Abstract: 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.

Abstract: An improved flowable fill material and method for producing same that provides a medium for disposal of waste wood or other reclaimed debris, including wood treated with anti-microbial and/or anti-fungal materials including those containing copper, chromium and arsenic bearing compounds. The flowable fill material, comprised entirely of recovered and/or recycled materials, provides a medium for the safe disposal of chipped wood or other recovered waste by effectively encapsulating wood chips and substantially retarding further decomposition. Encapsulation of treated wood substantially reduces leaching of arsenic and/or other toxic substances contained therein. The systematic mixing of water, Class C fly ash, and wood chips in specific proportions carries out the present invention.
