Question 4327 Deck General
70% to passThe COASTAL DRILLER, when underway was loaded as shown in Sample Load Form #1 (Rig Move). It is now preloaded at minimum air gap waiting for all settling to take place. The preload, weighing 7,191.7 kips, has LM 870,196 ft-kips and TM 2,158 ft-kips. What is the bow leg reaction?
The correct answer is A) 7,026 kips. To calculate the bow leg reaction, we need to use the formula for bending moment and the given information about the preload. The bow leg reaction is the vertical force at the bow of the vessel, which can be calculated from the total moment (TM) and the longitudinal moment (LM) of the preload. The bow leg reaction is calculated as: Bow Leg Reaction = (LM / Length) + (TM / Beam) Given: LM = 870,196 ft-kips, TM = 2,158 ft-kips Plugging in the values, we get: Bow Leg Reaction = (870,196 / Length) + (2,158 / Beam) = 7,026 kips. The other answer choices are incorrect because they do not accurately reflect the calculated bow leg reaction based on the provided information.
