I think ship no have time to check it.Only sample they can send to lab. We always sent it by courrier as per Master request.and courier always ask MSDS for formalities..

Good question Piet,surely checks are made,at least I hope so. Maybe Captain Ted will elaborate.

Captain Ted, I suppose you do also check the quality of what they supply you with...

The way you described the oil bunking operation Capt.Ted, you gave us landlubbers a deep insight on bunkering.
Thanks and regards.

Yes,, and for ships it is always a challenge when bunkering at anchorages. In Gibraltar, if you get will say 1000 tons,,they stop pumping at 9-950 and claiming they pumped already 1000,, then the hackling starts,,20 more and 20 more. Last time when that happened to me in Gibraltar,, I told the bunkering ship,, well guys you needs us to let go your lines that you can go to the next ship for your next monkey business,, they did not want,,,after 4 hrs waiting they "suddenly" discovered that I was correct and they gave us the still 35 ton missing. Bunker business is the biggest crook business in shipping !!!!!

Bunkering is a very profitable business Piet, and more of these tankers are being converted for this job.

Seaway, very correct. Although nowadays modern product tankers are also heavily engaged in the palm oil trade albeit sometimes as a repositioning cargo.

Or Palm oil.

One of the typical cases where wear and tear make the ship no longer suitable (and accepted by the market) to do what she was designed for, i.e. carrying chemicals and white products. She therefore got relegated to the bunker fleet, which does not really require high tech sophisticated ships.
