Abstract
An underwater mobile inspection apparatus is capable of inspecting a subsea pipeline (inspection object) while cruising. The underwater mobile inspection apparatus includes: a cruising body configured to submerge under water and cruise along the inspection object in such a manner as not to come into contact with the subsea pipeline; a first movable arm provided on the cruising body; an inspection tool unit for use in inspecting the subsea pipeline, the inspection tool unit being provided on the first movable arm; and a controller configured to, when the cruising body cruises along the subsea pipeline in such a manner as not to come into contact with the subsea pipeline, operate the first movable arm to move the inspection tool unit, such that a positional relationship of the inspection tool unit with the subsea pipeline becomes a predetermined target positional relationship.
