ISO 17776:2016描述了在海上石油和天然气生产装置设计期间管理重大事故（MA）危害的过程。它为制定策略提供了要求和指导，以防止MAs的发生并限制可能的后果。它还包含一些关于管理运行中MA危害的要求和指导。 ISO 17776:2016适用于 -固定式海上结构物，以及 -用于生产、储存和卸载的浮动系统 石油和天然气行业。 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项目或现有设施的设计变更，也可能与陆上生产设施有关。 本文件中定义的移动式海上装置不包括在内，尽管许多原则可作为指导。水下设施的设计也被排除在外，但如果移动和水下设施可能导致影响海上设施的重大事故，则应考虑其影响。本文件不包括与海上设施相关的施工、调试、废弃或安全风险。 全部或部分应用本文件要求和指导的决定旨在基于对MA危害的可能性和可能后果的评估。

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.
