🔍 Key Concepts

• MODU (Mobile Offshore Drilling Unit) construction and how accommodation/quarters modules are arranged • The difference between watertight bulkheads, structural bulkheads, and non-structural partitions • What is usually required in crew quarters: fire protection and comfort vs full hull strength or watertight integrity

💭 Think About

• Ask yourself: Do the bulkheads in the living quarters normally carry major hull loads, or are they mostly room dividers? • Consider whether crew quarters are typically part of the main watertight subdivision of the unit, or above/beyond those critical boundaries. • Think about the word "generally" in the question: which option best matches what is most common in practice for accommodation spaces, not special cases?

✅ Before You Answer

• Verify which types of bulkheads are essential for hull strength and overall structural integrity. • Check whether normal cabin/room walls in accommodation areas are usually required to be watertight like boundaries of tanks or below-waterline spaces. • Confirm that you understand the difference between a bulkhead that is part of the primary structure of the unit and one that mainly divides interior spaces.
