Robotic Boats to Battle Pirates

I found this article on the BBC News website, where they are talking about the need for patrols against pirates on the high seas.

Passengers aboard the Seabourn Spirit, a luxury liner sailing off the coast of Somalia, came face to face last month with the growing problem of piracy, especially planned assaults and ocean hijackings using fast boats and sophisticated weapons.

As the pirates go hi-tech, so ships must use more advanced technology in their defence, according to the latest report from the International Maritime Bureau.

Anti-piracy technologies endorsed by the bureau include an unmanned spy plane, the Inventus UAV, for aerial surveillance of risky waters.

Others include Secure-Ship, a 9,000 volt electric fence that when rigged around ship's deck stops the pirates from boarding, and ShipLoc, a hidden tagging device for ships that allows satellites to track ships on behalf of their owners even after a hijacking.

In their defence against pirates off the coast of Somalia, the Seabourn Spirit's crew used an acoustic weapon that focused a deafening alarm sound on the attackers, hastening their retreat.

In the future, robotics could play a role in anti-piracy defences, though the technology has yet endorsed by the International Maritime Bureau.

Pirates are coming up with more ways of seizing ships
Speaking to BBC World Service's Discovery for its programme on the future of shipping safety, Keith Henderson of Marine Robotics International explained how unmanned robotic vessels could help.

Marine Robotics have created vessels called Ghost Guard which can patrol the seas along pre-programmed routes, overseen by a single, human controller on shore.

The boats can also escort other ships through dangerous waters. Video and other equipment on board these robotic ships allow their on-shore controllers to see and interact with the crew of any vessels they encounter:

"They could go alongside, there's a loudspeaker and a microphone so they could have a conversation with the vessel," said Mr Henderson.

"And if they feel that there's something suspicious then they could call up a naval patrol vessel."
