Marine fuel is classified into two main categories:
- Heavy fuel – fuel oil with a viscosity of 30 to 700 mm / s (Residual or Intermediate Fuel Oil (IFO));
- Light fuel – distillates (Distillate or Marine Diesel Oil (MDO) and Marine Gas Oil (MGO)).
Currently, the shipping industry applies a single international standard – ISO 8217, which determines the qualitative composition of marine fuels. All products produced by Rosneft Oil Company strictly comply with the requirements of this standard.
International and regional environmental organisations have a significant impact on the bunker market. The International Maritime Organisation (IMO) plays the leading role in this process. The most important among the IMO measures to combat pollution is the International Convention for the Prevention of Pollution from Ships, 1973, as revised in 1978 (MARPOL 73/78).
At the moment, the most important of these standards for the world bunker industry is Appendix VI MARPOL 73/78 pertaining to the control of emissions of combustion products to the atmosphere. It defines the marine basins and SECA (SOx Emission Control Areas), where the emission of sulphur oxides is strictly controlled and restrictions are set on its content in marine fuel- no more than 0.1%. All vessels passing SECA zones are obliged to only burn such fuel in these zones, in which the sulphur content does not exceed 0.1%. The change in the sulphur content rate in fuel affects all types of fuel oil and distillates.
In accordance with the requirements of Annex VI of MARPOL 73/78, RN Bunker and Rosneft Marine ensure compliance with the following requirements for navigation in certain sea areas.
Rosneft uses its own standards in the production of marine fuels, which are fully compliant with national and international requirements.
