Recently, good news came from the Pipeline Integrity Department of the Resource Sharing Center at Daqing Oilfield Engineering Construction Company. The 4-member team it assembled successfully completed the task assigned to them in the 2025 defect ring weld Type B sleeve repair project carried out by the West-East Gas Transmission Corporation’s Jiangsu, Zhejiang, and Shanghai branch. Thanks to their excellent execution skills and problem-solving abilities, they not only passed the inspection successfully but also received high praise from the client, marking this as a successful first step for the center in expanding its operations in new markets. 　　As the center’s first construction project launched in the market, this project bears the important mission of exploring market-based operation models and establishing a professional brand image. Upon arriving at the construction site in Wuxi City, Jiangsu Province, on June 30, the project team got straight to work. In just 3 days, they efficiently completed all the preliminary preparations, including submitting applications for site access, arranging personnel, bringing in mechanical equipment, and preparing construction materials, thus laying a solid foundation for the smooth commencement of the project. 　　This construction task involves performing B-type sleeve repairs on the defective ring welds of the pipelines under the jurisdiction of the Jiangsu-Zhejiang-Shanghai Gas Transmission Branch. The work encompasses the entire process, including ring weld positioning, coordination for temporary land use, excavation of work pits, safety measures, welding operations, anti-corrosion and insulation treatments, as well as landscape restoration. Faced with the dual pressures of a tight schedule and heavy workload, the team members stepped up to the challenge and progressed steadily in strict accordance with the construction plan: from July 3rd to 5th, they completed the excavation of 539 cubic meters of soil, creating the conditions necessary for subsequent work; on the 6th, they quickly set up protective shelters to establish a safety barrier for the construction process; on the 7th, they precisely carried out equipment calibration and sleeve alignment to ensure perfection in the welding process. 　　Since the pipelines in use could not have their flow stopped, from the 8th to the 10th, the team worked around the clock, carrying out welding operations for three consecutive days under scorching heat. At that time, the temperature at the construction site was over 40 degrees, with intense heat waves on the surface. The team members stayed at their posts despite the scorching heat, overseeing welding operations, conducting gas tests, checking safety procedures, and coordinating the work on site. One task after another was carried out in an orderly manner, with their work clothes soaked with sweat. Their voices became hoarse yet remained strong, and their steps grew heavier yet they never stopped. They demonstrated responsibility and commitment through their perseverance, and ensured the safe and smooth progress of the construction work through their hard work. Subsequently, unmanned monitoring was carried out from the 11th to the 12th; anti-corrosion and insulation work was advanced efficiently on the 13th; and soil backfilling was completed in its entirety on the 14th. The entire construction process was well-coordinated with a fast pace, enabling the project deadline to be met ahead of schedule. 　　During the construction period, the challenges faced were far beyond imagination. Not only does one have to deal with the extreme physical strain caused by continuous high temperatures above 40 degrees, but exposure to the sun during outdoor construction can also lead to skin peeling, while repeated attacks from mosquitoes make it difficult to find peace. Moreover, it is necessary to overcome the numerous challenges associated with a team entering a new market for the first time and managing a project as the general contractor – from coordinating procedures with the client, securing temporary land, to ensuring quality control throughout the construction process and fully fulfilling safety responsibilities; every aspect requires starting from scratch and overcoming difficulties one by one. Yet this team of just 4 people has always adhered to the principle of \"safety first, quality foremost,\" strictly following all operational standards. They work hard under the scorching sun during the day, and at night they review the work done that day and plan for the next day’s tasks. The personnel in the back-office also play a vital role, providing strong support in areas such as preparing documentation, checking the qualifications of staff, and re-inspecting equipment and materials. Through the joint efforts of the entire project team, it is ensured that every step of the process meets the required standards, and professionalism and perseverance are used to overcome one challenge after another. 　　Thanks to their solid professional skills and relentless dedication, the project team completed all construction tasks on schedule. Upon inspection by the client, all criteria related to project quality and safety management met the required standards. The client fully recognized the team’s high level of efficiency and excellence in construction under extreme conditions, believing that it \"proved with its performance the capabilities of a professional team to tackle challenging tasks.\" 　　After achieving success in the first attempt, the project team did not stop there. At present, they have taken the initiative to engage with the client party and conducted on-site inspections at the construction site. By drawing on the proven experience gained from this project, they are refining their bidding proposals for future projects, with the aim of continuing to win bids for subsequent tasks related to the inspection and management of quality risks in the circumferential welds of the West-East Gas Pipeline project. This will contribute to the company’s high-quality development as well as the expansion of the center’s market presence outside its home region.
