Guidance on performing risk assessment in the design of onshore LNG installations including the ship/shore interface 陆上液化天然气装置(包括船/岸界面)设计中的风险评估指南
发布日期: 2022-12-13
本文件为那些使用基于风险的方法和标准对陆上和海岸线液化天然气设施的规划、设计和运营进行重大安全危害评估的人员提供了通用方法和指南,以实现液化天然气设施的安全设计和运营。本文件未涉及与液化天然气释放相关的环境风险。 本文件适用于出口和进口码头,但也适用于其他设施,如卫星和调峰工厂。 本文件适用于码头周边内的所有设施和所有危险材料,包括液化天然气和相关产品:液化石油气、加压天然气、除臭剂和码头内处理的其他易燃或危险产品。航行风险和液化天然气油轮固有操作风险得到认可,但不在本文件的范围内。港口、设施和船舶之间的接口产生的危险得到解决,要求通常由港口当局给出。假设液化天然气运输船根据IGC规范设计,接收船用燃料的液化天然气燃料船舶根据IGF规范设计。 港口运营和液化天然气设施之间的边界是船/岸连接(SSL)建立的时候。 本文件无意指定可接受的风险水平;然而,参考了可容忍风险水平的例子。 见IEC?31010和ISO?17776关于一般风险评估方法,而本文件侧重于液化天然气行业内的具体需求场景和实践。

This document provides a common approach and guidance to those undertaking assessment of the major safety hazards as part of the planning, design, and operation of LNG facilities onshore and at shoreline using risk-based methods and standards, to enable a safe design and operation of LNG facilities. The environmental risks associated with an LNG release are not addressed in this document.

This document is applicable both to export and import terminals but can be applicable to other facilities such as satellite and peak shaving plants.

This document is applicable to all facilities inside the perimeter of the terminal and all hazardous materials including LNG and associated products: LPG, pressurized natural gas, odorizers, and other flammable or hazardous products handled within the terminal.

The navigation risks and LNG tanker intrinsic operation risks are recognised, but they are not in the scope of this document. Hazards arising from interfaces between port and facility and ship are addressed and requirements are normally given by port authorities. It is assumed that LNG carriers are designed according to the IGC code, and that LNG fuelled vessels receiving bunker fuel are designed according to IGF code.

Border between port operation and LNG facility is when the ship/shore link (SSL) is established.

This document is not intended to specify acceptable levels of risk; however, examples of tolerable levels of risk are referenced.

See IEC31010 and ISO17776 with regard to general risk assessment methods, while this document focuses on the specific needs scenarios and practices within the LNG industry.
