You are only able to submit a request in active port, for registered fuel types. If you can't find a specific port when submitting a request, it means that there are no registered bunker fuel suppliers at that port. Same goes for fuel type - if you can't find a specific fuel type in the drop down list, it means that there are no bunker fuel suppliers providing this type of bunker fuel registered on Moorio. New suppliers join Moorio network each day, so feel free to submit your request at at later time.
You can always recommend suppliers you know to join Moorio by using our Referral Program.
