Answer
1. GA incident occurs → There must be an extraordinary sacrifice or expenditure, intentionally and reasonably made for the common safety, to preserve property involved in a common maritime adventure from peril.
2. Master informs the owner/company → Master reports the casualty and records all relevant facts, actions, expenditures, log entries, photographs, statements, etc.
3. Shipowner declares General Average → Normally, the shipowner declares GA when circumstances justify it. The owner appoints a professional Average Adjuster.
4. Average Adjuster collects documents → Such as:
- Ship and cargo values
- Bills of lading
- Cargo invoices
- Insurance details
- Salvage/towage expenses
- Repair and survey reports
- Port-of-refuge expenses
- Master's reports and log extracts
5. GA security obtained before cargo release → Cargo interests are normally required to provide security:
- GA Bond — undertaking from cargo owner.
- GA Guarantee — normally from cargo insurer.
- If cargo is uninsured, a cash deposit may be required.
6. Average Adjuster determines allowances → The adjuster decides which sacrifices and expenditures qualify under the applicable York-Antwerp Rules and calculates the contributory values of ship, cargo and, where applicable, freight.
7. Contribution is calculated
GA Contribution=Contributory Value×GA Ratewhere
GA Rate=Total GA Allowances / Total Contributory ValuesExample: If total GA expenditure/sacrifice = $1 million and total contributory value = $20 million, GA rate = 5%. A cargo having a contributory value of $200,000 would contribute $10,000.
8. GA Adjustment is issued → The Average Adjuster prepares the final General Average Adjustment, showing allowable sacrifices/expenditures and each party's contribution.
9. Settlement → Shipowner, cargo owners, freight interests and their insurers pay/receive the amounts according to the adjustment.
