A remotely operated vehicle (ROV) compatible photovoltaic powered cathodic protection (CP) probe can measure voltage potential of subsea structures. In an embodiment, the CP's meter is integrated and able to send CP data topside. The CP meter's compact display module also houses the telemetry board to send CP readings, via an ROV serial, topside. The CP probe does not require a battery and can be used standalone or connected through an ROV to topside logging and display. Further, the CP probe can monitor a plurality of CP voltages and other conditions such as an electrical field gradient.

An underwater mobile inspection apparatus capable of inspecting an inspection object on a seafloor while cruising; including 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 adjustable ocean buoy bracket for supporting sensors includes a support mechanism, a bearing mechanism, and an energy supply mechanism. The bearing mechanism is bolted to the upper surface of the support mechanism, and the energy supply mechanism is bolted inside the bearing mechanism. The buoy bracket further comprises a change mechanism. Through this change mechanism, the sensor performs a reciprocal motion for cleaning, thereby prolonging its service life.
