Abstract: At present, there is no scientific computation basis at home and abroad for the rational allocation of oil spill emergency materials and equipments at the initial stage of oil spill disposal. In this paper, a calculation model for emergency material allocation in the case of oil spill in river was developed to deal with this situation. Firstly, based on the arrangement patterns of oil boom, their equivalent models were proposed, and the calculation models for the allocation of oil boom and suction drag bar were determined. Secondly, the calculation model for the allocation of skimmer was determined according to the number of interception points. Thirdly, the calculation model for the allocation of sorbent felt was proposed after its laying area, laying velocity, recovery velocity and other factors on the surface of the river were analyzed. And finally, the oil spill accident in a certain section of pipeline was taken as an example to compare the calculation result of the models with the current standard. It is shown that the allocation quantity of oil boom stipulated in the current standard is reasonable. This calculation model is of practical significance to the rational allocation of oil spill emergency materials.
