The mechanical completion of the LNG F-6004 storage tank repair project carried out by Global Southeast Asia Company in Indonesia has been successfully achieved. Recently, the company received the mechanical completion certificate issued by the owner of this LNG storage tank repair project, which belongs to **Indonesia Natural Gas Company. This marks the successful conclusion of the construction phase of this project, laying a solid foundation for the owner to carry out formal cold-start testing and put the facility into operation. The LNG F-6004 storage tank repair project in Indonesia was the company’s first initiative in the Indonesian market to carry out a project in a consortium format with PGASOL. This tank is one of the double-walled, single-volume tanks built at Indonesia’s Arun LNG terminal in 1978; it has an effective storage capacity of 127,000 cubic meters. It was put out of use after a leak was detected in its bottom plate in 2004. Since the project was launched on May 9, 2024, in the face of the harsh local climate featuring high temperatures and humidity, complex and outdated site conditions, as well as stringent standard requirements, the project team effectively leveraged the company’s extensive experience in LNG technology and international project management. By working together with local Indonesian partners to complement each other’s strengths and share risks, they overcame numerous technical and managerial challenges, ensuring the smooth progress of the project. For the first time, this project successfully carried out large-scale film welding and isolation work in the 1.2-meter-wide annular gap around the tank wall, creating a complete secondary sealing barrier for the bottom plate; this greatly improved the sealing integrity and safety margin of the old storage tanks. Through staged drying, vacuum extraction, and nitrogen purging, the inerting drying parameters met requirements significantly better than those specified, ensuring optimal airtightness and dryness of the storage tank and providing a reliable foundation for subsequent liquid filling. The high-quality completion of the mechanical work has laid a solid foundation for the F-6004 storage tank to be put back into operation in a brand-new condition. This project represents not only a strategic breakthrough for Global Company in entering the Indonesian market, but also a practical example of the concept of win-win cooperation under the Belt and Road Initiative. It has successfully explored a new approach to improving project execution efficiency and value creation through deep local collaboration, thereby providing valuable experience for Global Company to further expand its activities in overseas energy infrastructure projects and enhancing the influence of its brand.
