I. Introduction II. Review of this year’s work 2011 was a busy year, as well as an important one. This year coincides with the three-yearly major maintenance campaign at XX Petrochemical, and I happen to work in the maintenance project supervision department, which gave me the opportunity to participate in and experience the entire maintenance process. For inspection, maintenance, and repair projects, supervision of the installation of process pipelines and equipment for over 20 projects was undertaken. In mid-November, I was assigned to the XX project team to oversee equipment installation, and I have been doing this job to this day. III. Analysis and summary of work: Before going to the supervision department for inspection and maintenance projects, I subjectively believed that such projects were all minor ones, some sort of \"irregular\" tasks that dealt with trivial matters. But when I joined the project department and took on the work, I found that although the scope of work for inspection and maintenance projects is small, the workload is substantial; as the saying goes, \"Though a sparrow is small, it has all the internal organs.\" After nearly a year of working on maintenance projects, I have the following insights: a) Projects are intricate, and the amount of work required for management and coordination is substantial. Due to the nature of maintenance projects, it is inevitable that multiple projects need to be carried out simultaneously. For us young people, running around the factory every day isn’t a problem in terms of physical strength. However, the practice of subcontracting work at various levels among construction firms is becoming increasingly common; sometimes one has to manage more than a dozen different construction subcontractors at the same time, which results in a huge amount of work related to coordinating on-site construction activities. Additionally, the owner side also has a dozen or so project managers in charge of different projects. Working in such circumstances is not only a workout for one’s ability to manage and coordinate tasks, but it also tests the ability to arrange one’s working hours and tasks reasonably. Sometimes, five or six A-level quality control inspections have to be carried out in a single day; knowing how to arrange one’s own work as well as that of the construction team is also a form of skill development. b) Most are workshop maintenance tasks that are closely integrated with production; many of these maintenance activities are carried out while production is ongoing, and there are many unpredictable factors that can affect the work. For example, in the energy-saving renovation project for the circulation water pumps in the water supply workshop, a total of 4 pump heads need to be replaced. It is necessary to stop production, remove the old pump head and its foundation, then drill holes according to the dimensions of the new pump head’s base and the positioning of the original motor before installing it. Once installation is complete, the system must be put into operation before production can be stopped again to remove another pump. Construction on this project was delayed for over five months due to production issues or the inability to fully close the valves. The aromatic oil sludge pipeline renovation project involves the demolition and replacement of the underground oil sludge pipelines throughout the combined aromatic unit and tank farm. Due to the severe leakage of underground oil, as many as 21 instances of high-risk hot work were required solely during the demolition process, making both construction and safety supervision extremely challenging. The oil waste pipeline, which serves as the “waste discharge port” of the facility, is essential; without it, there is no place to discharge waste in case of fluctuations in the facility’s production. Based on the on-site conditions, all parties jointly agreed on the construction and emergency response plans. Construction is carried out in sections and along separate pipelines; once a small, independent system is completed, it is put into use immediately. In the workshops, temporary measures such as using large tanks to collect oil are employed to prevent there being no place to discharge waste in the event of an accident. The aromatic hydrocarbons workshop has a high groundwater level, which causes water accumulation once excavation takes place. Moreover, the aromatic hydrocarbon-contaminated oil has a high freezing point; therefore, buried pipelines must be equipped with heating systems for insulation as well as anti-corrosion treatments. To ensure the quality of pipeline insulation and anti-corrosion, it is required that the steel pipes be descaled by sandblasting and coated with primer before being installed. Drainage pits are dug at regular intervals in the trench to pump out water, and the insulation and anti-corrosion work is carried out while pumping, thereby preventing the insulation material from becoming damp or soaked. Since the pipes flow into the tank by gravity, some of the pipes in the original design were laid in contact with the ground. For this renovation, laying the pipes in contact with the ground presents two problems: one is the accumulation of water in the pipe trenches, and the other is that the pipes being too close to the ground makes it difficult to carry out insulation and anti-corrosion treatments. Based on the actual conditions on site and the elevations indicated in the drawings, I proposed raising the entire set of dirty oil pipelines in the aromatic refining disproportionation unit. After measurements and evaluations by the design team and the workshop, approval was given for this elevation increase, which effectively solved the problems caused by the pipelines being laid close to the ground. c) The major maintenance period is short and the workload is heavy; safety, quality, and schedule all need to be ensured. This year’s maintenance will last 45 days in total, but 21 of those days will be spent in rainy weather. During the maintenance period, I was responsible for supervising the installation of pipelines and equipment for 12 projects. I actively implement the company’s philosophy and approach of \"everyone being a safety officer.