【摘要】：在线维修是石化行业普遍采用的设备维修策略。然而,由于设备的不安全状态、复杂的作业环境以及人的失误等多方面因素的交互影响,在线维修过程中安全事故频繁发生。探索新的设备维修策略,避免或减少维修安全事故,已成为石化行业设备维修管理亟待解决的一个关键问题。本文首先分析了现有石化设备维修管理存在的问题,结合石化设备维修自身特点,基于离线作业的安全优势,提出了石化设备离线维修模式,并对其实施条件和实施流程进行了介绍。随后,分析了离线维修实施的信息需求,设计开发了基于BIM的石化设备离线维修支持系统,对其可视化、信息管理、定位等功能模块进行了详细分析。最后,以宁夏石化公司油品装车装置的维修为例,对本文提出的基于BIM的石化设备离线维修实施效果进行了验证。研究表明,基于BIM的石化设备离线维修可以降低维修作业风险,提升维修作业效率。在可控的作业环境下,通过最大限度减少现场高危作业量,减少现场人员拥堵及减少维修人员暴露在危险中的时间,提升设备维修安全性;通过系统可视化、信息管理、定位等功能模块的应用,促进维修需求的识别,促进维修人员对维修对象的快速定位及全面认识,提升维修作业效率。
[Abstract]:On-line maintenance is a widely used equipment maintenance strategy in petrochemical industry. However, safety accidents occur frequently during on-line maintenance due to the interaction of many factors, such as unsafe state of equipment, complicated working environment and human error. The exploration of new equipment maintenance strategies to avoid or reduce maintenance safety accidents has become a key problem to be solved urgently in petrochemical industry equipment maintenance management. In this paper, the problems existing in the maintenance and management of the existing petrochemical equipment are analyzed, and the offline maintenance mode of the petrochemical equipment is put forward based on the safety advantage of off-line operation combined with the characteristics of the petrochemical equipment maintenance. And its implementation conditions and implementation process are introduced. Then, the information requirement of off-line maintenance is analyzed, and the off-line maintenance support system of petrochemical equipment based on BIM is designed and developed. The visualization, information management, positioning and other functional modules are analyzed in detail. Finally, taking the maintenance of the oil loading unit of Ningxia Petrochemical Company as an example, the paper verifies the effect of off-line maintenance of petrochemical equipment based on BIM proposed in this paper. The research shows that the off-line maintenance of petrochemical equipment based on BIM can reduce the risk of maintenance and improve the efficiency of maintenance. Under the controllable working environment, the safety of equipment maintenance can be improved by minimizing the number of high-risk operations on the spot, reducing the congestion of field personnel and reducing the time when maintenance personnel are exposed to danger. Through the application of system visualization, information management, positioning and other functional modules, it can promote the identification of maintenance requirements, promote the maintenance personnel to quickly locate and fully understand the maintenance objects, and improve the efficiency of maintenance operations.
