 Marine Fuel Oil ENXSA specialises in marketing, brokering, and trading fuel oil originating from Europe, Eastern Europe, Central Asia, Asia, Persian Gulf, Africa, North and South America. ENXSA fuel oils are traded our Geneva and Moscow office. The fuel oil originating from Eastern Europe in particular, Russia and Ukraine, is typically high sulphur bunker quality. The fuel oil supply originating from Russia are brought to market from the Black Sea at the seaports of Novorossiysk and Tuapse in Russia. Additionally, from the Black Seaports of Ukraine in Odessa, Feodosia and Yuzhnihy. Via the Baltic seaports, at Primorsk, in the Russian enclave, St. Petersburg, Ventspils in Latvia, Tallinn in Estonia, or Butinge in Lithuania. Other outlets we bring fuel to market are from the ports of Nahodka and Vladivostok in far east Russia. Central Asia fuel oil originating from Azerbaijan and Kazakhstan, are destined to Batumi barged across the Caspian Sea then railed through the Republic of Georgia or up the Volga River and out to the Azov sea through the Kerch Strait and out to the Black Sea. Fuel oil supplies, from Romania are lifted in Constanta in the Black Sea. Other areas we lift cargos of fuel oil is the Mediterranean sea, in Spain, Italy, and France, including U.S., Canada, Mexico, and the Caribbean. Fuel oil is classified into six classes, numbered 1 through 6, according to its boiling point, composition and purpose. The boiling point, ranging from 175 to 600 °C, and carbon chain length, 20 to 70 atoms, of the fuel increases with fuel oil number. Viscosity also increases with number, and the heaviest oil has to be heated to get it to flow. No. 1 fuel oil, No. 2 fuel oil and No. 3 fuel oil are variously referred to as distillate fuel oils, diesel fuel oils, light fuel oils, gasoil or just distillate. For example, No. 2 fuel oil, No. 2 distillate and No. 2 diesel fuel oil are almost the same thing (diesel is different in that it also has a cetane number limit which describes the ignition quality of the fuel). No. 1 is similar to kerosene and is the fraction that boils off right after gasoline. No. 2 is the diesel that trucks and some cars run on, leading to the name "road diesel". It is the same thing as heating oil. No. 3 is a distillate fuel oil and is rarely used. No. 4 fuel oil is usually a blend of distillate and residual fuel oils, such as No. 2 and 6; however, sometimes it is just a heavy distillate. No. 4 may be classified as diesel, distillate or residual fuel oil. No. 5 fuel oil and No. 6 fuel oil are called residual fuel oils (RFO) or heavy fuel oils. As far more No. 6 than No. 5 is produced, the terms heavy fuel oil and residual fuel oil are sometimes used as synonyms for No. 6. They are what remains of the crude oil after gasoline and the distillate fuel oils are extracted through distillation. No. 5 fuel oil is a mixture of No. 6 (about 75-80%) with No. 2. No. 6 may also contain a small amount of No. 2 to get it to meet specifications. Residual fuel oils are sometimes called light when they have been mixed with distillate fuel oil, while distillate fuel oils are called heavy when they have been mixed with residual fuel oil. Heavy gas oil, for example, is a distillate that contains residual fuel oil. The ready availability of very heavy grades of fuel oil is often due to the success of catalytic cracking of fuel to release more valuable fractions and leave heavy residue. Bunker fuel is technically any type of fuel oil used aboard ships. It gets its name from the containers on ships and in ports that it is stored in; in the days of steam they were coal bunkers but now they are bunker-fuel tanks. 6 Oil is the most common "bunker fuel" is often used as a synonym for No. 6. No. 5 fuel oil, also called furnace fuel oil (FFO), navy special fuel oil or just navy special.   CST 180CST 280CST 380 |
