【摘要】：经济发展需要石油能源的支持,而全球大部分石油资源分布在近海海底或者一些海湾国家,所以海上石油运输事业得到迅速发展。石油开采和运输过程中难免有一些人为或者自然原因导致溢油事故,对生态和社会造成巨大的影响。及时高效的海上搜救工作可以尽可能最小化溢油带来的危害,而当前的实际是我国海上搜救能力不能满足对溢油事故的完美处理,这就需要加强对海上搜救人员的培训工作。而搜救演习会带来的巨大的资源浪费,且不能覆盖全部搜救成员,搜救演习提供的溢油环境情况较少,所以研发海上搜救模拟器意义重大。实现油膜的运动预测以及三维可视化是海上搜救模拟器中重要的一部分。国内外对溢油行为和归宿的研究很多,本文首先对前人研究的油膜运动和归宿模型进行归纳总结,运用Matlab仿真软件对模型进行仿真分析。然后选用油膜两阶段的扩展模型构成静止点瞬时溢油的整体过程,即第一阶段采用椭圆扩展模型,第二阶段采用呈正态分布的油粒子模型,漂移过程采用SURF漂移模型,蒸发和乳化采用StiverMackay蒸发模型和Mackay乳化模型。最后在航海模拟器中对静止点瞬时溢油模型进行多次迭代,基于Open GL编程语言,采用OSG场景渲染技术以及GPU三维渲染编程技术,实现运动点连续溢油三维可视化。将轨迹预测结果与较成熟的海洋环境资源管理及风险评估系统实现的油膜轨迹预测进行比较,验证本研究溢油预测及三维可视化的合理性,为海上搜救模拟器的研发打下基础。
[Abstract]:Economic development needs the support of oil energy, and most of the oil resources in the world are distributed in the offshore seabed or some Gulf countries, so the maritime oil transportation industry is developing rapidly. In the process of oil exploitation and transportation, it is inevitable that some man-made or natural reasons lead to oil spill accident, which has a great impact on ecology and society. Timely and efficient maritime search and rescue work can minimize the harm caused by oil spill as much as possible, but the current reality is that the maritime search and rescue capability in China cannot satisfy the perfect handling of oil spill accident, so it is necessary to strengthen the training of maritime search and rescue personnel. Search and rescue exercises will bring huge waste of resources, and can not cover all search and rescue members, search and rescue exercises provide less oil spill environment, so the development of maritime search and rescue simulator is of great significance. The motion prediction and three-dimensional visualization of oil film is an important part of maritime search and rescue simulator. There are a lot of researches on oil spill behavior and destination at home and abroad. Firstly, the oil film motion and destination models studied by predecessors are summarized, and the model is simulated and analyzed by Matlab simulation software. Then the extended oil film two-stage model is selected to form the whole process of transient oil spill at the static point. That is, the elliptic expansion model is used in the first stage, the oil particle model with normal distribution is used in the second stage, and the SURF drift model is used in the drift process. StiverMackay evaporation model and Mackay emulsion model were used for evaporation and emulsification. Finally, the instantaneous oil spill model of static point is iterated in the marine simulator. Based on Open GL programming language, the 3D visualization of continuous oil spill of moving point is realized by using OSG scene rendering technology and GPU 3D rendering programming technology. Comparing the trajectory prediction results with the oil film trajectory prediction realized by the mature marine environmental resource management and risk assessment system, the rationality of the oil spill prediction and three-dimensional visualization in this study is verified, which lays a foundation for the research and development of the marine search and rescue simulator.
