Let me start by talking about what I have experienced: Feasibility study review (mainly focusing on the feasibility of the plan, the process route, cost estimates, as well as safety and environmental aspects...); preliminary design review (focusing on control systems, interlocks, design parameters for mechanical equipment, Hazop analyses, safety and environmental considerations...); detailed design review of construction drawings (focusing on the degree of integration and consistency with the actual site conditions...); the three inspections and four determinations along with subsequent corrective actions; mechanical completion (acceptance by the relevant authorities, installation of pipelines and mechanical/electrical equipment, anti-corrosion and insulation measures, fire protection for steel structures, pressure testing of pipelines and instruments, trial operation of mechanical equipment, calibration of instruments, GS, AFM, automatic fire alarm systems, configuration and tuning of SIS and DCS systems... including all related records); acceptance prior to commissioning (compliance with the three simultaneities principle, review of the trial production plan, start-up plan...); safety and environmental acceptance after one year of trial production... Revision of the design during construction, and archiving of completion documents (determining which documents need to be archived and which do not, in accordance with relevant standards). Is there anything else that is missing? Please feel free to add it. Manager’s discussion group
As titled: 1. From the initial feasibility study stage to the completion of all payments, what are the inspection and approval steps involved in a new petrochemical project? There are many professional options available; the most important thing is to find a reputable design firm. Additionally, it’s essential to have a supervision company as well as one’s own quality control staff to ensure that work is carried out in an orderly manner ； 2. What are the acceptance criteria for each inspection step? Refer to the latest petrochemical regulations ； 3. What is the role of the three checks and four fixations? What should be checked? (What are the design omissions, what are the potential quality issues in the project, and what does \"unfinished work\" refer to?) ) Who will conduct the investigation, and how will it be carried out? (What criteria will be used for the investigation?) ), who will decide (set the time, determine the measures). . ? The three inspections and four determinations rely mainly on the workshop technicians’ experience and design drawings to identify any irregularities or omissions in the construction process. Most importantly, those who will be involved in the construction should be involved from the very beginning, so that many problems can be avoided and rework can be prevented. 4. What standards are available for reference? Still the petrochemical regulations
