[0008] S4: Compare the actual model generated by the image modeling with the design model.

[0009] Further: In step S1, the A60 pipelines in each chamber of the ship are scanned by a drone.

[0010] Further: In step S1, the A60 pipelines in each chamber of the ship are scanned by a handheld imager.

[0011] Further: in step S1, a sticker is attached to the outside of the A60 pipeline, and a logo is printed on the sticker.

[0012] Furthermore: the logo can be reflective.

[0013] Further: the logo is printed with directions.

[0014] Furthermore: the identification may be of multiple types, for distinguishing different system pipelines.

[0015] Further: In step S1, each chamber of the ship includes a garage or a storage chamber.

[0016] Further: in step S4, the actual model generated by the image modeling is manually compared with the design model.

[0017] Further: in step S4, the computer compares the actual model generated by the image modeling with the design model.
