FOBAS: CIMAC publishes more documents on ISO 8217:2024 marine fuel specs

Lloyd’s Register Fuel Oil Bunkering Analysis and Advisory Service (FOBAS) on Friday (5 July) released a bulletin to highlight that CIMAC WG7 (Fuels) has released more documents to support the adoption of ISO 8217:2024 marine fuel standard:

Further to our last bulletin, please note that CIMAC WG7 (Fuels) has released a very comprehensive document titled Design and operation of fuel cleaning systems for diesel engines. 

This document has three sections, first part discusses the properties of conventional fuels, second part reviews the corresponding fuel system designs, and third part provides best practice approach to handling marine fuels onboard.

Similarly, CIMAC has also published a guidance document titled The interpretation of marine fuel analysis test results which is effectively a revision of the CIMAC WG7 guideline No. 02:2016. 

The document provides information on how to apply the ISO 4259 approach to the interpretation of the analysis test results in respect of the marine fuel characteristics given in ISO 8217 from both the recipient and the supplier perspectives. This revision includes tests added in ISO 8217:2024 and incorporates updated method precision data where relevant.

Moreover, CIMAC has published important guidance titled Overview and interpretation of total sediment test results in the context of ISO 8217:2024. 

This document provides an overview of test methodologies for assessing stability and cleanliness of residual marine fuels through the interpretation of the accelerated total sediment (TSA), potential total sediment (TSP) and existent total sediment (TSE) test results.

We hope you will find these documents useful. Please note that FOBAS experts are an integral part of CIMAC WG7 who along with other members, worked extensively to produce these guidance documents.
