Q

On a MODU, the keel is the primary strength member of the lower hull form in which direction?

🔍 Key Concepts

• Keel as the main strength member of a hull • Difference between longitudinal and transverse strength in ship structures • Basic hull girder bending (how a hull acts like a beam in waves)

💭 Think About

• Think about how a hull bends when it is supported by waves along its length—what direction must the main strength member run to resist that bending? • Which direction (front-to-back, side-to-side, or up-and-down) would best carry the majority of the ship’s global bending loads? • On most ship-shaped or barge-like lower hulls, how is the keel usually oriented relative to the centerline?

✅ Before You Answer

• Identify which axis is bow-to-stern and which axis is port-to-starboard • Recall that the keel lies along or near the centerline of the hull form • Confirm whether the main strength member is meant to resist bending along the length of the hull or across its width
