Arrangement method of ship desulfurization washing water pipeline

The invention relates to a ship desulfurization washing water pipeline arrangement method which comprises the following steps: S1, inspecting an original ship, scanning an original ship structure, andgenerating a three-dimensional point cloud database according to scanning parameters of the original ship structure; S2, performing retrograde modeling; S3, interactive design of the washing water pipeline is carried out in combination with a point cloud model obtained through original ship retrograde modeling; S4, carrying out static interference check on the washing water pipeline; S5, dividingpipe sections of the washing water pipelines; S6, performing dynamic simulation; S7, outputting a final drawing and carrying out prefabrication work of the washing water pipeline according to the drawing; and S8, lifting and mounting the desulfurization washing water pipeline. By adopting a digital arrangement method, digital means are adopted for surveying and mapping an original ship structureand designing a washing wat
