【摘要】:經(jīng)濟(jì)發(fā)展需要石油能源的支持,而全球大部分石油資源分布在近海海底或者一些海灣國家,所以海上石油運(yùn)輸事業(yè)得到迅速發(fā)展。石油開采和運(yùn)輸過程中難免有一些人為或者自然原因?qū)е乱缬褪鹿?對生態(tài)和社會造成巨大的影響。及時高效的海上搜救工作可以盡可能最小化溢油帶來的危害,而當(dāng)前的實際是我國海上搜救能力不能滿足對溢油事故的完美處理,這就需要加強(qiáng)對海上搜救人員的培訓(xùn)工作。而搜救演習(xí)會帶來的巨大的資源浪費(fèi),且不能覆蓋全部搜救成員,搜救演習(xí)提供的溢油環(huán)境情況較少,所以研發(fā)海上搜救模擬器意義重大。實現(xiàn)油膜的運(yùn)動預(yù)測以及三維可視化是海上搜救模擬器中重要的一部分。國內(nèi)外對溢油行為和歸宿的研究很多,本文首先對前人研究的油膜運(yùn)動和歸宿模型進(jìn)行歸納總結(jié),運(yùn)用Matlab仿真軟件對模型進(jìn)行仿真分析。然后選用油膜兩階段的擴(kuò)展模型構(gòu)成靜止點(diǎn)瞬時溢油的整體過程,即第一階段采用橢圓擴(kuò)展模型,第二階段采用呈正態(tài)分布的油粒子模型,漂移過程采用SURF漂移模型,蒸發(fā)和乳化采用StiverMackay蒸發(fā)模型和Mackay乳化模型。最后在航海模擬器中對靜止點(diǎn)瞬時溢油模型進(jìn)行多次迭代,基于Open GL編程語言,采用OSG場景渲染技術(shù)以及GPU三維渲染編程技術(shù),實現(xiàn)運(yùn)動點(diǎn)連續(xù)溢油三維可視化。將軌跡預(yù)測結(jié)果與較成熟的海洋環(huán)境資源管理及風(fēng)險評估系統(tǒng)實現(xiàn)的油膜軌跡預(yù)測進(jìn)行比較,驗證本研究溢油預(yù)測及三維可視化的合理性,為海上搜救模擬器的研發(fā)打下基礎(chǔ)。
[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.
