🔍 Key Concepts

• Check the COASTAL DRILLER operating manual or stability booklet limits for topside weight from ice/snow • Understand how ice accumulation affects stability and freeboard on an offshore unit • Note that exam questions about a named vessel usually come from a specific table or note in that vessel’s approved documents

💭 Think About

• Which choice best reflects a realistic operational limit that would be written into a vessel’s procedures to prevent excessive top weight from ice and snow? • Think about how even small amounts of uniform ice loading over a large area can add a lot of weight—would a higher or lower thickness be more likely to be restricted? • If you had to defend your choice to an inspector, which value would you point to as being most consistent with conservative safety margins for stability?

✅ Before You Answer

• Verify what the COASTAL DRILLER procedure/operations manual actually states for maximum ice/snow depth on decks or exposed surfaces • Confirm that the value you choose would not significantly raise the center of gravity when distributed over the unit’s area • Make sure you are thinking in terms of thickness (inches) of accumulation, not weight per square foot or total added weight
