Where is the keel generally located on a MODU?

Question 1 of 27070

Where is the keel generally located on a MODU?

🔍 Key Concepts

• MODU (Mobile Offshore Drilling Unit) hull arrangement and support structure • Definition and purpose of a keel on any vessel or unit • How centerline / longitudinal axes are described on ships and offshore units

💭 Think About

• Think about what the keel does structurally and how it supports the rest of the hull or hulls. • Consider how many hulls or columns a MODU might have and where a main longitudinal structural member would logically be placed. • Ask yourself: on a conventional ship, where is the keel located, and how would that idea translate to a MODU’s lower hull or pontoons?

✅ Before You Answer

• Verify which option refers to a longitudinal centerline rather than roll or rotation axes. • Check which answer best matches the idea of the main structural backbone of the lower hull(s). • Eliminate options that describe motion axes (like roll or rotation) instead of physical structural members.
