An underwater mobile inspection apparatus capable of inspecting an inspection object on a seafloor while cruising includes a cruising body configured to submerge under-water and cruise along the inspection object so as to not come into contact with the inspection object, a first movable arm provided on the cruising-body, and an inspection tool unit provided on the first movable arm and including at least one of an image-capturing camera for use in visually inspecting the inspection object and a device configured to inspect a wall thickness of the inspection object by using an ultrasonic wave. A controller is configured to, when the cruising-body cruises along the inspection object so as to not come into contact with the inspection object, operate the first movable arm to move the inspection tool unit, such that a positional relationship of the inspection tool unit with the inspection object becomes a predetermined target positional relationship.

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.
