材料：

Following a general average incident，ship agents and surveyors play a significant role．A ship agent，in addition to the normal duties of port and husbandry agency，will assist the master in the aftermath of a general average incident to make a declaration which complies with the local law and custom of the port．

Once the average adjuster has confirmed that security has been obtained from all the interested parties，the agent is instructed by the ship owner to permit delivery of the cargo．If cargo has been discharged to lighten the vessel，or cargo has been transshipped to a final destination，the agent will be responsible for keeping full and complete records of all movements and expenditure attributable to the general average．

After any incident，a large number of surveyors representing various interests will descend on the vessel．Some of these surveyors will not be involved directly in the general average process．However，if it has become necessary to sacrifice or discharge a part of the cargo before arrival at the final destination stated on the bill of lading，the ship owner will appoint surveyors to report on the condition and quantity of cargo．

Such surveyors，usually called general average surveyors，will act in the interests of all the parties involved（and may also represent hull and machinery interests）．If possible，the account representing expenditure incurred should be examined and approved by the general average surveyor before settlement．
