A supertanker berths at Saudi Aramco’s Ras Tanura Sea Island Terminal, part of the Port of Ras Tanura, the world’s largest crude oil export terminal complex (file). The combined carrying capacity of oil tankers calling at Saudi Arabia’s Ras Tanura fell 3% in the week ended September 21, vessel-tracking data compiled by Bloomberg show. The implied capacity of vessels calling at the complex declined to the equivalent of 9.32mn bpd from 9.61mn barrels for the prior week, according to signals gathered by IHS Maritime, a Coulsdon, England-based research company. The data may be incomplete because not all transmissions are captured. The Ras Tanura complex, including Ras al-Ju’aymah, is the biggest global crude terminal, according to the website of Aramco.
