Low Sulphur Fuel Oil Change Over Calculator
Guidance Notes :
The compatibility between the HSFO and LSFO should be verified before commencing the change over process.
Lloyd’s Register FOBAS will be happy to assist anyone requiring further guidance.
This tool provides an estimate of the time required to dilute and flush through HSFO to meet the legislative sulphur limits required for operating in a SOx Limited Zone (SLZ), such as a SOx Emission Control Area (SECA), EU Directive 2005/33/EC or CARB. Please fill in all the data fields and select the required sulphur limit from the drop down menu or define your own value to determine time and cost involved to achieve the sulphur limit at the engine inlet. The calculation is based on a complete linear blend of the two fuels during the dilution stage. It should be noted that this calculation is an estimate for guidance purposes and that spot samples to check actual sulphur content at various stages of the dilution process are recommended to account for any operations not considered.
It is necessary to ensure that adequate quantities of ready-to-use oil fuel for engines and boilers used for propulsion and generation plant remain continuously available during any changeover procedures from HSFO to LSFO.
In addition it is necessary to confirm with engine and equipment manufacturers that main and auxiliary engines, boilers and associated fuel treatment equipment are suitable for use of low sulphur fuel oils and implement any recommendations made by the manufacturers.
This calculator applies to fuels passing through the heavy fuel oil system only. It is not applicable to disitillate fuel being supplied directly from the distillate fuel oil tank.
