Systems, apparatus, and methods for inspecting submerged surfaces
Embodiments of the present invention include systems, apparatuses, and methods that include a pipeline inspection apparatus containing a carriage, a first member including at least a first and second sensor configured to take a first round of measurements of a pipe, a second member including at least a third and fourth sensor configured to take a first round of measurements of the pipe, and a multiplexer. The first and second members are attached to opposite side members of the carriage. The carriage, first member, and second member are configured to surround a section of the pipe and are movably mountable on the pipe. The multiplexer receives a signal from the at least first, second, third, and fourth sensors and creates a measurement signal.
