Fuel oil, which is distilled from crude oil and often left as residue during the refining
process, refers to a range of the least volatile and heaviest of the commercially used fuels.

Some 10% of fuel oil produced is used to power large ships.  A further 15% is used for heating and the remainder is used by refineries as feedstock for further upgrading.

World kingdom Investments is an active trader in global fuel oil markets and ships over 3.5 million tonnes of fuel oil every month, about half of which is processed as refinery feedstock. We use storage facilities in Rotterdam, Fujairah, the Caribbean and Singapore to lift high-sulphur, sour oil from Mexico, the Middle East and the former Soviet Union, and low-sulphur, sweet oil from the United States and Europe.
