基于管道的完整性管理体系已经得到一定程度的发展和实践应用,而钢质储罐尤其是大型LNG储罐的完整性管理概念和相应方法尚处于探讨阶段。从对管道的完整性管理进行解构开始,通过探寻其概念起源、实用目的、技术体系与管理体系的核心,深入剖析了管道完整性管理的实质。在可迁移的基础上,从LNG储罐的基本特征出发并依据相关国际规范,尝试建立LNG全容罐完整性管理概念,提出其主要体系框架,结合一般钢质储罐的风险评价方法及国外对LNG储罐生命周期与老化的最新研究成果,提出LNG储罐的完整性评价方法,从而为我国LNG行业建立完整性管理体系提供积极借鉴,同时丰富完整性管理的内涵。
The pipe-based integrity management system has been developed and applied to some extent. However, the concept and method of integrity management of steel storage tanks, especially large LNG storage tanks, are still in the discussion stage. Beginning with the deconstruction of pipeline integrity management, the essence of pipeline integrity management is analyzed in depth by exploring its conceptual origin, practical purposes, technical system and management system. On the basis of relocatable, starting from the basic characteristics of LNG storage tanks and in accordance with relevant international norms, try to establish the concept of LNG storage tank integrity management and put forward the main system framework, combined with the risk assessment methods of steel storage tanks and foreign pairs LNG tank life cycle and aging of the latest research results, put forward the method of evaluating the integrity of LNG storage tanks, so as to provide a positive reference for the establishment of an integrity management system for China’s LNG industry, while enriching the meaning of integrity management.
