USCG Exam PracticePumps, valves, and piping systems
According to 46 CFR §56.07-10, piping system designs must account for the effects of ship motion and flexure. Which of the following lists correctly identifies the motions specifically enumerated in that section?
- A. Weight, surge, sway, roll, pitch, and heave only
- ✓ Weight, yaw, sway, roll, pitch, heave, and vibrationCorrect
- C. Yaw, surge, sway, roll, pitch, heave, and thermal expansion
- D. Weight, yaw, surge, roll, pitch, heave, and vibration
Why B is correct
46 CFR §56.07-10(c) replaces ASME B31.1 paragraph 101.5.3 and specifically enumerates weight, yaw, sway, roll, pitch, heave, and vibration. Surge and thermal expansion are not listed in that enumeration; 'surge' appears in some motion lists but is not in this regulatory text.
