FOBAS tested several samples that were all high sulphur residual bunker fuels and TSP results ranged from 0.16% m/m to 0.44% m/m.
Lloyd’s Register Fuel Oil Bunkering Analysis and Advisory Service (FOBAS) on Monday (20 October) released a bulletin regarding its testing of several samples of high sulphur residual fuels from Civitavecchia, Italy:
In recent days, FOBAS has tested several samples from Civitavecchia with Total Sediment Potential (TSP) results exceeding the ISO8217 specification limit of 0.10% m/m. The samples were all high sulphur residual fuels and TSP results ranged from 0.16% m/m to 0.44% m/m.
Further analysis on these fuels suggests a possible mix of both asphaltenes and some extraneous dirt. All samples were from the same barge and supplier so this may be an isolated incident but important to be aware.
Fuels with high sediments can result in excessive sludge deposition in tanks and throughout the handling and /fuel injection systems.
In view of the above, if your ships are planning to bunker in this port, we recommend that suppliers are advised of your concerns regarding the stability of the fuel in the area, and that they provide you with additional reassurance that they will adhere to the ISO 8217 requirements for the grade ordered. Ideally including providing full TSA, TSE and TSP sediment test results.
Additional attention should be given to the collection of bunker samples. It should be ensured that all parties have witnessed the sampling process and have signed witness forms accordingly, and that the supporting documentation includes records of all the samples considered representative of the fuel as loaded.
In April, FOBAS also released a bulletin regarding its testing of several samples of high sulphur residual fuels from Civitavecchia with Total Sediment Potential (TSP) results exceeding the ISO8217 specification limit of 0.10% m/m.
The samples were all high sulphur residual fuels and TSP results ranged from 0.83% m/m to 1.05% m/m.
