Abstract

In order to reduce the loss of offshore platform accidents, reasonable dispatch of rescue resources to meet the rescue needs of personnel, taking the emergency rescue of the offshore platform under the explosion accident as the case, considering multiple forms of the evacuation of the target from the platform to the water, a novel optimization method for the scheduling management of rescue ships was proposed based on the drift prediction path. According to the drift prediction model, the drift path of the targets in distress was studied and the search area was determined. By comparing different objective functions, the maximum cumulative probability of success (POS) and the minimum number of dispatched ships were selected as the objectives. Then, the single-objective optimization and multi-objective optimization models were constructed to balance the different objectives. The results show that the ship dispatch planning to each sub-region after integrating multiple distress forms tended to be reasonable compared to single distress forms. It improved the effectiveness of maritime rescue emergency response and avoided scheduling conflicts and the waste of rescue resources. Based on the model, the decision makers could adjust the objective function weights according to different decision needs and then determine the better weight interval to achieve a reasonable allocation of rescue resources. © 2022 China Safety Science Journal.
