Phast是一种用于结果分析的软件，安全工程师使用它来评估工业活动的风险，并确定事故的风险和潜在的人员伤亡。 The DNV GL development team is pleased to announce the availability of DNV GL AS Phast & Safeti Offshore 8.4. QRA software package that has become the industry standard for quantitative risk analysis for industries that work with hazardous materials.
The improvements Phast/Safeti 8.7 include:- A new, 64-bit architecture, providing significant performance benefits, particularly for large studies- Explosion and thermal radiation exceedance curves where detailed results have been turned off- New event tree ignition report, providing immediate and delayed ignition probabilities and frequencies[attachment=235020]- Improvements to the GIS, making it easier to transfer data to/from other GIS such as Google Earth, ArcGIS and QGIS- Toxic effect contours for defined ERPG concentrations- Improvements to make it easier to specify long pipeline releases- New materials in the standard list- An upgrade to the 2018 version of the DIPPR database在事故发生之前进行预测和建模一直是安全工程师的愿望之一。在这方面有几种技术和方法。但是，在不使用专家软件的情况下对事故的后果进行建模非常耗时，并且大多与错误相关。 Phast软件是DNV开发的几种产品之一，DNV是风险评估和工业事故的先驱之一。因此，该软件被公认为是公司和政府在工业危害和公共安全方面的决策工具之一。 还：Phast已被广泛审查和评估。此外，由DNV提出的对综合UDM结果模型进行单独研究的结果表明，该模型的理论和预测事件的能力非常有效。该特殊软件用于对工业单元中的火灾，爆炸和有毒物质释放进行建模，目前由全球最大的石油和天然气公司购买和使用。对过程单元中可能发生的事故的后果进行建模是风险评估中最重要的步骤之一。此步骤包括对材料向环境中的释放进行建模，然后对这些材料的毒性，着火或爆炸后果进行建模。如今，由于建模关系及其耗时的解决方案非常复杂，因此该步骤由计算机软件执行。 Phast软件可以对诸如油罐和管道起火和爆炸之类的事件进行建模，并以图形方式显示结果（包括影响范围）。这些结果可用于应急计划和综合设施的危害隐患。       A Quantitative Risk Assessment (QRA) is a formal and systematic risk analysis approach to quantifying the risks associated with the operation of an engineering process. The main objective QRA (Quantitative Risk Analysis) is to determine the potential risks of major disasters having damage potential to life and property and provide a scientific basis for decision makers to be satisfied about the safety levels of the facilities to be set up.
PHAST (Process Hazard Analysis Software Tools) is a Windows–based toolkit, which determines the consequences of accidental releases of hazardous material. It examines the progress of a potential incident from initial release, through forma-tion of a cloud, with or without a pool, to its dispersion. The program uses DNV's unique Unified Dispersion Model (UDM) to apply the appropriate entrainment and dispersion models as the conditions change and to integrate the relevant individual models such that the transition from one behaviour pattern to another is smooth, continuous and automatic. It is applicable to all stages of design and operation across a range of process and chemical industry sectors and may be used to identify situations which present potential hazards to life, property or the environment. SAFETI (Software for the Assessment of Flammable, Explosive and Toxic Im-pact) is the most comprehensive and widely used onshore QRA package available. It is a Windows based system that provides a user friendly, industry standard method for quantifying major chemical risks. It enables analysis of the likelihood and severity of major hazards and makes use of the PHAST models to predict the consequence of major releases. By combining these with their frequencies and taking account of population location and density, along with ignition source location for flammable and explosive effects, a number of presentations of 'risk' are possible. These include risk contours, F/N curves, risk transects and risk ranking at specific points. Phast软件的功能：-在事件发生之前预测事件 -在事件发生之前进行建模 -模拟事故后果 -由工业活动引起的风险 -确定风险量 -因事故可能造成人员伤亡
