In the last two weeks Intertek Lintec tested a number of samples of VLSFO bunkers from vessels that took fuel in Rotterdam, Antwerp and Ghent which showed sediment contents above the ISO 8217 0.10% mass limit. The data collected showed results ranging from 0.27 to 0.75% mass.
The sediment tests contained in the ISO 8217 standard aim to define the total quantity of all the sediments contained in a fuel. The main reason for this is to limit the amount of solid matter contained in the fuel so that it can be removed by efficient purification and to limit clogging and blockage of filters.
Sediment testing also gives good insight into the potential stability of the fuel.
Fuels rich in sediment can interfere with the purification process and promote sludge build-up in purifiers. Reducing the efficiency of the purification can impact the removal of other components such as water and / or cat fines, which can also lead to potential wear damage.
If your vessel has recently refueled in the ARA region, we strongly recommend that you know the quality of the fuel before using it.
Ensure that samples are taken correctly with the supplier at the point of transfer of ownership (barge collector / receiving vessel collector) and in the presence of the ship’s crew. The seal numbers of the samples taken on the basis of the supply contract must be entered on the Bunker Delivery Note (BDN).
