Description

Technical Field

[0002] As a core facility for liquefied natural gas (LNG) storage, vertical membrane tanks are widely used in energy storage projects due to their significant advantages, including high space utilization, manageable construction costs, and long service life. Precise baseline definition is crucial within the internal tank system of a vertical membrane tank. Its accuracy directly impacts the overall performance and safe operation of the tank, and is a key technical step in ensuring its stable function.

[0003] After searching, Chinese invention patent application CN115265503A discloses a method for marking the baseline of a membrane tank, which includes: S1. Theoretical model: input theoretical coordinates and input theoretical coordinates into POLYWORKS to establish a theoretical model of a membrane tank-in-tank; S2. Actual model: actual coordinates are obtained by actual measurement, and actual coordinates are input into POLYWORKS to establish an actual model of a membrane tank-in-tank; S3. Model fitting and marking: fit the theoretical model of the membrane tank-in-tank with the actual model, determine the actual plane and actual angle surface in the actual model of the membrane tank-in-tank according to the theoretical plane and theoretical angle surface in the theoretical model of the membrane tank-in-tank, and mark the tank wall baseline and tank bottom baseline in the constructed membrane tank-in-tank accordingly; S4. Baseline inspection: after the tank wall baseline and tank bottom baseline are marked, the tank bottom baseline and tank top baseline are inspected. After the tank bottom baseline and tank top baseline inspection meet the requirements, the marking of the membrane tank baseline is completed.

[0004] However, when the tank deforms and the baseline needs to be adjusted, the above solution relies on POLYWORKS software to complete the fitting of the actual model and the theoretical model, which requires re-measurement and fitting, greatly affecting the efficiency of the overall adjustment.

[0049] (1) The vertical tank baseline deformation adjustment scheme designed by the present invention is based on the preliminary update of corner points under vertical geometric constraints, and then introduces the constraints of wall verticality, opposite wall verticality and adjacent wall centerline offset distance difference to adjust the top corner points. Then, linear regression fitting is performed based on the bottom mark point of the wall, the bottom mark point of the opposite wall and the coordinates of the bottom circle center. After intersecting with the bottom edge, the wall mark point is re-determined, and the bottom mark point and corner point are adjusted again based on the distance difference constraint. The overall baseline data adjustment is based on the actual engineering measurement data and actual engineering constraints. By using multiple constraints to judge and adjust, the overall process can generate the mark point and corner point data that meet the requirements, avoiding multiple fitting modeling of the actual model and the theoretical model. The baseline deformation adjustment process is more efficient, convenient and accurate.

[0050] (2) In the initial stage of the present invention, rays are drawn from the center of the bottom circle along the direction of the angle bisector, and the intersection points of the rays with each edge of the bottom polygon are recorded as marking points. The bottom corner points of the wall are updated according to the marking points and the vertical geometric constraints, and the overall corner point error is first reduced to a smaller range to facilitate subsequent fine-tuning and optimization.

[0051] (3) The present invention uses the angle between the vector of the bottom marking point and the corresponding top marking point and the basis vector to measure the verticality of the wall. Through vector dot product calculation, the verticality is accurately quantified to achieve engineering implementation, which facilitates the subsequent more convenient and rapid implementation of offset constraint judgment.

[0052] (4) The present invention introduces a difference constraint on the centerline offset distance of a wall or adjacent walls. When calculating the centerline offset distance of a wall, a mixed product is constructed using the wall marker points, the bottom circle points, and the basis vectors. The centerline offset distance is accurately quantified by relying on mathematical geometric constraints. BRIEF DESCRIPTION OF THE DRAWINGS
