石油和天然气工业. 海上生产装置. 新装置设计期间的主要事故危害管理

[中文适用范围]： 本文件描述了海上石油和天然气生产装置设计过程中重大事故 (MA) 危险的管理流程。 它为制定战略提供了要求和指导，以防止 MA 的发生并限制可能的后果。 它还包含有关管理运行中 MA 危险的一些要求和指南。 本文件适用于 — 固定海上结构和 — 石油和天然气行业生产、储存和卸载的浮动系统的设计。 范围包括所有可能对人员、环境和资产产生重大影响的可信 MA 危害。 本文件适用于开发新海上设施的大型项目。 然而，这些原则也适用于小型或简单的项目或现有设施的设计变更，也适用于陆上生产设施。 尽管许多原则可以用作指导，但本文件中定义的移动式海上装置被排除在外。 海底设施的设计也被排除在外，尽管移动和海底设施的影响也被考虑在内，如果它们可能导致影响海上设施的重大事故。 本文件不涵盖与海上设施相关的建造、调试、废弃或安全风险。 全部或部分应用本文件的要求和指南的决定旨在基于对 MA 危害的可能性和可能后果的评估。 [外文原描述]： ISO 17776:2016 describes processes for managing major accident (MA) hazards during the design of offshore oil and gas production installations. It provides requirements and guidance on the development of strategies both to prevent the occurrence of MAs and to limit the possible consequences. It also contains some requirements and guidance on managing MA hazards in operation. ISO 17776:2016 is applicable to the design of - fixed offshore structures, and - floating systems for production, storage and offloading for the petroleum and natural gas industries. The scope includes all credible MA hazards with the potential to have a material effect on people, the environment and assets. This document is intended for the larger projects undertaken to develop new offshore installations. However, the principles are also applicable to small or simple projects or design changes to existing facilities and can also be relevant to onshore production facilities. Mobile offshore units as defined in this document are excluded, although many of the principles can be used as guidance. The design of subsea facilities are also excluded, though the effects of mobile and subsea facilities are considered if they can lead to major accidents that affect an offshore installation. This document does not cover the construction, commissioning, abandonment or security risks associated with offshore installations. The decision to apply the requirements and guidance of this document, in full or in part, is intended to be based on an assessment of the likelihood and possible consequences of MA hazards.
