【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。更多还原

【Abstract】 On-site maintenance(ONSM) is taken as the universal equipment maintenance schema in the petrochemical industry. Yet many accidents take place during the ONSM processes, due to unstable equipment, complicated work environment and human errors. A new maintenance schema is critical to reduce the probability for accidents during the petrochemical equipment maintenance processes.The problems existed in the equipment maintenance management are firstly analyzed. Based on the characteristics of petrochemical equipment maintenance and the safety benefits of off-site operations, off-site maintenance(OFSM) for petrochemical equipment is proposed, along with the analysis of its implementing condition and processes. Afterwards, information requirements for OFSM are analyzed. A support BIM system for OFSM is developed, which makes use of visualization, information management and localization capabilities. A case study utilizing OFSM and its support system for an oil-loading facility in Ningxia Petrochemical Company is proposed.The application results indicated that the implementation of the BIM-based off-site maintenance can significantly reduce operating risks and improve maintenance efficiency. Under controlled work environment, along with the minimization of on-site risky operations, less congestion and reduction of exposing time to hazards, the improvement of maintenance safety performance is realized. The application of visualization, information management and localization capabilities facilitate the identification of maintenance, the localization of maintenance object and its relevant information. Thus the maintenance efficiency is improved.更多还原
