Marine General Average
A centuries-old maritime principle requiring all parties in a sea voyage to share proportionally in losses resulting from voluntary sacrifices made to save the vessel and cargo.
What It Is
General Average is a legal principle of maritime law dating back thousands of years. When a voluntary sacrifice or extraordinary expenditure is made to preserve a vessel and its cargo from a common peril, all parties who benefit from that sacrifice must contribute proportionally to compensate the party who suffered the loss.
For example, if cargo must be jettisoned (thrown overboard) to save a sinking vessel, all cargo owners and the shipowner share the cost of the lost cargo proportionally based on the value of their property that was saved. The same principle applies to extraordinary expenses such as emergency towing, port-of-refuge costs, and salvage operations.
General average is declared by the shipowner and administered by average adjusters who calculate each party's contribution. The process can take years to resolve, during which cargo may be held by the carrier as security for the contribution.
Why It Matters for Brokers
General average declarations have become more frequent with the growth in container ship fires and groundings. A single general average event on a large container vessel can involve thousands of cargo interests and contributions totaling hundreds of millions of dollars. Brokers must ensure clients understand that without cargo insurance, they may be required to post a general average bond or cash deposit to retrieve their cargo — even if their specific cargo was not damaged.
Real-World Example
A 20,000-TEU container ship experiences an engine room fire in the Pacific Ocean. The crew activates the CO2 suppression system and the vessel is towed to port at a cost of $12M. General average is declared. A furniture importer with $200K of cargo aboard must post a general average deposit of approximately $30K (proportional to their cargo value relative to the total venture value) before the carrier will release their undamaged containers. The importer's cargo insurance policy covers the general average contribution.
Common Mistakes
- 1Not explaining to clients that general average applies even when their specific cargo is completely undamaged — the contribution is based on saved value, not damage suffered.
- 2Failing to verify that the cargo policy's general average coverage matches the policy's transit valuation, potentially leaving the client short on their contribution obligation.
- 3Underestimating how long general average adjustments take, leaving clients unprepared for cargo delays of weeks or months while security is arranged.
