Acoustic Systems from Our Canadian Friends

TRAPS containerized active/passive towed array from GeoSpectrum Technologies.

We talked about the possibility of using TRAPS earlier. I had an email discussion with a GeoSpectrum Technologies representative, Geoff Lebans. He tells me the Canadian Navy will test TRAPS from a Kingston class ship in March. 

The Kingston class are a little smaller and slower than the 210 foot WMECs, but they have regularly assisted the Coast Guard in drug interdiction.

Would love to see how effective this system might be in detecting semi-submersibles.

The Coast Guard has expressed an interest in having unmanned systems providing networked sensors and GeoSpectrum makes a much smaller towed acoustic directional sensor that they believe would work with the Liquid Robotics™ Wave Glider™ and other small autonomous vehicles. Frankly, I could see the drug cartels putting a bounty on recovery of unmanned surface vessels and their sensors. Still the Navy might also be interested in this sort of network for ASW and they could probably fund the program out of loose change they might find in the sofa. Forth Fleet would probably more than happy to test it in the Eastern Pacific and cutters could probably deploy them.

Hopefully the Canadians will send their TARPS equipped ship down to the Eastern Pacific transit zones. If they do not, it might make a good Coast Guard R&D project to mount one on the back of a WMEC and use it to help define competitive contract requirements.

An acoustic system like this should be good for detection of something like a semi-submersible out to at least the first convergence zone, well beyond the visual and radar horizon. Mounted in a container they could be placed on WMECs bound for the Eastern Pacific and then transferred to the OPCs as they replace the MECs.
