Abstract
Apparatusdiscloses a subsea monitoring station using solar cells to energize at least one electronic circuit incorporating at least one node having a determinable circuit value or other parameter test station providing a full time voltage readout, powered by the lightson an ROV/AUVor diver's lamp. An additional element of the apparatus is a subsea cathodic protection test stationincorporating a plurality of banks of solar cellspowering DC voltage test circuits having some form of parameter display, such as voltmeter readout, deriving voltage from ambient lightprovided by outside sources, such as an ROVor diver's lamp. The apparatus's cathodic protection test system includes four integral voltmetersof which are powered with independent solar panels. The solar panelsare powered by artificial lightdelivered by diver or submersible vehicle. The test stationincludes sensorsthat are hard wired back to the solar powered voltage readouts contained within the subsea pressure housing. The readout unitcan be incorporated into the structure being monitored, the cathodic protection anode source or can be integrated into a buoyant modulewhich floats above the sea bed.
