【Thorough Discussion on Maintenance Work in Haichuan】The \"Three Transparency\" maintenance approach proposed by a certain refining and chemical company – what are everyone’s thoughts on it?

I saw in the news that a certain refining company proposed a \"Three Brights\" maintenance approach – what are your thoughts on it? ——–－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－ This November, the aromatic compounds processing unit at XX Refining and Chemicals underwent its first major maintenance campaign. Given the heavy workload and high intensity of this task, as well as the fact that most employees were participating in such a large-scale maintenance effort for the first time, the company’s Aromatic Compounds Department took a comprehensive approach, implementing the “Three Transparencies” method: transparency regarding the workload, transparency regarding the responsible persons, and transparency regarding the progress of the work, thereby ensuring that the maintenance tasks were carried out in an orderly manner. First, clarify the workload. Before shutting down for maintenance, the Aromatics Department conducts simulations for each phase of shutdown, maintenance, and restart, so as to have a clear understanding of the overall workload during the maintenance period. Adjust the work teams as appropriate based on the workload at each stage to optimize personnel allocation. During the shutdown period, tasks were relatively concentrated, so the department merged the four shifts into two larger shifts; four shift leaders took turns serving as the main and deputy supervisors of these larger shifts, adopting a two-shift rotation system. The team established several shutdown teams led by key members, assigning specific tasks based on each team’s specialized skills, so that everyone could focus on their area of expertise. Each group and each class presents their daily workload at the daily meeting, summarizes the achievements promptly, identifies problems, and then works together to come up with solutions to those problems. Second, identify the person responsible for the work. In addition to the tasks assigned uniformly by the department, the four teams are responsible for specific areas within the plant; each team leader acts as the person in charge of that area. The work responsibilities of these team leaders are supervised and guided by the unit managers in terms of safety, process, and equipment aspects ； The team selects skilled operators with extensive work experience and a strong sense of responsibility to serve as group leaders, clearly defining their responsibilities and powers; the work of each group is inspected, supervised, and verified by the team leader. The work responsibilities of team members, shift leaders, and unit managers are visualized and structured in a grid format; for special tasks, confirmation and signatures from the operator, shift leader, and manager are required to ensure closed-loop management. Third, clarify the work progress. The inspection, repair, and modification of equipment is a systematic project; if any step in this process is not properly managed, it can affect the overall progress. To this end, each team further refines the network diagram showing the shutdown of the facility; they list on the wall the names of the tasks related to maintenance, construction, and renovation, the duration required for these tasks, the HSE requirements, the contractors involved, and the persons in charge. They evaluate and compare one another’s work, making it clear at a glance how much time is needed for each type of task. Before the daily shift change, the progress of tasks completed that day is recorded in charts, allowing teams to stay informed about the progress of work in their respective areas and thus ensuring the overall schedule for maintaining the facility. To date, aside from the p-xylene unit which is still under shutdown for purging, units such as aromatic extraction and isomerization have been successfully handed over for maintenance, with all operations completed ahead of the originally scheduled deadlines.
