🔍 Key Concepts

• Load paths and stress distribution in a MODU (Mobile Offshore Drilling Unit) hull • Differences between shell (hull) plating and internal structural members like bulkheads, floors, and girders • Typical design priorities: strength, corrosion protection, and steel grade selection for outer vs. inner structure

💭 Think About

• Think about which parts of the structure directly take wave impact, slamming loads, and external pressure, and which parts mainly support internal loads. • Consider whether designers usually make the outside skin heavier or lighter than the internal framing and plating for overall strength and weight efficiency. • Ask yourself: what is normally added to deal with corrosion on the outside hull, and does that usually require changing the steel itself or adding coatings/protection?

✅ Before You Answer

• Identify which surfaces face direct seawater exposure and wave impact versus those more protected inside. • Decide which is more likely to have greater thickness for global hull strength: the outer shell or internal plating. • Verify whether corrosion resistance in practice is more often from coatings/cathodic protection or from using a different steel grade.
