Laden via the Cape of Good Hope, Strait of Hormuz and Strait of Gibraltar; ballast via the Strait of Hormuz, Bab-el-Mandeb and Suez Canal.
A laden VLCC draws about 22.5 m, deeper than the Suez Canal's 20.1 m limit, so the laden leg takes a longer route: via the Cape of Good Hope (avoiding Suez and the Red Sea).
Emissions and EU ETS
The round voyage burns about 2,787 tonnes of VLSFO, emitting about 8,783 tonnes of CO2. One end of the voyage is in the EU ETS area, so half of the emissions at sea count, plus emissions at the EU berth: about 4,391 tonnes of CO2, or the same number of EU allowances.
From 2026 shipping companies surrender allowances for 100% of in-scope emissions. Who pays is for the charter party to say.
