摘要:
An object is to prevent damage to an inspection object such as a subsea structure, the damage being due to receiving force based on the mass of a cruising body, and to improve the quality of various work, including an inspection of the inspection object. An underwater mobile inspection apparatus 11 is capable of inspecting a subsea pipeline (inspection object) 13 while cruising. The underwater mobile inspection apparatus 11 includes: a cruising body 14 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 13; a first movable arm 16 provided on the cruising body 14; an inspection tool unit 17 for use in inspecting the subsea pipeline 13, the inspection tool unit 17 being provided on the first movable arm 16; and a controller configured to, when the cruising body 14 cruises along the subsea pipeline 13 in such a manner as not to come into contact with the subsea pipeline 13, operate the first movable arm 16 to move the inspection tool unit 17, such that a positional relationship of the inspection tool unit 17 with the subsea pipeline 13 becomes a predetermined target positional relationship.

摘要:
A fluid of high specific gravity and viscosity stored in a desired one of tanks can be quickly transferred to the other tank with high flow rate accuracy. The present invention includes: first and second tanks (13) and (14) each configured to store a fluid (12) containing fine powder; a communication pipe (15) through which the first and second tanks (13) and (14) communicate with each other; and a transfer portion (16) configured to transfer the fluid (12) stored in a desired one of the first and second tanks to the other tank. Each of the tanks (13) and (14) includes a first chamber (19) and a second chamber (20) that are separated by a deformable dividing wall (18). Each of the first chambers (19) stores an incompressible fluid (17), and each of the second chambers (20) stores the fluid (12) having higher specific gravity and viscosity than the incompressible fluid (17). The second chambers (20) of the first and second tanks communicate with each other through the communication pipe (15). When the incompressible fluid (17) is supplied to the desired first chamber (19), the transfer portion (16) can discharge the incompressible fluid (17) from the other first chamber (19).
