Lloyd’s Register Fuel Oil Bunkering Analysis and Advisory Service (FOBAS) on Saturday (15 June) released a bulletin to highlight the publication of a biofuel guidance document by CIMAC WG7 (Fuels) following the recently published ISO 8217:2024 marine fuel standard:
Further to our last bulletin, please note that CIMAC WG7 (Fuels) in support of adopting recently published ISO 8217:2024 marine fuel standard, has released a biofuel guidance document titled ‘Marine fuels containing FAME; A guideline for shipowners and operators’ and an FAQ document on ISO 8217:2024 standard.
The focus of biofuel CIMAC guideline is onboard operations when using blends of FAME (Fatty Acid Methyl Ester) up to B100 i.e., 100% FAME allowed as per ISO 8217:2024. The document has been divided into various sections with detailed commentary on topics such as sustainability, production/specifications of FAME, onboard operational considerations, quality assessment methods outlined in ISO 8217:2024, and finally a short discussion on unestablished and/or recycled biofuels.
The FAQ document on ISO 8217:2024 helps to addresses important questions and changes made compared to the previous versions such as increasing the number of tables from two to four, inclusion of FAME based biofuels and certain test methods etc.
Please note that CIMAC is expected to release a few more documents in coming weeks to support ISO 8217:2024 standard which include ‘Overview and interpretation of total sediment test results in the context of ISO 8217:2024’, ‘Design and operation of fuel cleaning systems for diesel engines’ and ‘The interpretation of marine fuel analysis test results’.
We intend to issue another bulletin to announce the release of these documents.
