Product information
Residual fuel oils and distillates are the two main oil product types on the bunkering market. The quality depends on the refinery and the grade of crude oil processed.

Interbunker Management Ltd offers both residual and distillate fuels as per follows:

Used lubricating oils (ULO):
Calcium and Zinc; or Calcium and Phosphorusmg/kg
The fuel shall be free from ULO, and shall be considered to contain ULO when either one of the following conditions is met:
Calcium > 30 and zinc >15; or
Calcium > 30 and phosphorus > 15.

This residual marine fuel grade is formerly DMC distillate under ISO 8217:2005.

The purchasers shall ensure that this pour point is suitable for the equipment on board, especially in cold climates.

The purchaser shall define the maximum sulphur content according to the relevant statutory requirements.

Strong acids are not acceptable, even at levels not detectable by the standard test methods for SAN.
As acid numbers below the values stated in the table do not guarantee that the fuels are free from problems associated with the presence of acidic compounds, it is the responsibility of the supplier and the purchaser to agree upon an acceptable acid number.

A sulphur limit of 1.00% m/m applies in the Emission Control Areas designated by the International Maritime Organization. As there may be local variations, the purchaser shall define the maximum sulphur content according to the relevant statutory requirements, notwithstanding the limits given in this table.

Applicable if sulphur is less than 0.050% m/m.

If the sample is dyed and not transparent, water test shall be required. The water content shall not exceed.

Important: Our products always comply with ISO standarts and the upgraded specifications of the classification societies.
