Regarding the HAZOP review meeting
Thread Content
Hello everyone! Our company supplies goods to the British company BP, mainly one piece of equipment. To better implement the HSE plan, they will organize the conduct of Hazop analyses on the equipment supplied by each supplier. BP has informed us to prepare for this HAZOP review meeting; meanwhile, it is a foreigner from Italy who is in charge of the process. We have not attended any similar meetings before. Friends who have attended such meetings, please help me figure out how to prepare for it I want to say thank you here on Ai! This post was last edited by WSL01218 on 2008-10-13 07:41]
Sorry, I made a mistake earlier; it’s the HSE (Health, Safety, Environment) plan
Don’t worry; they have their own analysis programs. You just need to figure out your own device. They will ask you questions according to the procedure, especially regarding the consequences of an emergency shutdown or malfunction of the equipment, as well as in the event of a leak.
As mentioned on the third floor, it is necessary to have a good understanding of how to operate the equipment, as well as a basic knowledge of the processes involved. Hazop stands for Hazard and Operability Analysis; foreigners will ask you questions according to a set procedure, asking what your plans are in case of certain problems occurring. For example, 1. Pipeline overpressure, resulting in: damage to the pipeline or equipment; preventive measure: safety valves on the pipeline. That’s more or less it.
I agree with the opinion above, but currently many petrochemical users in China do not require suppliers to attend HAZOP meetings
HAZOP meetings are really time-consuming; a typical small process takes about a week. For those working in process engineering, you need to participate in all the specialized HAZOP studies – this can improve the equipment significantly. I think these meetings are just a formality, used to shift the responsibility for safety to the person in charge of HAZOP – that’s all! I’ve attended two such meetings as the person in charge of the process; what happens there is mainly arguing, followed by sleeping. . . . It’s just about handling each tube one by one: what to do in case of overpressure, what to do in case of low pressure, what to do in case of overheating, what to do in case of low temperature, what to do in case of excessive flow, and what to do in case there is no flow at all. . . What can you do if it’s extremely boring? . . . I hope you’re mentally prepared to be tortured! ! !
Thank you for your guidance! Our company is providing a gravity valveless filter to BP; regarding the HAZOP meeting, they plan to allocate an afternoon for its review. And it is required to be done in English; since I haven’t participated before, I’m inevitably a bit worried – one concern is how the technical staff will handle things, and the other is on-site translation support
HAZOP (HAZard and OPerability study) translates to “Hazard and Operability Analysis” in Chinese; it involves an experienced team of multidisciplinary experts who raise safety-related issues regarding the design and operation of a facility, and then work together to discuss solutions to those issues. In the study, the continuous process flow was divided into many segments. Based on the relevant design parameter guidelines, questions were raised regarding possible deviations from the design standard parameters in terms of processes or operations. The team leader guided the team members in identifying the causes of such deviations. If those deviations led to potential hazards, the team members would provide a brief description of those hazards, assess whether safety measures were sufficient, and make recommendations for design and operation improvements. The team leader was responsible for making decisions or proposing more effective safety measures to address the issue. This method is applied repeatedly to each process step of the design until every process step or equipment has been analyzed; only then is the HAZOP analysis completed.
The input information list for this design Phase Hazop study: 1) P&ID/process description 2) PSA/MSDS 3) PFD/H&M balance 4) Process Control Logic–Sequence diagrams / instrument list 5) List of process equipment, data sheets, and other process-related documents such as PSV data sheets 6) Layout plans/equipment layout drawings/HAC drawings 7) MCA/Dow index or other supporting materials 8) Operation manuals/instructions, if available 9) Typical Hazop studies of similar processes, if available. Domestic companies do not have strict requirements regarding HAZOP studies, but foreign clients place considerable importance on them. At least the outward appearances are taken very seriously. It’s sufficient for you to be familiar with your own manufacturing processes and equipment; of course, you need to have a solid understanding of design principles as well. If you have any questions, you can also contact me. I’ll try to see if I can help you.
From what the original poster said, it seems the project is in Zhuhai. BP and TECHNIP are quite strict regarding safety, so one needs to be mentally prepared.:handshake
I’ve learned quite a bit, thank you! I’m about to encounter such a problem as well
I finally returned to the company today. Looking back at this meeting, I now understand the foreigners’ true intentions, and I think it’s very necessary to hold meetings like this! It was originally planned to start the meeting at 1 p.m. yesterday, but they hadn’t finished the HAZOP STUDY for another company by morning, so we had to wait. Around 3:40 p.m., they informed us that their meeting was over and that they would take a short break before starting again. It started at 4:00 sharp, and An analyzed them one by one following the established procedure. There were over 50 items in total, covering almost all possible issues; some of these issues hadn’t occurred to us during the design phase, and it was only at this meeting that we became aware of them after the foreigners raised them. These approaches represent a technical improvement in terms of design. Therefore, I think such meetings are still meaningful.
Here, I would like to thank all the friends mentioned above for their help. It is because of your support that I have the courage and confidence to be in front of foreigners! Thank you all!
It’s truly valuable to be able to draw inspiration from customer analysis and apply it to the design. I wonder if you have used tools such as FMECA when working on product design, to take into account both functional implementation and risk mitigation from the design stage onward. When participating in clients’ hazop sessions in the future, your previous FMEDA analysis will enable you to handle things more smoothly and also satisfy the clients better.
The purpose of HAZOP is to assist in analysis, identify problems, and find solutions. Those who participate are mainly process engineers and instrumentation and control specialists. The HAZOP leader is not responsible for engineering issues; it is incorrect to assign such responsibilities to them. They merely serve as a tool to guide designers in their analysis. I haven’t participated in any domestic analyses, but judging from the way domestic projects are carried out, it’s likely that the results won’t be very significant; it’s all just for show.
I have participated in it; it involves listing all possible accidents and then analyzing how to avoid them
Analyze all possible accidents and their solutions
That’s right; I’ve participated as well and found it to be very necessary
