【摘要】：本文针对海洋石油202铺管船的系泊运动分析和海洋石油54000吨级大型起重机半潜船压载分析两个示例，使用集成软件EASA对水动力计算软件MOSES进行集成封装，旨在改善在使用MOSES分析问题时命令编写复杂、耗时长、工程使用中修改不便等问题。介绍MOSES对系泊分析问题以及半潜船压载问题的分析过程，并使用EASA将MOSES的计算分析过程集成封装。从封装后的结果上来看，建立了一个用户友好型的使用界面，让使用者脱离了编程过程。实现了封装后软件使用的网络化，增强了软件保密性，使计算结果更加便于储存和管理，并且并未由于对MOSES进行封装而造成计算时间的延长。该封装所形成的计算模块可以成为这一类问题固定标准，例如对于封装的半潜船压载程序，由于不同的SPAR平台在尺寸上来说是基本相同的，所以可以将从拖拉上船开始到完全拖放到船上结束之间的拖拉距离分步骤进行定量化处理，以使本计算模块适用于基本所有的SPAR平台。对于不同的SPAR和对于不同的半潜船，在利用该计算模块时，只需要以相同的文件名向EASA上传相应的船型文件和载荷文件即可进行计算使用，这增强了封装后压载分析模块的适用范围，，使其更具有工程实用性。
[Abstract]:In this paper, two examples of mooring motion analysis of offshore oil 202 tube-laying ship and ballast analysis of semi-submersible ship of 54000 ton offshore oil crane are presented. The integrated software EASA is used to package the hydrodynamic calculation software MOSES. The purpose of this paper is to improve the problems of complex command writing, long time consumption and inconvenient modification in engineering application when using MOSES to analyze problems. The analysis process of mooring analysis problem and ballast problem of semi-submersible ship by MOSES is introduced. From the result of encapsulation, a user friendly user interface is established, which makes the user get rid of the programming process and realize the network of software after encapsulation. It enhances the confidentiality of the software, makes the calculation results easier to store and manage, and does not result in the prolongation of the computing time due to the encapsulation of the MOSES. The computing module formed by the package can be used as a fixed standard for this kind of problem. For example, for a packaged semi-submersible ship ballast program, because different SPAR platforms are essentially the same in size, the drag distance from the start of the towing to the end of the full towing can be quantified step by step. In order to make this calculation module applicable to all basic SPAR platforms. For different SPAR and for different semi-submersible ships, when using the calculation module, It only needs to upload the ship form file and load file to EASA with the same file name, which can be used in calculation, which enhances the applicable range of the ballast analysis module after encapsulation, and makes it more practical in engineering.
