The locking device is checked to make sure it is secure. Once locked
on, the valve opens. Fuel can then be pumped from the barge into the
ship’s fuel tanks.
Even the smallest spill is immediately reported. Spilt oil on water
spreads very quickly. The sooner the oil can be contained, the easier
it will be to do the cleanup. There is no hiding even a small oil spill
in a port and it is not difficult to find who is responsible. The
offending ship will be prosecuted in court and may have to pay a very
costly fine.
