ISO 19901的这一部分规定了所有者使用的SIM过程工程要求和建议，用于展示现有海上运营平台的结构适应性服务。 ISO 19901的这一部分涉及从概念到停用和/或可能在不同位置重复使用的平台生命周期，适用于: ï，·在结构合适的底部结构上的底层结构部件，包括固定平台，合规塔，歧管和海上结构，作为替代能源概念的一部分; ï，·顶部结构部件，不论结构形式如何，包括浮动设施和自升式

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.
