Since the original version of this paper was published at the CCPS conference in 2006, the quality and health of asset integrity/mechanical integrity (AI/MI) programs in the process safety community have improved. However, it continues to be a difficult element to develop and implement. In many respects, it is still the “last frontier” of process safety and has been the last element to be fully addressed in the PSM community. This is not to say that inspection, testing, and preventive maintenance and other related activities that are part of AI/MI programs do not exist at facilities with process safety programs. Preventive and predictive maintenance programs have existed in the chemical/process industry for many years. What has been lacking in some cases are complete integrated AI/MI management system programs that address all of the subelements of AI/MI. There are several reasons for this continuing situation:

资产/机械完整性：仍然困扰着 PSM 元素

自 2006 年在 CCPS 会议上发表本文的原始版本以来，过程安全社区中资产完整性/机械完整性 (AI/MI) 计划的质量和健康状况得到了改善。然而，它仍然是一个难以开发和实施的要素。在许多方面，它仍然是过程安全的“最后前沿”，并且是 PSM 社区中最后一个需要完全解决的要素。这并不是说作为 AI/MI 计划一部分的检查、测试和预防性维护以及其他相关活动在具有过程安全计划的设施中不存在。化学/加工工业中的预防性和预测性维护计划已存在多年。在某些情况下，缺少完整的集成 AI/MI 管理系统程序，这些程序可以解决 AI/MI 的所有子元素。这种持续的情况有几个原因：
