Recently, the second phase of the liquefaction storage project in Dongjiakou Port Area of Qingdao Port has completed the heat treatment of 12 spherical tanks, which provides preconditions for the hydraulic test of spherical tanks and lays a solid foundation for the construction of the project.
The new low-temperature tank group of the second phase of the liquefaction storage project in Dongjiakou port area includes 2 50,000-square-meter low-temperature atmospheric bimetallic full-capacity tanks, and the spherical tank group includes 8 3,000-square-meter normal temperature pressure spherical tanks, 4 2,000-square-meter normal temperature pressure spherical tanks, and ancillary facilities.
The heat treatment temperature of the spherical tank has a great influence on the structure and properties of the material, and too high or too low a temperature will have an adverse effect.
In order to do a good job in temperature control and ensure the quality of the project, at the critical moment of spherical tank heat treatment, the project team members worked day and night to ensure that every detail reached the best state. Through on-site monitoring and intelligent monitoring, the precise control of the heat treatment link of the spherical tank is realized, which ensures the safety and quality of the main body of the spherical tank after heat treatment, and lays the foundation for striving for the "AAAA National Chemical Industry Quality Engineering Award".
Behind the steady pace of project construction is the continuous improvement of the level of refinement of project management. The project department adheres to the "morning meeting" at 7 o'clock every day and establishes a standardized process of "morning meeting". After the daytime work, organize the construction and supervision to hold a night shift scheduling meeting, summarize and reflect on the situation of the day, analyze the problems, correct deviations in time, and arrange the next plan. The project adheres to the principle of "there are members of the project department when there is construction", and is on duty 24 hours a day and night, and since the start of construction, the project has achieved "zero" safety production accidents.
Quality is the "lifeline" of project construction. In order to ensure the quality of construction, the project department manages the site block, divides the construction area, constructs independently between the areas, does not cross each other, sets up the regional person in charge, and the project department organizes PMC, supervision, general contractor, and subcontracting management personnel to take the lead in keeping an eye on it, giving full play to the role of management personnel at all levels, and moving towards the goal of AAAAA level green construction site of China Chemical Industry Association. In order to ensure the quality of welding, after the welding of the spherical tank on site is completed, the TOFD100% test is carried out first, and after the test is completed, 100% ultrasonic and 100% magnetic particle are tested to ensure that the quality pass rate of each weld reaches "3 100%". In the project inspection, the overall pass rate of TOFD is 99.4%, and the highest pass rate is T-122C, and the pass rate is 99.8%, and the project construction indicators are completed with high quality and high standards.
At present, the project cast-in-place pile construction has completed a total of 1469, a total of 90% of the total completion, in order to ensure the progress of cast-in-place pile construction, the site takes 24-hour operation, increases night shift construction, project department members day and night to keep an eye on, strict safety, quality. At present, the project has met the application conditions for the National Quality Engineering Award.
