Question 3389 Deck General

The correct answer is A) wind. The overturning forces acting on a floating jack-up rig are generally dominated by wind forces. Wind exerts a significant force on the rig's above-water structure, creating an overturning moment that can destabilize the rig. In contrast, tidal forces, currents, and waves, while also contributing factors, are typically less dominant in causing overturning compared to the wind's impact on the rig's superstructure. The other options (B, C, and D) are incorrect because, while they can contribute to overturning forces, they are generally less influential than the wind in this specific scenario involving a floating jack-up rig.
