The Common Rail

As I see most of active users work around the Canada. I'm working in imo type 2 chemical tanker due to nature of my vessel type. We stop by ARA ports a lot. Therefore we carry out most of bunkering operations within these ports. Their fuel quality is fine however they cut around %10 of fuel at the beginning especially almost every MGO bunkering operations. Then we start negotiation with bunker to get missing fuel back as much as we can. I hate it every time as 3rd engineer, i embark barge and before the starting operation to take notes about their tank levels ( they allow only check digital leveldatics). Is there anybody deal with same problem at ARA ports.

They're crooks, and it's part of the cost of doing business with them.
They hold the cards.
You can either get serious and win once, and they wont serve you again.
Or you can bite the bullet and get the FO you need.
I'm sure the company managers realize what's going on, I dont think as a 3rd you need to get upset over it...there's no real winning.
