In an underwater operation system of the present application, when an exploration operation is started, a processing device: acquires, from an acoustic positioning system, the relative position of an underwater vehicle with respect to a surface vessel; calculates the position of the underwater vehicle on the basis of the acquired relative position; and when there is an overlap between a measurement error region centered on the calculated position of the underwater vehicle, and an expected pipelaying region for a pipeline extending in a prescribed direction, causes the underwater vehicle to move to a position where there is no overlap between the measurement error region and the expected pipelaying region, and then causes the underwater vehicle to perform a crossing detection in which the underwater vehicle detects the presence or absence of a pipeline while crossing the expected pipelaying region.
