Question 4425 Deck General

The correct answer is C) 7,144 kips. To arrive at this answer, we need to calculate the port leg reaction based on the given information about the preload. Since the vessel is preloaded at minimum air gap, the weight of the preload (7,191.7 kips) and its moments (LM 870,196 ft-kips and TM 2,158 ft-kips) can be used to determine the port leg reaction. The port leg reaction can be calculated by considering the moments acting on the vessel. Given the total moment (TM) of 2,158 ft-kips, the port leg reaction can be determined to be 7,144 kips, which is the correct answer. The other options are incorrect because they do not accurately represent the port leg reaction based on the provided information.
