Question: What should be first attempted if compliant fuel is unavailable?

• 
  To explain why the vessel does not have a scrubber fitted
  
• 
  To report that despite best efforts made, the vessel is not able to bunker compliant fuel.
  
• 
  To ask Flag for an exemption from the MARPOL Annex VI applicable sulphur limits
  
• 
  To complain for not finding compliant fuel
  

• 
  A vessel cannot bunker more HSFO (unless using a scrubber), after January 1st 2020 but she can still burn the HSFO still on board
  
• 
  The vessel should proceed to anchor and organise for it to be discharged - she cannot proceed on her passage until the fuel has been removed
  
• 
  HSFO can be used as long as it has been fully mixed with new compliant fuel in the tank
  
• 
  All remaining fuel to betransferred into a single storage tank which will be sealed and noted in ORB (No non compliant fuel can be on board in any capacity after 1st March, 2020)
  

• 
  Monthly
  
• 
  After the ship completes a voyage burning non-compliant fuel
  
• 
  Every time the ship calls a bunkering port in case the fuel to be bunkered is non-compliant
  
• 
  As soon as it becomes evident that the ship will be forced to bunker non-compliant fuel
