标准范围

本文件规定了石油和天然气行业使用的独立腿自升式装置的高架现场特定评估(SSA-E)的要求，并提供了建议和指导。它涉及:a)被占用的未疏散、被占用的疏散和未被占用的自升式钻井平台；b)特定地点的已安装（或高架）相。它还解决了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）。为了确保可接受的可靠性，本文件的规定形成了一种综合方法，其全部用于自升式钻井平台的特定地点评估。当评估在受海冰和冰山影响的区域运行的自升式钻井平台时，评估员打算用ISO 19906和程序中包含的有关冰行动的相关规定来补充本文件的规定用于ISO 35104中包含的冰管理。本文件不涉及设计、往返现场的运输或现场的安装和拆除。本文件仅适用于结构完好且维护充分的独立腿移动自升式钻井平台，通常通过持有有效的认可船级社船级社船级社证书来证明。未持有有效认可船级社证书的自升式钻井平台根据ISO 19902的规定进行评估，并在适用的情况下辅以本文件中的方法。注1井导体可能是自升式作业的安全关键元件。然而，井导体的完整性不是自升式钻井平台特定地点评估过程的一部分，因此本文件中没有涉及。有关该主题的指导，请参见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。

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.
