Abstract: Marine salvage reward aims to encourage volunteers to rescue properties in distress at sea following by "no cure no pay principle". Based on the equitable apportionment of the rewards,the effective rescue is benefited with sufficient collaboration by all salvors. In practice, the apportionment of rewards is normally calculated on the capital input of the co-salvors, neglecting the contribution of non-capital inputs. In this paper, a solution is present which compensates the capital input of each salvor firstly, then evaluates the contribution of non-capital inputs with two dimensions, which are the importance of the participants and the non-substitutable roles of their resources measured by the algorithm of Shapley value and re-purchase costs separately. This solution can be used for both external and interior apportionment of rewards among salvors and meeting the requests of the relevant international conventions and domestic law of each country thoroughly.

Key words: marine salvage reward, no cure no pay principle, equitable apportionment, re-purchase cost, Shapley value
