本文件规定了受已知或可预见类型作用的海洋结构物的结构完整性管理（SIM）原则。 本文件规定了适用于石油和天然气行业的以下类型固定式海上钢结构的要求并提供了建议: -独立式和支撑式沉箱； -夹克； -单塔； -塔楼。 本文件适用于上部结构，包括但不限于主甲板、甲板支腿、上部结构模块、起重机底座、直升机甲板、钻井井架、滑梁、火炬臂、排气塔、无线电塔、导线支架和救生艇吊柱。 此外，在其要求相关的范围内，本规范适用于符合要求的底部基础结构、钢制重力结构、自升式平台、其他底部基础结构和其他与海洋结构相关的结构（例如水下储油罐、桥梁和连接结构）。 本文件包含以下任务的规划和工程要求: a） 完整性管理数据要求； b） 新结构和现有结构的在役检查和完整性管理； c） 评估现有结构； d） 评估不同位置重复使用的结构； e） 评估未来拆除的构筑物。

This document specifies principles for the structural integrity management (SIM) of offshore structures subjected to known or foreseeable types of actions. This document specifies requirements and provides recommendations applicable to the following types of fixed steel offshore structures for the petroleum and natural gas industries: — caissons, free-standing and braced; — jackets; — monotowers; — towers. This document is applicable to topsides, including but not limited to the main decks, deck legs, topsides modules, crane pedestals, helideck, drilling derrick, skid beams, flare booms, exhaust towers, radio tower, conductor support frames, and lifeboat davits. In addition, it is applicable to compliant bottom founded structures, steel gravity structures, jack-ups, other bottom founded structures and other structures related to offshore structures (e.g. underwater oil storage tanks, bridges and connecting structures), to the extent to which its requirements are relevant. This document contains requirements for planning and engineering of the following tasks: a) integrity management data requirements; b) in-service inspection and integrity management of both new and existing structures; c) assessment of existing structures; d) evaluation of structures for reuse at different locations; e) evaluation of structures for their future removal.
