Method of inspecting a vessel including obtaining a first data set (14, 114) associated with a first surface (340) of at least a portion of the vessel. The first data set (14, 114) is obtained with laser scanning A model or simulation (12, 112, 212, 312) indicative of the first surface (340) is generated in dependence on the obtained first data set (14, 114). A property of the portion of the vessel is determined in dependence on the generated model or simulation (12, 112, 212, 312).
