Marine Expert Advisory Service for Disputes & Litigation Support
A ship collides in restricted waters. A cargo shipment arrives damaged, yet the paper trail tells conflicting stories. A vessel is declared off hire, but the owner and charterer cannot even agree on when the failure began. By the time these disputes reach lawyers, the technical truth is already fragmented. That is typically when a marine expert witness becomes necessary.
The decisions depend on evidence that can withstand scrutiny. Masin brings together marine experts, quantum specialists, and forensic accountants. They rebuild what happened, assess what it cost, and explain the full impact in clear and defensible terms.
When Do You Need a Marine Expert Witness?
Typical situations include:
- A collision or grounding where navigation decisions are disputed under COLREGS (International Regulations for Preventing Collisions at Sea), often between master, pilot, and shore management
- Cargo damage disputes involving stowage, ventilation failure, weather exposure, or handling under Hague-Visby Rules or COGSA (Carriage of Goods by Sea Act)
- Charter party disagreements over speed, consumption, off-hire periods, or alleged underperformance in voyage and time charter agreements
- Insurance claims where seaworthiness, crew actions, or policy coverage are contested after loss
- P&I Club investigations into pollution events, personal injury, or cargo incidents requiring independent causation analysis
- Salvage and wreck removal disputes involving LOF (Lloyd’s Open Form) or SCOPIC (Special Compensation P&I Club Clause) interpretations
- Shipyard construction or repair disputes assessed against contractual specifications and IACS (International Association of Classification Societies) standards
- Arbitration preparation for LMAA, ICC, LCIA, or DIFC-LCIA proceedings where independent expert opinion will be cross-examined
Every incident does not need expert. But once liability becomes arguable, technical facts stop being enough on their own. At that stage, the dispute is no longer about what happened. It is about which explanation a tribunal will accept.
Why Choose Masin as Your Marine Expert Witness

What is a marine expert witness?
A marine expert witness is an independent maritime specialist who provides impartial technical opinion in arbitration, litigation, and formal inquiries. Their duty is to the tribunal, not the instructing party. They explain causation and liability in a form courts and arbitrators can rely on.
