Shipping is an inherently risky business, with cargoes and vessels exposed to perils at sea. One of the fundamental principles of maritime law that protects shipowners and cargo owners in extraordinary circumstances is General Average (GA). This principle ensures that all parties involved in a sea voyage share the financial burden of sacrifices made for the common good of the voyage.
This blog will explain General Average, its legal basis, the process of adjustments, and the role of loss adjusters, with an illustrative example and case study.
What is General Average?
General Average is a maritime principle where all stakeholders in a voyage proportionally share losses incurred due to a voluntary sacrifice or extraordinary expense made to preserve the vessel and cargo.

Legal Basis
The GA principle is codified under the York-Antwerp Rules, which establish uniform guidelines for determining GA incidents and contributions.
Conditions for General Average
For an incident to qualify as General Average:
- Voluntary Sacrifice: The action must be intentional, such as jettisoning cargo or flooding compartments to extinguish a fire.
- Imminent Peril: The sacrifice must be necessary to protect the vessel and remaining cargo from a common danger.
- Successful Outcome: The sacrifice must contribute to saving the voyage.
- Proportional Contribution: All parties involved in the voyage contribute to the loss based on their interests.
Example of General Average
Imagine a bulk carrier transporting grain encounters a severe storm. To prevent capsizing, the crew decides to jettison 2,000 metric tons of cargo. The vessel reaches its destination safely, but the loss incurred is shared among all stakeholders.
Stakeholder | Contribution (%) | Contribution Amount ($) |
---|---|---|
Shipowner | 40% | 400,000 |
Cargo Owners | 55% | 550,000 |
Freight Interests | 5% | 50,000 |
Total Loss | 100% | 1,000,000 |
The Role of Loss Adjusters in General Average
Loss Adjusters (also known as Average Adjusters) play a crucial role in calculating GA contributions fairly. Their responsibilities include:
- Assessing the Incident: Determining if the incident qualifies as GA under the York-Antwerp Rules.
- Calculating Contributions: Apportioning the loss among stakeholders based on their interests.
- Handling Security & Claims: Ensuring that security is collected from cargo interests before releasing cargo.
- Finalizing Adjustments: Preparing a detailed General Average Adjustment Report.
The General Average Process
- Incident Occurs – A perilous situation leads to a GA declaration.
- GA Declaration – The shipowner declares General Average and appoints a loss adjuster.
- Security Collection – Cargo owners provide GA Bonds & Deposits as security before cargo is released.
- Assessment & Adjustment – The adjuster calculates contributions and finalizes the General Average Adjustment.
- Settlement – Contributions are collected, and compensations are paid accordingly.
Case Study: MV Maersk Honam
One of the most notable GA cases was the MV Maersk Honam fire (2018). A fire broke out in the cargo hold, leading to the loss of five crew members and significant cargo damage. The vessel declared General Average, and cargo owners had to contribute to the extensive salvage and repair costs.
Stakeholder | Contribution (%) | Estimated Cost ($) |
Shipowner | 30% | 150 million |
Cargo Owners | 65% | 325 million |
Freight Interests | 5% | 25 million |
Total Loss | 100% | 500 million |
The case highlighted the importance of cargo insurance, as uninsured cargo owners faced significant financial strain in meeting their GA obligations.

Conclusion
General Average is a vital concept in maritime trade that ensures equitable loss-sharing among stakeholders. Understanding the role of loss adjusters, the adjustment process, and real-world case studies can help shippers and cargo owners navigate GA situations effectively.
Having adequate marine insurance can mitigate financial risks associated with GA declarations, making it an essential consideration for all maritime stakeholders.
