【摘要】：随着全球经济的高速发展,能源的利用一直受到人们的密切关注。天然气作为新型能源,以其清洁环保、经济高效的特点而越来越受到人们的欢迎。然而天然气在全球范围内分布并不均匀,这必然涉及到运输问题。现在天然气主要是通过管道和LNG船(液货天然气船)进行运输。为满足我国对天然气的需求,“十二五”期间我国从南到北建设了大批的LNG码头,同时会有大量的LNG船舶投入营运,为了保证LNG船舶的安全运营,就需要对船员进行相应的模拟器培训。LNG船的卸货仿真作为LNG船液货装卸模拟器不可分割的一部分,其意义重大。借鉴了由挪威Kongsberg公司引进的LNG船液货装卸模拟器,并以我国建设的“大鹏昊”轮作为母型船,旨在研制出具有自主知识产权的LNG船液货装卸模拟器。本文的主要工作为进行LNG船的卸货模拟仿真。首先在阅读大量的中英文文献的基础上,建立了LNG船液舱温度和压强的响应型模型、液位模型、货泵模型以及其他的一些辅助模型,并利用MATLAB仿真工具对模型进行验证；其次在充分了解LNG船的卸货流程之后,绘制LNG船的卸货流程图,并以此为依据进行程序的开发设计；参照由挪威引进的模拟器的界面设计,设计程序的界面；最后在开发的程序界面的基础上,依照绘制的程序流程图将建立的各种仿真模型融入到程序当中去,使其成为完整的仿真系统。本文通过采用较为简单的数学模型,着重于LNG船液货装卸模拟器的卸货仿真部分的开发与研制。本软件经过一系列的调试和优化,可以独立、高效地完成LNG船的卸货仿真,满足对船员进行LNG船卸货培训的基本要求,其结果令人满意。该系统以Visual Basic6.0为开发工具,完成了LNG船的卸货仿真,为LNG船舶装卸模拟器的进一步研制和完善打下了基础。
[Abstract]:With the rapid development of global economy, the utilization of energy has been paid close attention to. As a new type of energy, natural gas is more and more popular because of its clean, environmental, economical and efficient characteristics. However, the distribution of natural gas in the world is not uniform, which inevitably involves transportation problems. At present, natural gas is mainly transported by pipeline and LNG (liquid and natural gas ship). In order to meet the demand for natural gas in China, a large number of LNG terminals were built from south to north in China during the 12th Five-Year Plan period. At the same time, a large number of LNG vessels will be put into operation. In order to ensure the safe operation of LNG ships, As an integral part of the LNG cargo handling simulator, it is of great significance. The paper draws lessons from the LNG ship liquid cargo loading and unloading simulator introduced by Norway Kongsberg Company, and takes Dapenghao ship constructed in our country as the master ship. The purpose of this paper is to develop the LNG ship liquid cargo loading and unloading simulator with independent intellectual property rights. The main work of this paper is to simulate the unloading of LNG ship. On the basis of reading a lot of literature in Chinese and English, the response model, liquid level model, cargo pump model and other auxiliary models of LNG tank temperature and pressure are established, and the model is verified by MATLAB simulation tool. Secondly, after fully understanding the unloading process of LNG ship, draw the unloading flow chart of LNG ship, and develop the program according to this, referring to the interface design of simulator introduced by Norway, designing the interface of the program; Finally, on the basis of the developed program interface, according to the drawn program flow chart, the various simulation models are integrated into the program to make it a complete simulation system. By adopting a simple mathematical model, this paper focuses on the development and development of the unloading simulation part of the LNG ship cargo handling simulator. After a series of debugging and optimization, the software can finish the unloading simulation of LNG ship independently and efficiently, and meet the basic requirements of LNG ship unloading training for the crew. The result is satisfactory. With Visual Basic6.0 as the development tool, the system completes the unloading simulation of the LNG ship, and lays a foundation for the further development and improvement of the LNG ship loading and unloading simulator.
