On a MODU, the keel is the primary strength member of the lower hull form in which direction?
AI Explanation
The correct answer is B) longitudinal.
On a MODU (Mobile Offshore Drilling Unit), the keel is the primary strength member of the lower hull form in the longitudinal direction. This is because the keel runs the length of the vessel, providing crucial structural support along the ship's long axis. The longitudinal orientation of the keel allows it to resist bending and twisting forces that the MODU experiences during operation.
The other answer choices are incorrect because the keel is not the primary strength member in the transverse (A), diagonal (C), or vertical (D) directions on a MODU. The hull structure, framing, and other components provide the primary strength in those orientations.
