Calculation and Analysis of Ship Dock Block Layout and Key Points of Inspection based on Computer Simulation

Ship docking maintenance is an important link to ensure the integrity of underwater equipment. Full consideration should be given to the layout of dock block before docking, which is related to the structural safety and overall stability of the ship. Accuracy of dock block layout is an important guarantee for docking and working safety of a ship. According to the type, the dock blocks can be divided into single dock, double dock and triple dock. Dock block type selection and lay out position shall be in accordance with ship line. The dock block layout scheme can be firstly calculated by computer technology for the weight distribution of the structure of the whole ship. Then the finite element analysis is carried out and the layout scheme is proposed based on the previous experience. The key parts and specific parts are mainly calculated and analyzed, and the locating datum, spacing, dock line and dock type are detailed analyzed to continuously optimize the dock block layout scheme. Combined with the practical experience of engineering, this paper describes the key inspection items of ship dock block layout, including dock block layout drawing, dock block layout and sitting block. The suitable layouts of various types of dock blocks are calculated and analyzed, and the calculation results and key points of inspection are analyzed in detail. This is of guiding significance to the work of shipping in and out of the dock.
