OPG developed the Wirewalker as an ocean profiler designed to traverse a column of water, using the power of ocean waves as propulsion. By using a ratcheting cam system, the Wirewalker can precisely profile while carrying data collecting instruments, with the profiling rate increasing as seas get larger. The Wirewalker has proven itself to be a functional and useful tool for scientists who wish to collect high-quality ocean profiling data. The first commercial Wirewalker vehicles are now being produced and sold by Brooke Ocean Technology, US.
