🔍 Key Concepts

• Construction materials commonly used for MODU (Mobile Offshore Drilling Unit) survival craft • Properties of fire-retardant materials used around high heat and flame sources • Why certain materials (like foam, wood, steel, fiberglass) are or are not ideal for lifeboat hulls

💭 Think About

• Think about which material is commonly used for modern lifeboat and rescue boat hulls on offshore installations • Consider which of the listed materials can be made structural, strong, corrosion‑resistant, and shaped easily, while also being treated to resist burning • Ask yourself which materials on the list would melt, burn, rot, or corrode too easily to be the standard construction for survival craft hulls

✅ Before You Answer

• Identify which option is the typical hull construction material for enclosed lifeboats and rescue boats on MODUs • Eliminate any material that is primarily used as flotation inside rather than as the main hull shell • Rule out materials that are not practical for molded enclosed survival craft or are easily combustible in their normal form
