From the collection of Capt. Per Jespersen
Shore Control
As a supertanker loads one mile offshore at berth No. 1, the raised
position of indicator No. I on the large hydraulic valves (left)
indicates that the appropriate valve is open. These hydraulic valves
can be closed by line pressure during loss of power or other
emergency. The smaller, electrically operated valves (right) are used
to control the loading rate and can be operated manually in case of
necessity.