\" Based on the requirements of maintenance work, I am not only responsible for the installation tasks but also take on the responsibility of ensuring the safety management of these projects. To ensure safety, our supervision department and the owner conduct regular comprehensive safety inspections at the site, and any issues found are addressed immediately. Review the large-scale equipment lifting plan, inspect the trial lift, lifting equipment, foundation, and site conditions, and provide on-site supervision throughout the entire lifting process. Daily on-site safety hazards and issues are reported to the owner at regular meetings, in order to strengthen the safety management of the construction party. To ensure quality, thorough review of drawings and approval of construction plans are carried out, along with the submission of reasonable suggestions ； Conduct inspections at equipment manufacturing stages to achieve proactive control. During that period, inspections of equipment at Liaoning Qingying Petrochemical Equipment Factory, Luoyang 725 Institute’s Shuangrui Special Equipment Factory, and XX Pressure Vessel Factory were carried out; a total of 36 various issues were identified. Seven major quality problems that could have arisen after the equipment arrived were avoided, allowing such issues to be resolved before the equipment was delivered. To maintain progress, meticulous management is adopted. On a regular basis each day, meetings are held in the workshop and with various construction units to discuss the project progress. At these meetings, the daily construction progress is reported, and it is compared with the arrangements made at the previous day’s meeting; meanwhile, the tasks for the next day’s work as well as any related coordination issues are finalized. On-site inspections were carried out at the equipment installation points that required inspection and acceptance, ensuring that inspections could be conducted at any time during installation. This not only maintained 24/7 continuity in project construction but also facilitated effective prior control over the quality of equipment installation. IV. Analysis of shortcomings in work performance a) Lack of construction experience; only the mandatory requirements outlined in standards are followed, with no practical support available. Although I have been working in the supervision industry for over two years, I believe that starting work in supervision right after graduation means a lack of practical experience in installation, and this represents a significant bottleneck for an engineer specializing in installation. I often think about what our new employees lack compared to those who have been with the company for longer. Through years of interaction and communication, I’ve realized that what we lack is not only extensive work experience but also certain fundamental differences. For example, I am familiar with the standards and know that the requirement for the levelness of a pump is \"5 millimeters vertically and 10 millimeters horizontally,\" but I have no idea what impact a lateral deviation of 0.11 mm/m or 0.15 mm/m in a pump would have on its operation. Veteran workers who have experience with installation or production are likely to know exactly what size of pump and what level of deviation can cause excessive lateral vibration in the pump, which in turn can lead to severe bearing wear over time. These things cannot be mastered merely by studying the relevant standards; one must think diligently, study hard, and ask questions frequently. By focusing on accumulating knowledge and broadening one’s knowledge base, it is possible to achieve a qualitative improvement in one’s skills. b) There is a lack of connection between theory and practice, and familiarity with basic knowledge such as refinery plant processes is lacking. Although I studied petrochemical engineering processes at school, I still lack knowledge regarding the specific processes of oil refining plants and related topics. During the supervision process, especially when communicating with the workshop or designers, a lack of familiarity with the principles of the plant’s operation directly hinders the progress of work and effective communication. In the future, one should make full use of their spare time and, relying on their professional knowledge, familiarize themselves in advance with the processes and principles of the systems they are to supervise. During my visit to the XX project, I used my free time to gather a large amount of information on DCC devices, preparing thoroughly and equipping myself with professional knowledge to address various issues that may arise during construction. c) Welding is the core part of the installation work and requires focused study*. Through extensive experience in project supervision, I have come to deeply understand the importance of welding for the installation field, whether it is related to process pipelines or static equipment. Without certain welding knowledge, one can be considered like a blind person on the job site. Due to the limitations of my major, my knowledge of welding is virtually non-existent; although I have been studying it diligently over these two years, my understanding remains superficial and lacks a systematic and comprehensive approach. In the future, I should devote more effort to areas such as the properties of metal materials, welding techniques, heat treatment, and non-destructive testing. I also hope that the company will organize training programs related to welding. V. Outlook on next year’s work plan and key priorities Time flies; the days pass by swiftly. A new year is approaching. If I count on my fingers, I’ve been working at the company for two and a half years now. I remember someone telling me that it takes three years to become proficient in engineering work. Thinking about it now, if one can become proficient in three years, it must be because they have studied hard for those three years. In the days to come, I must have the spirit of \"proving my worth without needing to be urged,\" working hard and diligently, accumulating experience through practice, and learning knowledge through it. As a knowledge-intensive company, only by equipping ourselves with knowledge can our firm become strong; let’s work together to create a brighter future.
