Japan Analyzing Damage to Tanker in Hormuz Strait

August 19, 2010

Checks on a Japanese oil tanker, damaged by a mystery explosion near the Strait of Hormuz oil shipping route, found a soot-like substance in a large dent in its hull, the Transport Ministry in Tokyo said on Wednesday.

It was unclear yet what caused the blackish substance, which was spread in a radial pattern, and it would be analyzed further, a ministry official told reporters.

Checks of the tanker’s radar showed six ships around it just before it suffered the damage, but no evidence had been found to link the incident to those ships, the ministry said.

Public broadcaster NHK said on Tuesday the tanker’s radar detected a small ship that made suspicious movements near it at the time of the incident, and that the Transport Ministry believed there was a possibility that ship launched an attack.

“More than 80 percent of oil tankers coming to Japan go through that area. An incident like this in such a region is a grave concern for us,” Transport Minister Seiji Maehara told the opening session on Wednesday of a committee set up to investigate the cause of the damage.

The incident, shortly after midnight on July 28, injured one seaman but caused no oil spill or disruption to shipping in the strategic waterway, which is the gateway to the oil-producing Gulf and handles 40 percent of the world’s seaborne oil.

A militant group called Abdullah Azzam Brigades, which is linked to al Qaeda, said that a suicide bomber belonging to it had attacked the tanker.

Some security analysts were skeptical of the group’s claim, though the United Arab Emirates state news agency said investigators had found traces of explosives on the tanker.

A senior official with the Marshall Islands, where the M.Star is registered, said it had issued an advisory urging ships to adopt heightened vigilance when transiting the Strait of Hormuz.

“We cannot positively confirm that it was a terrorist attack at this time, but the indications would imply that that might be what took place,” Thomas Heinan, Deputy Commissioner of Maritime Affairs with the Republic of the Marshall Islands, told Reuters. “And as a result we needed to advise ship owners and operators what to watch out for and what to do if a ship finds itself in a similar situation.”

Industry sources said the tanker was carrying more than 2 million barrels of Qatar Land and Abu Dhabi Lower Zakum crudes, equivalent to about half of Japan’s daily oil needs.

The dent in its hull was 22 meters (72 ft) high, of which 16 meters was below the waterline, the ministry said. It was up to 23 meters wide and caved in the hull to a depth of 1 meter.

The 333-metre-long very large crude carrier, named M.Star and operated by Mitsui O.S.K. Lines, was able to resume its voyage to Japan after checks at a nearby port.

“Even when a ship is stationary, some engines are often running to supply electricity to the ship, and smoke comes out of its chimney,” Hiroaki Sakashita, director of the Transport Ministry’s safety and environment policy division, told reporters.

“That could be what it is,” he said, referring to the soot-like substance collected from the dent.
