Why cleaning tanks is a trade of its own
Between incompatible cargoes, tank cleaning decides whether the next liquid is fit to load.
When the purchase is complete, return to the original window. It will refresh.
From the opening
When a tanker changes from one cargo to another, what remains on the steel can spoil the next liquid. Tank cleaning is the work of removing that residue to a standard the next shipper will accept, and it is a trade with its own crews, chemicals, and tests. The opening covers the next cargo sets the standard, crude oil washing strips residue, and wall-wash tests decide acceptance.
The rest of the brief — the later sections and the reading notes — opens after Stripe confirms payment.
