Data: Fewer than 20 cargo ships passed through the Strait of Hormuz over the weekend.

Preliminary data from the ship-tracking firm Kpler, released today at 02:28 GMT, indicated that four vessels passed through the Strait of Hormuz yesterday, Sunday, following the passage of 13 vessels on Saturday. These figures are subject to change, as some vessels disable their transponders while transiting.

The data shows this compares to 16 vessels that traversed the Strait on Friday; notably, two empty supertankers entered the Gulf with their tracking systems switched off—one bound for Iraq and the other for Bahrain. Additionally, a supertanker carrying two million barrels of Emirati crude oil departed the Strait on Thursday.

Total traffic volume remained low during the week ending August 21, as vessels cancelled transit plans or altered their routes through the northern part of the strait following attacks, according to a report by the United Kingdom Maritime Trade Operations (UKMTO).

The report added: "Traffic volume remains well below normal levels; transits detected by the Automatic Identification System (AIS) are approximately 90 percent lower than pre-conflict levels and have been declining since the peak recorded between June 24 and 26."

The authority stated that oil tanker traffic—accounting for 45 percent of the total—continued to dominate the flow of vessels through the strait. Of these vessels, tankers carrying crude oil, petroleum products, or chemicals made up 56 percent, while liquefied petroleum gas (LPG) tankers accounted for 24 percent.

Data from Kpler showed that a total of 24 cargo vessels sailed through the Bab al-Mandab Strait yesterday, Sunday, down from 32 vessels on Saturday—a figure that had marked an increase from the 22 vessels recorded on Friday. The data further indicated that two supertankers entered the Red Sea on Saturday: one carrying Iraqi Basra crude and the other sailing empty.
