On October 20, the integrity tests of the 16 spherical tanks in the olefin tank area of the Qinghai Damei EPC tank farm project, which were carried out by Sinopec Nanjing Engineering Storage and Transportation Engineering Branch, were successfully completed. This marks the full completion of the installation of the main structures of these 16 spherical tanks as well as their safety accessories in this tank area, and the project has now entered the final stage of anti-corrosion and insulation work. The Qinghai Damei EPC tank farm project makes full use of the advantages of integrated general contracting, ensuring seamless integration of design, procurement, and construction. It also works together with the company’s procurement and design departments to maintain thorough communication with the manufacturers of components such as spherical tank segments and lifting lugs, as well as to carry out proper technical preparations. In accordance with the on-site construction plan, the procurement department closely monitors the production schedule of the spherical shell plate manufacturers to ensure that the plates arrive at the construction site on time. During the ball tank welding phase, the company’s design department works together with the project team to carry out coordinated planning and collaborative efforts, thereby preparing the work area for the ball tank welding. At the same time, the company’s procurement department, taking into account past issues where the safety accessories for spherical tanks hindered the integrity tests of these tanks, procured the necessary safety accessories in advance, thus laying the foundation for conducting the integrity tests. All 16 spherical tanks in the olefin tank farm were assembled by May 28, and welding on all of them was completed by June 30. After the welding of the spherical tank was completed, the project team overcame the impact of continuous rainy weather by implementing effective rainproof measures. This ensured that all heat treatment tasks were finished on September 4, and all hydrostatic testing was completed on September 26. By October 20, all tests for the tank’s airtightness had been carried out, enabling the installation of the spherical tank to be completed safely, with high quality and efficiency. At the same time, during routine construction activities, the project team maintains a high level of vigilance regarding the welding quality of the spherical tanks. By focusing on every detail, they ensure strict quality control, identify the factors that contribute to high-quality construction, and closely monitor the welding process, the welding environment, as well as the use of welding materials. Responsibilities are assigned to specific welding personnel, and the welds completed are inspected one by one by technical quality control staff to eliminate any potential risks. The Qinghai Damei EPC tank farm project made full use of the advantages of general contracting management, demonstrating the value of the company’s EPC integrated management approach. Through coordinated operations, the project progressed steadily, and the construction of the spherical tanks was completed with excellent quality, thus becoming a showcase for the company’s capabilities.

It’s already snowing. What’s the use of CCCC now? It can’t do anything anymore; the electrical and instrumentation systems will need to be recalibrated again next spring.

As can be seen from Photo 3, neither the main facility nor the power plant has been completed yet.

In domestic projects, the concept of mechanical completion (MC) basically does not exist. For this tank farm, the political significance associated with it, as perceived by CCCC, seems to outweigh its actual practical value. Due to the severe cold in winter, the electrical and instrumentation systems either get damaged by freezing or get stolen; once spring arrives, it will be necessary to reinstall them and carry out recommissioning work, which is really not very meaningful.

On the morning of November 3, the air compressor station for the comprehensive utilization of exhaust gases from Qinghai Damei Coal Industry to produce olefins was successfully handed over in this project, which was constructed under the general contract by Baosteel Engineering Company. The main works of the project will be completed in phases by CCCC; it is planned that all will be finished by December 31, 2018, with operation starting in the first half of 2019. The olefin production project based on the comprehensive utilization of exhaust gases from Qinghai Damei Coal Industry utilizes some of the regional methanol resources derived from projects that produce methanol from exhaust gases generated in the area’s smelting operations; the project does not directly use the exhaust gases from these smelting operations to produce methanol. The methanol used as raw material for this project comes from Qinghai Guilu Chemical Co., Ltd. (1 million tons per year), Western Petrochemical Co., Ltd. (600,000 tons per year), and the Golmud Refinery of CNPC’s Qinghai Oilfield (300,000 tons per year); agreements for the supply of methanol have been signed with all of these parties. The Comprehensive Utilization of Exhaust Gases from Qinghai Damei Coal Industry for Olefin Production Project (hereinafter referred to as the “Project”) is located in the Western Area of Ganhe Industrial Park, Xining Economic and Technological Development Zone, Qinghai Province. With a total investment of 12.77 billion yuan, the project officially commenced construction on March 23. It is a key construction project during Qinghai Province’s 13th Five-Year Plan period, and it represents the fifth project launched under the plans of the Qinghai Provincial Party Committee and the provincial government to upgrade the chemical industry to a value of 100 billion yuan. On August 6, a project progress analysis and construction advancement meeting was held in Xining, with the requirement to ensure that the project achieves its goal of high-standard completion by December 31, 2018. On September 30, all installation work for Project 110kV Huanyu Substation and the external transmission lines was completed, and the project was handed over successfully – this marked the first completion milestone for this project. On November 2, the main structure of the project’s polyethylene plant passed the final acceptance test in one go.

According to the Qinghai Provincial State-owned Assets Administration Committee, on the morning of November 3, 2018, the main component of the olefin production project resulting from the comprehensive utilization of exhaust gases at Qinghai Damei Coal Industry Co., Ltd. – namely the plant’s air compression station – was successfully completed. The construction scale of the comprehensive utilization of exhaust gases from Qinghai Damei Coal Industry for olefin production is 1.8 million tons per year of methanol-to-olefins, 300,000 tons per year of polyethylene, and 400,000 tons per year of polypropylene. Construction began in March 2017. All are scheduled to be completed by December 31, 2018, and put into operation in the first half of 2019.

On November 30, the plant-wide warehouse of the Qinghai Damei project, constructed by the Fifth Construction Company of Sinopec Refining & Chemical Engineering Group, was handed over to the client in accordance with high standards, marking the achievement of another major milestone in the construction of the Damei project. At the handover ceremony, Xiao Wancai, deputy general manager of Qinghai Damei Coal Industry Co., Ltd., gave full recognition to Wujian Company’s work in managing construction safety, quality, and schedule, and expressed high praise for the company’s ability to complete the construction tasks to high standards.
