[Haichuan Overseas Engineering] Completion of the capping of the 123.4-meter-high urea plant granulation tower for the PUSRI-IIIB project in Indonesia

On December 31, 2025, in Palembang, Indonesia, a 123.4-meter-tall reinforced concrete tower was officially completed, having withstood the scorching sun and harsh conditions. The granulation tower of the urea plant in the PUSRI-IIIB project, constructed by China National Chemical Engineering Corporation’s 11th Construction Company, resembles a silver sword that pierces the sky over the equator, becoming a new industrial landmark for this port city. This is not merely the completion of a construction milestone; it is also the victory of an overseas challenge that required overcoming great distances, honing expertise, and working together toward common goals. It embodies the wisdom and hard work of the builders from China and Indonesia; it witnesses the steady progress made by China National Chemical Engineering Corporation in expanding its operations overseas, and it represents yet another remarkable chapter in the story of \"Chinese construction\" within the Belt and Road Initiative. Let’s go back to the early stages of the project. The project team for the 11th Chemical Construction Project is faced with a highly challenging task: the construction area is located in a marshy region of an old factory site, where more than 200 old piles are scattered underground, acting like hidden \"bones\" that make foundation treatment extremely complex ； The work site is narrow, with frequent concurrent operations, resulting in significant pressure on safety management. A greater challenge comes from “people”. In the slip-form construction of this project, 99% of the workers are Indonesian. Differences in language communication, work habits, and technical understanding, coupled with unstable local concrete supply and the severe impact of the hot and rainy climate on the construction process, result in a geometric increase in the difficulties associated with project organization and quality control. “The harder the situation, the more we need to demonstrate our professionalism and responsibility. ”The project manager was firm in his words at the mobilization meeting. No retreat, only the call to move forward. The technical team began working day and night to develop slip-form construction methods suitable for local conditions, the local management team quickly established bridges for cross-cultural communication, while the construction team set about preparing a detailed 24-hour shift schedule. An overseas campaign against time, environment, and complex conditions has quietly begun. Sliding form construction in granulation towers is a millimeter-level “vertical marathon”. The formwork must rise continuously at a nearly uniform rate as the concrete is poured; any slight deviation or loss of control over the setting time can result in all previous efforts being wasted. The sun at the equator is scorching hot; the rebar on the high-altitude platform becomes unbearably hot to the touch. Chinese engineers stood side by side with Indonesian workers, their heavy work uniforms soaked with sweat. To ensure continuous operation, the project promptly adopted a \"24-hour two-shift system.\" During the day, they tied things tightly in the heat wave and monitored closely ； At night, searchlights cut through the darkness; engineers work round the clock, using dim light and precise instruments to monitor every vibration and every inch of progress. The real technical showdown takes place in the middle stage of tower climbing. High temperatures cause fluctuations in the properties of concrete, and the formwork shows signs of slight distortion. “It is essential to ensure perfect verticality! ”The technical task force was called upon to take on this challenge; they stayed at the site, worked together with the laboratory to conduct dozens of adjustments and tests, introduced a high-precision laser positioning system for real-time correction, and innovatively added an adjustable micro-support system at key stages. After several consecutive sleepless nights, an encouraging message finally came over the radio: “The data is stable, and the verticality is perfect!” ”——Chinese technology has solved the balance challenge of \"high-altitude ballet\" at overseas construction sites.
