Anti-piracy technology?

April 16, 2009

You’re probably as thrilled as I am by the U.S. Navy’s dramatic rescue of an American ship captain, Richard Phillips, who was being held captive by pirates off the coast of Somalia. (That is, unless you’re a Somali pirate, in which case you’re probably vowing revenge.)

Wait! There's more! Could science and technology be used to prevent these attacks from happening in the first place? Keep reading...

But the incident also reminds us that piracy, a crime with a history that goes back to the ancient Greeks, remains a serious problem all over the world today. The International Maritime Bureau’s Piracy Reporting Centre publishes a list of piracy prone areas that includes the coastlines of nations ranging from the Philippines to Brazil.

A recently-released Rand Corporation report says there were 1,845 reported pirate attacks on ships from 2003 through 2008, and that 889 crew members were abducted in 2008 alone. Rand estimates that piracy is costing the shipping industry somewhere between $1 billion and $16 billion in losses annually.

And pirates aren’t merely brandishing cutlasses anymore. Increasingly, they’re armed with automatic rifles, rocket-propelled grenades and even anti-ship mines. And as impressed as I am with the Navy SEALs’ guile, ingenuity and fearsome marksmanship skills, it doesn’t seem as if there’s an easy military solution to the large piracy problem. With pirates ranging over vast areas, the world’s navies simply can’t protect every merchant ship on a 24-7 basis. What about providing guns to merchant crews for their defense? And here’s a New York Times article that explains why that might actually endanger ships and sailors even more.

But maybe scientists and engineers are the ones who really can defeat pirates. What if the nations of the world require all merchant ships to be equipped with an array of sophisticated nonlethal technology to thwart potential hijackers?

This approach might have some obvious pluses. If we can stop pirates without having to kill them, maybe we can keep the level of violence on the high seas from escalating still higher. And if we make it difficult enough for them, the whole piracy thing may start seeming like too much work, and its practitioners may be encouraged to give up and switch to some more lucrative and hopefully less menacing pursuit.

The downsides: Anti-piracy technology is going to cost money, though probably nowhere near as much as it cost the U.S. Navy to deploy a destroyer, an amphibious assault ship and a team of SEALs to rescue Captain Phillips. There’s also the question of whether or not it will actually work. And presuming that it gets the job done, there’s always the possibility that pirates will develop more technologically sophisticated—or even more violent—new methods to overcome such defenses.

Ingenious ship crews already have come up with a few low-tech measures for frustrating would-be hijackers. For example, when a gang of armed pirates stormed the Zhenhua 4, a Chinese merchant ship, in the Gulf of Aden last December, sailors fought them to a standoff by dousing the attackers with water hoses, setting off improvised incendiary bombs and even pelting them with beer bottles. 

Once the pirates get on board, though, it’s usually too late to prevent them from taking over. That’s why most anti-piracy inventions aim at keeping them in the water. One such device is the Secure-Ship, a system of electrified wires along the edges of ship decks that can deliver a non-lethal eight-joule shock to an intruder.

Another approach is American Technology Systems’ Long Range Acoustic Device, which projects an ear-splitting noise over a distance to drive away pirates.

GCaptain.com, a website for maritime professionals, has compiled a handy list of other nonlethal devices, some of them originally invented for military use, that might be utilized as well to protect ships.

One is Southwest Research Institute’s Mobility Denial System, which could spray a viscous gel on ship decks, causing pirates to lose their footing and land on their scurvy posteriors while the crew takes refuge behind locked hatches. Raytheon’s Silent Guardian device, could force pirates back by subjecting them to focused beam of millimeter wave energy. As Raytheon’s product brochure explains:

The beam travels at the speed of light and penetrates the skin to a depth of 1/64 of an inch, producing an intolerable heating sensation that causes targeted individuals to instinctively flee or take cover. This sensation ceases immediately when an individual moves out of the beam or the operator steers the beam away. Silent Guardian does not cause injury because of the shallow penetration depth of the millimeter wave and safety features designed within the system.


Yet another intriguing nonlethal device with potential anti-pirate applications is the U.S. Air Force’s Personnel Halting and Stimulation Response weapon. The PHaSR could project nonlethal laser beams that would “dazzle” pirates, preventing them from seeing in the direction of the device.

So what do you think? Does it make sense to equip merchant ships with such technology? Or should sailors stick to using fire hoses and throwing beer bottles? Express your opinion below.
