Crime on the high seas: The world's most pirated waters · CNBC

SINGAPORE - The Ai Maru steamed alone under night skies on June 14 when a speedboat slipped in from the darkness and overtook the tanker about 30 miles off the coast of Malaysia. At 9:15 p.m., seven men with handguns and knives clambered up over the side, smashed through doors, tied up crew members at gunpoint and bashed the Ai Maru's communications equipment.

The attackers stripped the 13 crew members of their personal belongings, locked them in a room and spent the next seven hours getting to the real work at hand: stealing the cargo. A second tanker, this one piloted by more pirates, pulled alongside. The maritime robbers siphoned a total of 620 metric tons of marine gas oil from Ai Maru to their own ship.


At 5 a.m., when naval and coast guard vessels arrived at the Ai Maru, dead in the water with its lights glowing, the pirates were long gone. Their total haul, at black market fuel prices, came in at about $550,000.

Welcome to the world's most dangerous waters, where a whole new style of piracy is rewriting the playbook of maritime crime. The attack on the Ai Maru, which was documented by ReCAAP, a multinational body that combats piracy, and the International Chamber of Commerce's International Maritime Bureau (IMB), is a textbook example of the piracy plaguing the seas of the Singapore Strait and Strait of Malacca-the world's busiest commercial waterway.

Unlike the Somali pirates-who, incidentally, are now almost out of business-the pirates of southern Asia rarely, if ever, seize hostages. They're in the business of stealing cargoes of liquid fuel. And they're often not small-time, ad hoc gangs from coastal villages like the Somali crews. Instead, experts say, they're highly organized criminal enterprises that gather intelligence, coordinate attacks, work in discrete teams, sometimes have their own tankers and then sell what they steal to big, pre-arranged buyers.

"The the Horn of Africa is slowing down because the cop is on the beat there," said Richard Phillips, the subject of the Oscar-nominated film "Captain Phillips" and the real-life ex-captain of the Maersk Alabama, which was taken by Somalian pirates in 2009. "But Indonesia is a target-rich environment, with lots of vessels. And there's definitely cooperation from onshore that helps these pirates who are out there."

From a business standpoint, the boom in south Asian piracy makes a lot of sense. A third of the world's shipping moves through the Strait of Malacca and Singapore Strait each year, including most trade between Europe and China, and nearly all the crude oil that moves from the Persian Gulf to the big Asian economies like China, Japan and South Korea. About 130,000 vessels arrive in Singapore each year alone, according to both Singaporean and international estimates. That breaks down to a ship entering the strait every four minutes. And the global trade that flows through that bottleneck-only 1.7 miles wide at its narrowest point-is growing.
