General average concerns the sharing of qualifying sacrifices and expenses made for the common safety of a maritime adventure.

Cargo can be physically undamaged after a marine casualty and still be held while general average security is arranged. Cargo owners need a document and communication plan as well as an understanding of physical damage cover.
What is general average in marine insurance?
General average concerns the sharing of qualifying sacrifices and expenses made for the common safety of a maritime adventure. The applicable contract and rules determine the adjustment. A cargo owner may be asked to provide security before release even where its goods are undamaged; whether the insurer provides that security depends on the policy and circumstances.
Identify the request before signing
The CMI general average resource provides access to the York-Antwerp Rules and related material. Establish which version is incorporated into the actual carriage contract rather than assuming one edition governs every voyage.
| Request or document | Action for the cargo owner |
|---|---|
| General average notice | Send promptly to the cargo insurer |
| Average bond | Obtain advice on the undertaking before execution |
| Guarantee request | Ask whether the insurer will provide acceptable security |
| Cargo valuation request | Reconcile invoice and shipment details |
| Release instruction | Verify it through the appointed parties |
Do not treat a bond and an insurer's guarantee as interchangeable documents. Keep the adjuster's identity and communications independently verified, particularly where payment or security is requested urgently.
A fictional undamaged shipment
A ship reaches a place of refuge after a casualty. A cargo owner's goods appear sound, but release requires security. The owner should notify its cargo insurer rather than assuming there is no insurance issue because nothing was damaged.
The request for security does not establish the final contribution. The adjustment may take time and involve information from several interests. Keep the security file separate from any physical damage claim, while linking both to the same casualty and shipment.
Check the insurance position early
For future underwriting, disclose the goods, value, voyage and intended cover. Ask how general average and salvage charges are addressed, including relevant exclusions. An uninsured shipment can leave its owner needing to arrange security without an insurer's assistance.
Do not assume an all-risks label answers every general average issue. The cause, terms and insured interest still matter. Nor should a cargo owner assume its contribution is limited to a simple percentage quoted in a news report.
Keep a release and evidence checklist
Retain the bill of lading, invoice, packing list, certificate, casualty notices and correspondence with the insurer and adjuster. Track who has signed documents and which conditions remain before release. Verify any bank details through an established channel.
If cargo is also damaged, arrange survey and mitigation as directed. Separate security, contribution, physical loss, storage and delay expenses so each can be assessed correctly. Obtain advice before waiving rights or agreeing a settlement.
Read marine incident response and cargo insurance fundamentals. Explore cargo cover and contact the team with the notice and shipment reference if you need help identifying the appropriate enquiry route.
Key takeaways
- General average concerns the sharing of qualifying sacrifices and expenses made for the common safety of a maritime adventure.
- Not necessarily. Undamaged cargo may face a security request; the declaration, documents and insurance response need careful checking.
