Question 4812 Deck General
70% to passThe righting moment created by a MODU that displaces 15,000 tons with a righting arm (GZ) of 0.02 foot is _______________.
A
3,000 foot-tons
B
750 foot-tons
C
600 foot-tons
D
300 foot-tons
AI Explanation
The correct answer is D) 300 foot-tons. The righting moment of a vessel is calculated by multiplying the vessel's displacement (in tons) by the righting arm (GZ) in feet. In this case, the MODU (Mobile Offshore Drilling Unit) displaces 15,000 tons and has a righting arm (GZ) of 0.02 feet. Therefore, the righting moment is 15,000 tons x 0.02 feet = 300 foot-tons. The other options are incorrect because they do not accurately reflect the calculation of righting moment based on the given displacement and righting arm values.
