石油和天然气工业 包括低碳能源 移动式海上装置的现场评估 第 1 部分：自升式钻井平台：在现场升高

[中文适用范围]： 本文件规定了用于石油和天然气工业的独立腿自升式平台的现场特定评估 (SSA-E) 的要求，并提供了建议和指导。它涉及：a) 有人居住的非真空、有人居住的真空和无人居住的自升式平台；b) 特定场地的安装（或升高）阶段。它还涉及安装状态与评估中使用的假设相匹配的要求。本文件不涉及安装和拆除的现场特定评估 (SSA-I)。为确保可接受的可靠性，本文件的规定形成了一种综合方法，该方法可完整用于自升式平台的现场特定评估。在评估在受海冰和冰山影响的地区作业的自升式平台时，评估人员应使用 ISO 19906 中有关冰作用的相关规定和 ISO 35104 中的冰管理程序来补充本文件的规定。本文件不涉及设计、往返现场的运输或安装和从现场移除。本文件仅适用于结构坚固且维护良好的独立腿移动式自升式平台，这通常通过持有有效的公认船级社分类证书来证明。未持有有效的公认船级社证书的自升式平台将根据 ISO 19902 的规定进行评估，并在适用的情况下补充本文件中的方法。注 1 井导管可能是自升式平台作业的安全关键要素。但是，井导管的完整性不是自升式平台现场特定评估过程的一部分，因此本文件不涉及。有关此主题的指导，请参阅 A.1。注 2：RCS 规则和 IMO MODU 规则（国际海事组织移动式海上钻井装置规则）为自升式钻井平台的设计提供了指导。 [外文原描述]： This document specifies requirements and provides recommendation and guidance for the elevated site-specific assessment (SSA-E) of independent leg jack‑up units for use in the petroleum and natural gas industries. It addresses: a) occupied non-evacuated, occupied evacuated and unoccupied jack‑ups; b) the installed (or elevated) phase at a specific site. It also addresses the requirement that the as-installed condition matches the assumptions used in the assessment. This document does not address the site-specific assessment of installation and removal (SSA-I). To ensure acceptable reliability, the provisions of this document form an integrated approach, which is used in its entirety for the site-specific assessment of a jack‑up. When assessing a jack-up operating in regions subject to sea ice and icebergs, it is intended that the assessor supplements the provisions of this document with the relevant provisions relating to ice actions contained in ISO 19906 and procedures for ice management contained in ISO 35104. This document does not address design, transit to and from site, or installation and removal from site. This document is applicable only to independent leg mobile jack-up units that are structurally sound and adequately maintained, which is normally demonstrated through holding a valid recognized classification society, classification certificate. Jack‑ups that do not hold a valid recognized classification society certificate are assessed according to the provisions of ISO 19902, supplemented by methodologies from this document, where applicable. NOTE 1 Well conductors can be a safety-critical element for jack‑up operations. However, the integrity of well conductors is not part of the site-specific assessment process for jack‑ups and is, therefore, not addressed in this document. See A.1 for guidance on this topic. NOTE 2 RCS rules and the IMO MODU code (International Maritime Organisation Mobile Offshore Drilling Unit code) provide guidance for the design of jack-ups.
