A method comprising scanning at least one portion a hull of a vessel positioned below a waterline while the vessel is floating in water. The method further comprises generating multi-dimensional scans of the at least one portion of the hull based on data acquired during the scanning, generating a 3-dimensional (3D) model of the at least one portion of the hull, analyzing the 3D model to identify one or more features of the hull of the vessel below the waterline, generating docking information for drydocking the vessel based on the one or more features of the hull, and identifying, based on the generated docking information, a docking plan for supporting the vessel when the vessel is supported out of the water. The method further comprises outputting instructions to dry dock the vessel.
