Abstract: In order to set the price of ship clean-up expenditure and take into account both the principles of equity and efficiency, this paper divides the risk rating according to the risk of ship pollution accident in port, and then apportions the allocation cost of port clean-up resources by simplified formula of Shapley value, to calculate the allocation cost shared by each ship per day. The results eliminate the effect of dynamic berthing on the cost apportionment and can be used as the theory basis for setting the price of the ship clean-up expenditure. The case indicates that the current standard is too high, and this result takes into account the principle of equity and efficiency, which meets the requirement of individual rationality, group rationality and coalition rationality.

Key words: ship clean-up expenditure, equity and efficiency, Shapley value, stability, cost apportionment
