【Haichuan Chemical Salary Update】Dalian Petrochemical Company’s SIL assessment was successfully completed and approved
Thread Content
To improve the reliability of the safety instrumented systems (i.e., functional safety) and standardize daily maintenance activities, so as to meet the production requirements of the facilities as well as the relevant requirements stipulated in Document No. 116, CNPC Dalian Petrochemical Branch entrusted Qingdao Ousaisi Environmental and Safety Technology Co., Ltd. to conduct SIL assessments of 38 sets of equipment in 10 production workshops at Dalian Petrochemical Company. During the evaluation period, SIL assessment experts from the American company KENE*S were hired as technical consultants to clarify roles and responsibilities and cooperate actively to ensure the smooth implementation of the project. From December 6, 2017, to March 30, 2018, the evaluation team visited the Dalian Petrochemical Company on several occasions in four different groups, discussing the SIL classification and recommended measures with personnel in charge of processes, instrumentation, equipment, and safety. From April 5, 2017, to April 30, 2018, the verification team visited the Dalian Petrochemical Company’s site to discuss the SIL verification progress and recommended measures with workshop process engineers, instrumentation specialists, equipment technicians, and safety personnel. As of July 2018, thanks to the efforts of the evaluation team and the active cooperation of the company, all tasks related to the SIL evaluation for Dalian Petrochemical Company had been completed, and the final report for the company was submitted. The SIL assessment process is mainly divided into eight stages: preliminary preparation, holding a project kickoff meeting, data collection and analysis, SIL grading, sharing the results of the SIL grading, SIL verification, formulating recommended measures and preparing reports, as well as review and acceptance. Based on risk analysis, this project employs the Layer of Protection Analysis (LOPA) method to determine the SIL level of the safety instrumented functions (SIFs) involved in the plant. For accident scenarios that do not meet the enterprise’s acceptable risk criteria, additional safety instrumented functions SIFs are added and their SIL levels are determined, thereby enabling a proper assessment of the integrity level required for the plant’s safety instrumented system. The SIF circuits that require verification are subjected to verification calculations using E*da’s exSILENTIA software, and improvement suggestions are proposed for those SIF circuits that fail to meet the required SIL target level. By conducting a SIL assessment of the plant’s safety instrumented systems and implementing the recommendations from that assessment, the level of safety management in the production plant can be effectively improved. This evaluation process has received unanimous recognition and praise from the enterprise
SIL2 certification is an internationally recognized functional safety certification; its full English name is Safety Integrity Level. It is the certification requirement for conducting safety assessments on related products in accordance with the functional safety standard IEC 61508 issued by the International Electrotechnical Commission IEC (which has been translated into the national standard GB/T 20438, under the jurisdiction of the standards committee SAC/TC124/SC10). Products that require SIL certification are those used in situations where they may cause significant harm to people, the environment, or property. The main purpose of this assessment is to ensure that functional defects in the products do not lead to injuries to people, environmental pollution, or property damage. SIL certification is divided into 4 levels in total: SIL1, SIL2, SIL3, and SIL4, covering both the product and system levels. Among them, petrochemical instrumentation is classified as SIL2 and SIL3. As industrial accidents and their impact on society become more widely recognized, an increasing number of companies are aware of the importance of safety. They make use of engineering expertise and safety standards such as IEC61508 and IEC61511 to develop their products, and actively participate in the functional safety certification of these products in order to prevent the occurrence of industrial safety incidents again.
His certification is an Italian certification
I’m still learning this*. Does the power industry also require a similar DCS operation certificate?

There’s a problem with this certificate; for 61508, only the 2000 and 2010 versions exist – where did the 2008 version come from?
Was worried about not knowing what “SIL” meant; I’ve learned about it now and have a basic understanding
The pheasant certificates issued by ECM are already widely despised in the market; don’t bring them out and bring shame upon yourself.
SIL certification is divided into 4 levels in total: SIL1, SIL2, SIL3, and SIL4, covering both the product and system levels. Among them, the requirements for SIL4 are the highest. The SIL level that safety-related systems should achieve is determined through risk analysis, which is carried out by evaluating four factors: the severity of the potential consequences of risks, the duration and frequency of exposure to those risks, the probability that risks cannot be avoided, and the probability of undesirable events occurring. The higher the level, the lower the required probability of hazardous failure.
