🔍 Key Concepts

• Meaning of a MODU (Mobile Offshore Drilling Unit) and what documents are normally kept aboard for design and construction reference • Difference between operating/usage manuals and design/construction records • Which document set is typically created and retained by the shipyard/builder vs. what is filed by the Coast Guard

💭 Think About

• Ask yourself: which option sounds like the primary home for detailed construction records, drawings, and specifications, rather than just how to operate the unit? • Consider which documents are normally produced and controlled by the builder versus which are primarily regulatory or onboard reference documents. • Think about what kind of file the Coast Guard would maintain—would it physically contain a portfolio, or would it reference other documents?

✅ Before You Answer

• Identify which choice clearly relates to design and construction records created during building. • Separate documents intended for day‑to‑day operation from those for original construction history. • Check which option’s wording most naturally matches where a portfolio of construction information would logically be grouped.
