Definition:Running-down clause
⚓ Running-down clause is a provision found in marine hull insurance policies that extends coverage to the insured shipowner's legal liability for damage caused to another vessel in a collision, distinct from the physical damage coverage provided to the insured vessel itself. Also known as the collision liability clause, this provision bridges what would otherwise be a gap between hull coverage — which protects the insured vessel against physical loss or damage — and the third-party liability exposures that arise when a ship collides with another vessel and the insured is found legally responsible. The clause has deep roots in marine insurance practice, originating in the London market and codified through the Institute Time Clauses (Hulls), and it remains a standard feature of hull policies written in markets worldwide, including Lloyd's, the Nordic Plan jurisdictions, and Asian marine insurance hubs.
⚙️ When a collision occurs and the insured shipowner is held liable — whether through court judgment, arbitration, or negotiated settlement — the running-down clause responds by indemnifying the insured for the proportion of liability attributable to the insured vessel, up to the insured value of the vessel as stated in the policy. Traditionally, the clause covers three-fourths of the collision liability, with the remaining one-fourth covered by the shipowner's protection and indemnity (P&I) club. This three-fourths / one-fourth split is a longstanding market convention, though some modern hull forms offer full four-fourths collision liability coverage, eliminating the need for P&I club involvement on the collision liability element. The clause typically covers the insured's liability for damage to the other vessel, its cargo, and related expenses such as wreck removal costs of the other vessel, but it generally excludes liabilities for personal injury, loss of life, and pollution — exposures that fall within the domain of P&I coverage. Careful coordination between the hull policy's running-down clause and the P&I entry is essential to avoid gaps or unintended overlaps.
💡 Understanding the running-down clause is fundamental for marine insurance practitioners, shipowners, and their brokers because collision events can generate enormous liabilities — potentially exceeding the value of the insured vessel itself in cases involving damage to laden cargo ships, port infrastructure, or environmental contamination. The clause's traditional limitation to the insured value of the vessel means that catastrophic collision liabilities may not be fully absorbed by the hull policy alone, reinforcing the critical role of P&I coverage as the complementary layer. Disputes over the scope of the running-down clause have produced significant case law, particularly in the English courts, which remain influential in marine insurance interpretation globally. As vessel values and cargo exposures have grown and as shipping routes become more congested, the interplay between running-down clauses in hull policies and the broader liability protections offered by P&I clubs continues to be a key area of focus in marine policy structuring and negotiation.
