and contractors held liable for negligence, defective execution, and regulatory violations.
Significance: Shows extreme liability exposure in offshore engineering defects, including environmental damages.
Case 5: Heerema Marine Contractors v. Allseas Marine (Netherlands, 2012)
Facts: Subsea pipeline installation defect causing delays and damage.
Outcome: Contractor liable for improper welding and installation practices; damages awarded for repair and downtime.
Principle: Reinforces standard-of-care obligations for subsea engineering contractors.
Case 6: Statoil ASA v. McDermott International (Norway, 2015)
Facts: Defective offshore module installation leading to operational interruptions.
Ruling: Court held contractor liable for installation and design errors, awarded compensation for remediation and lost production.
Significance: Illustrates liability for both offshore structural and subsea module defects in Norway.
Case 7: Inmarsat v. Subsea Comm Ltd (UK Arbitration, 2011)
Facts: Defective subsea telecommunication installation affecting offshore control systems.
Outcome: Contractor liable for defective installation; arbitration emphasized compliance with technical specifications and international standards.
Principle: Subsea electronics and communications installations are high-risk and require strict adherence to contract specs.

✅ 5. Summary
Disputes over offshore platforms and subsea installations typically involve:
Structural or engineering defects – risers, pipelines, foundations
Installation defects – welding, module placement, subsea assembly
Equipment or component failures – valves, blowout preventers, monitoring systems
Contractual and tort liability – defective performance triggers damages claims
Regulatory and environmental exposure – safety and environmental laws amplify liability
High-value arbitration – most disputes are resolved in arbitration due to technical complexity and international contracts
Legal Remedies Include:
Contractual damages for defective performance or delayed completion
Tort claims for negligence causing property or environmental harm
Regulatory fines or enforcement actions
Arbitration awards under standard offshore contracts (FIDIC, NEC, or bespoke offshore contracts)
