When General Average is announced, Due to the complexity of the adjustment process, there are resulting disagreements caused by some adjustment disputes which are yet to be resolved. This study find that the General Average may have unreasonable points and may lack efficiency in a current maritime industry. Therefore, in light of reasonable and fair loss contribution, we suggest revisions and make proposals for a revised the loss contribution of General Average through marine insurance clauses. We propose the endorsement of supplementary clauses within insurance policy, to cover damage or loss incurred by safety of common maritime adventure, readjustment and contribution of loss by marine insurance system. Accordingly, loss contribution is should be more efficient and fair either by General Average system or marine insurance.
