Tankerman · Loading — Initial Rate
When loading a static accumulator product into an empty tank, the initial flow rate should be kept low until:
- AThe tank is completely full
- BThe vapor line is closed
- CThe inert gas is shut off
- DThe fill pipe outlet is submerged and turbulence/splashing is reduced✓ Correct
Explanation
A reduced initial rate (commonly about 1 m/s linear velocity) limits static generation and splashing until the inlet is submerged, after which the rate may be increased. This controls both static and vapor.
Authority: ISGOTT (initial loading rate / splash filling); 33 CFR 156
