On a cargo tank in normal use, the MAWP (Maximum Allowable Working Pressure) sets the pressure limit for which part of the tank?
Correct answer: The top.
Answer options
- AThe top Correct
- BThe middle
- CThe bottom
Why
MAWP is defined as the most pressure permitted at the highest point of a cargo tank sitting in its normal operating position. Running a tank above that rating risks leaks or even a rupture.
Tip Use the top as the reference point, because the weight of the liquid itself adds extra pressure lower in the tank.
