In 2023, Caspian Engineering Solutions successfully carried out extensive technical works related to the refurbishment of tanks No. 501 and 503 located at the Heydar Aliyev Oil Refinery. The main objective of the project was to dismantle the tanks that had been in service for many years and no longer met technical requirements, install new tanks that comply with modern standards, and upgrade the associated technological infrastructure of the tanks.

During the initial phase, the existing tank structures were completely dismantled in full compliance with technical safety regulations. Alongside the dismantling, site cleaning and restoration activities were also conducted. Subsequently, the construction of two new tanks, each with a capacity of 2,000 cubic meters, was commenced according to the technical drawings of the project. The newly installed tanks were manufactured using high-quality materials, and the assembly process was carried out under strict technical supervision. Weld seams, dimensional accuracy, and strength parameters were inspected in accordance with international standards, and the tanks were coated with special corrosion-resistant paints to ensure long-term protection.

To provide technical maintenance and safe access to the tanks, metal platforms and staircases were fabricated and installed within the scope of the project. These metal structures, designed according to the specified layout, weighed nearly six tons in total. The structures underwent sandblasting, followed by application of specialized coatings to meet technical specifications, and were finally installed on-site. Both aesthetic considerations and durability were key factors throughout this process.

Ensuring the technological safety of the tanks was further addressed by refurbishing the fire protection systems. A total of 200 meters of fire water piping serving both tanks were renovated, defective sections replaced, and the system was pressure tested to confirm leak-tightness and readiness for operation.

All these works were completed within a period of five months. Throughout the project, both construction and quality control processes were managed by Caspian Engineering Solutions’ team of qualified engineers, with full adherence to quality, safety, and international standards. The successful completion of this project once again demonstrated our company’s professional capacity and organizational capability in implementing complex technical solutions for large-scale industrial facilities.
