ISO/TS 35105:2018为在北极和寒冷环境中运行的海上和陆上石油和天然气设施的材料选择、制造和制造要求、钢结构和部件的测试和鉴定提供了建议。ISO/TS 35105:2018旨在作为现有钢结构标准的补充，该标准未充分说明北极地区的特殊运行条件。ISO/TS 35105:2018给出了确保低温下脆性断裂风险安全运行的特殊要求。这些要求将影响材料等级和设计等级的选择，以及钢材的交货技术条件。它们还将影响制造要求以及测试和鉴定要求。ISO/TS 35105:2018也给出了以下建议:-缓解与上部结构积雪和积冰有关的操作和完整性问题；-在腐蚀评估和腐蚀防护系统要求中考虑特殊的北极运行条件；-为确保北极地区的安全运行而制定的特殊操作要求。本文件中的要求适用于任何工作温度，但与高温下的降额（强度损失）相关的特殊要求未得到解决。由于材料的低温性能，对适用的最低设计温度可能存在限制，但不限于本文件的范围。作为使用本文件的实用指南，低温定义为以下最低预期工作温度（LAST）？10摄氏度。注:关于LAST的确定，见6.3.2。

ISO/TS 35105:2018 provides recommendations for material selection, manufacturing and fabrication requirements, testing and qualification of steel structures and components for offshore and onshore petroleum and natural gas facilities operating in Arctic and cold environments.ISO/TS 35105:2018 is intended to be used as a supplement to existing standards for steel structures where the particular operating conditions in Arctic regions are not sufficiently addressed.ISO/TS 35105:2018 gives particular requirements to ensure safe operation with respect to the risk of brittle fracture at low temperatures. These requirements will affect the selection of material grade and design class as well as the technical delivery conditions for steel. They will also affect the fabrication requirements as well as testing and qualification requirements.ISO/TS 35105:2018 also gives recommendations:- to mitigate the operational and integrity aspects related to snow and ice accretion on topside structures;- to take into account the particular Arctic operating conditions in corrosion assessments and requirements for corrosion protection systems;- for particular operational requirements to ensure safe operation in Arctic regions.The requirements in this document are applicable to any operating temperatures, but particular requirements related to de-rating (loss of strength) at high temperatures are not addressed. Limitations to the applicable minimum design temperature caused by the capability of the materials' low temperature performance can exist, but are not a limitation for the scope of this document.As a practical guideline for the use of this document, low temperature is defined as lowest anticipated service temperature (LAST) below?10 °C.NOTE For determination of LAST, see 6.3.2.
