Regulation 18.2 of MARPOL Annex VI describes the correct procedures in case of vessel not being able to receive compliant fuel:

  • Notify your flag state and the port authority at the next port of call
  • Provide evidence of actions taken to achieve compliance
  • Fill and submit the FONAR (Fuel Oil Non-Availability Report) form

N.B. FONAR is not a “license” to use non-compliant fuel!

Key messages:

  • Know your fuel!
  • Testing according to ISO 8217:2017
  • If possible – do not use the fuel before the analysis are available
  • Temperature management – viscosity is temperature dependent
  • Keep fuel segregated – until compatibility has been verified
  • Consult your engine maker’s instructions and technical bulletins
  • Bunker tank cleaning – highly recommended before filling with VLSFO
  • Fuel treatment system – ensure system is adjusted for the actual VLSFO
