CBD petrol stations in urban areas;

Newly-built petrol stations (tanks need to be rebuilt according to the impermeability requirements);

Petrol stations with tanks buried under canopies and driveways;

Special geological or environmental risk petrol stations;

These petrol stations have special locations, high sales volume, and are unable to carry out large-volume civil construction to replace tanks. If they are shut down for renovation and re-tanking, there are problems such as high renovation costs, wasted investment, and high safety risks.

As the historical capital of China, Beijing has always been at the forefront of environmental protection. As early as before the promulgation of the "Ten Articles on Water", Beijing had already started the process of upgrading the buried tanks of petrol stations, but the urban construction of Beijing has gone through a long process, during which there are very many legacy problems due to the limitations of the environment and the times.

Beijing Xuanwumen Petrol Station, located directly above Subway Line 2, has the main Xuanwumen East Street parallel to it on its north side; the underground vent (with a floor area of about 50 square meters, a Type III protected building) is about 12 meters to the west; the green belt is on the east side of the petrol station; a residential building (a Type II protected building) is about 25 meters to the south, separated from the auxiliary road; the station area has an entrance to the north and south of the western end of the station area, and an exit and an exit to the north and south of the eastern end of the station area. There is a petrol station entrance at the west end of the station area from north to south, and an exit at the east end of the station area from north to south, which is connected to the main and auxiliary roads of Xuanwumen East Street. Not only is the surrounding terrain complex, but with just three 30-meter tanks, the station sells more than 10,000 tonnes of fuel and has a busy daily business.

Due to the above factors, Beijing Xuanwumen Petrol Filling Station faced the great challenge of upgrading buried tanks.

The Solution

Oket undertook the reconstruction of the buried tanks at the station with its excellent construction strength and the world's leading PHOENIX System double-layer composite liner tank reconstruction technology.

With the Phoenix system, single-layer steel buried tanks at petrol stations can be upgraded to double-layer tanks with a complete double-layer all-composite structure without moving the existing buried tanks or damaging the surrounding area and structures. The upgraded tanks have a complete intermediate layer structure and are fitted as standard with the industry's leading liquid media leakage detection system, which provides 360° active leakage detection without dead angle.

In the construction of the Phoenix system, various difficulties may be encountered: for example, if there is seepage leakage on the tank wall, the Phoenix system can find the leakage point and repair it with special technology; for example, if the tank head is not standard, the Phoenix system can transition the joints to achieve seamless connection of the tank liner; for example, as in the case of the Xuanwumen petrol station in Beijing, not only were the drawings of the station lost, but also it could not be surveyed by conventional means due to the impact of the underground and the surrounding structures. For example, like Xuanwumen gas station in Beijing, not only the construction drawings were lost, but also due to the influence of the subway and the surrounding structures, it was impossible to survey the specific condition of the tanks by conventional means, but Oket could, by giving full play to its own accumulation of "Remote Volumetric Tables Auto-Calibration" technology, carry out inverse modeling on the measured tank volume tables, and invertedly push out the specific dimensions of the tanks, which also included the type of reinforcement of the tanks, whether or not seepage leakage existed, and where the deformation existed. The details are all at a glance, providing a theoretical basis for the preliminary construction and programme development of the station's Phoenix system, and helping it to complete the tank nirvana. For example, there are various support structures in the tanks, and the Phoenix system is able to deal with them by various means, such as covering or reconstructing, to provide solutions.

Ausco Sino-Italian? Phoenix System has formulated and implemented perfect construction programmes, risk control procedures, emergency plans and other specifications, and has implemented traceable quality and risk control measures throughout the entire process from the arrival of raw materials and equipment to the completion and acceptance of the project.

The double-layer composite lining technology is relatively widely used in developed countries, and therefore has formed a complete system of standard requirements, of which ULC/ORD-C58.4 is undoubtedly the most authoritative one. Oket Phoenix system is the only lining system in the world that has passed the UL standard and can be used for buried tanks of all known oil products.

Customer Value

At present, Oket The Phoenix system has been applied in 24 provinces, autonomous regions and municipalities directly under the central government, with more than 400 petrol stations. The customer range covers Sinopec, PetroChina, CNOOC, Sinopec Senmei, Social Group, etc. The market share is the first in China, which is fully recognised by the market. Whether we can solve the actual problems for our customers has always been the standard for Qingdao AOKE and AOKE Zhongyi to judge their own technical strength; how to better solve the actual problems for our customers through the continuous innovation and mutual integration of technology is more the direction and goal we have been working hard for a long time. We not only have a perfect management system, but also can guarantee the quality of the liner tanks and the safety of the site.
