Sonar systems can add a new layer of underwater threat detection to port security

Steve Campbell discusses how advanced sonar technologies can be used to protect ports, ships and divers from underwater threats from terrorists, drug smugglers and criminals

A diver swims up to a ship docked at portside and quickly detaches something from the hull. Terrorist divers swim up to a ship to sacrifice themselves as suicide bombers, blowing up the ship or, in the case of Mumbai in 2008, attack tourist hotels. These incidents highlight a hidden weak spot in perimeter security. How, therefore, are we ensuring the underwater security of our ports, ships and security personnel?

While extensive security precautions apply to air travel and important land installations, the civilian maritime industry is relatively unprotected. Ports can be entered easily underwater by vessels, especially small and medium-sized ones, and there are virtually no restrictions controlling the presence of scuba divers in a port and what they do once they’re in the water. Ports, bridges, ships and piers are often wide open for access by criminal or terrorist
