Embodiment Construction

[0067] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0068] For ease of understanding, before explaining and describing the embodiments of the present invention in detail, the application scenarios involved in the embodiments of the present invention are firstly introduced.

[0069] In the process of natural gas gathering and transportation, some process equipment in the gathering and transportation process system will inevitably fail after long-term operation. In order to avoid possible property and economic losses caused by failure of some process equipment and damage to operators, it is possible to pre-assess each process equipment included in the gathering and transportation process system, that is, each SIF of each EUC Perform SIL determination. Among them, the higher the SIL level...

Abstract

The invention discloses a method, device and storage medium for determining SIL, and belongs to the field of natural gas gathering and transportation safety. The method includes: determining at least one SIF corresponding to the EUC, and then determining an equipment correction coefficient and a management system evaluation coefficient of the EUC, and a basic failure probability corresponding to each hazard factor among at least one hazard factor affecting each SIF. Based on the equipment correction coefficient and management system evaluation coefficient, and at least one basic failure probability corresponding to each SIF, determine the theoretical failure probability of each SIF; and determine the failure consequence level of each SIF. Determine the SIL for each SIF based on the theoretical failure probability and failure consequence level for each SIF. The present invention corrects and quantitatively solves the theoretical failure probability of each SIF, and then determines the SIL of each SIF based on the theoretical failure probability and failure consequence level of each SIF, thereby improving the accuracy of the SIL.

Description

technical field [0001] The present invention relates to the field of natural gas gathering and transportation safety, in particular to a method, device and storage medium for determining SIL (Safety Integrity Level, Safety Integrity Level). Background technique [0002] In the process of natural gas production, the safety of the gathering and transportation process system is the top priority of natural gas production. In order to improve the safety of the natural gas gathering and transportation process system, it is usually necessary to evaluate the SIL of each SIF (System Integrated Function, safety instrument function) in each EUC (Equipment Under Control, controlled equipment) included in the gathering and transportation process system, Then determine the safety and reliability parameters of each SIF. Among them, SIL refers to the probability of failure of the minimum response required by the safety instrumented system, so that the EUC can successfully perform the safet...
