The World: Shady shipping

 

“The peace talks between the United States and Iran have been stuck for a month. On Sunday, President Trump dismissed Iran’s most recent demands as “TOTALLY UNACCEPTABLE!” According to Iran’s state broadcaster, the country’s leaders wanted the U.S. to pay war reparations, end sanctions and — crucially — recognize Iran’s sovereignty over the Strait of Hormuz.

 

Iran’s chokehold on the strait and the U.S. blockade are a source of global economic pain. But the ships occasionally making it out — a Russian oligarch’s yacht, two German cruise ships and the odd L.N.G. tanker — have also become a source of fascination. How did they pull it off? Who is allowed out, and why?

 

For such a narrow, critical waterway, it’s striking how difficult it is to fully understand what’s happening. Today my colleague Jenny Gross, one of our business reporters, writes about how the strait is offering us a glimpse into the shady world of shipping.

 

The darker side of global shipping

 

By Jenny Gross

 

Since the war began, my main focus as a reporter has been chasing down the fates of the more than 1,500 ships that got stuck in the Persian Gulf.

 

My colleagues and I spend our days poring over databases of ship crossings and interviewing analysts, shipowners and operators — and yet we still miss a fair amount.

 

Consider one Iran-flagged tanker, the Huge. The ship surprised analysts when it turned up in Southeast Asia on May 3, having seemingly slipped through the Strait of Hormuz just before the start of the U.S. blockade. Few had tracked the more than 300-meter-long ship during its weekslong journey; the Huge had turned its location transponder off.

 

Some ships report false positions or paint fake names on their hulls. Other ships hide the origins of the oil they are carrying by transferring it from ship to ship in the middle of the sea. And others sail under the flags of different countries without those countries’ permission.

 

Some do all of the above.

 

All this to say — if we don’t have a clear picture of what’s happening in the strait, it’s not because we’re not trying. It’s because these ships don’t want to be seen.

 

The International Maritime Organization, a U.N. agency, sets out rules that govern the shipping industry, including through the Strait of Hormuz. Most companies abide by those rules. But some do not, because ships operate in international waters and across jurisdictions, making rules easier to circumvent for those looking to evade sanctions or carry illicit cargo.

 

The current murkiness in the Strait of Hormuz is revealing some of this darker side of global shipping. The sector is extremely important and can also be remarkably lawless. In parts of the sector, shady actions have become somewhat routine. It’s just that most of the time, the world isn’t paying such close attention.

 

How to disappear a tanker

 

I usually start my days by looking at a map of red, green and blue arrows on MarineTraffic, a firm that uses vessels’ transponders to track which ships have transited the strait and by what route. What I see gives me some idea of what ships are where. But it’s not a complete picture.

 

On Thursday, for example, transits through the strait appeared to drop to zero. But a satellite analysis by Windward AI found that nine heavy commercial vessels had, in fact, moved through the strait that day. They did so without switching on their location trackers, a key part of the global system that keeps tabs on vessel activity and traffic.

 

Another way vessels avoid detection is through spoofing, which involves falsifying data from the transponder that transmits the ship’s name, location, route and other identifying information. Telltale signs of spoofing include ships appearing to be in odd places. Recently, that included one ship that digitally appeared in Iran’s capital city, Tehran. Another showed up in the Saudi Arabian desert.

 

These tactics have long been deployed by ships trying to evade detection, such as those surreptitiously transporting oil in violation of sanctions.

 

But the logjam in the Strait of Hormuz — and the U.S. government’s interest in breaking it — has prompted shipping companies with no ties to Iran to shut off their transponders or use other tactics to obscure their locations. In fact, a U.S. official told my colleague Eric Schmitt last week that, during “Project Freedom,” the U.S. government itself recommended that some ships trying to exit the strait go dark for their own protection.

 

‘A huge risk problem for everybody’

 

When ships do not follow the rules, operating outside the reach of international law, it’s more than just a niche problem. These deceptive tactics enable illicit trade around the world, allowing sanctioned countries like Russia, Iran and Venezuela, as well as nonstate actors like drug cartels, to covertly ship oil, using what are known as “ghost fleets” or “shadow fleets.”

 

“The rules upon which global trade is based are not that enforceable,” said Richard Meade, the editor of Lloyd’s List, a shipping publication.

 

These practices also make the seas less safe by increasing the chances of collision — and by creating “a huge risk problem for everybody,” according to Andreas Enger, chief executive of the Norwegian shipping company Höegh Autoliners, in a recent call.

 

What the situation in the strait illustrates is how effective these tactics can be. If they can help vessels make their way, largely unseen, through a waterway just a few dozen kilometers wide — a strait that’s at the center of one of the world’s most important news stories — imagine the challenges of tracking down a ship on the open ocean that doesn’t want to be found.” [1]
