Question 1 of 27070

If the DEEP DRILLER is damaged, the unit is designed to avoid downflooding in wind speeds up to __________.

🔍 Key Concepts

• Downflooding on a Mobile Offshore Drilling Unit (MODU) and what it means for watertight integrity • Design survival / damage conditions and the associated design environmental wind speed • Typical design wind speeds used in MODU stability manuals and the MODU Code for damaged conditions

💭 Think About

• Think about whether the design wind speed for avoiding downflooding in a damaged condition is usually a moderate operating wind or a more severe survival wind. • Compare the choices to what you would expect for a harsh-environment offshore unit that must remain safe long enough for emergency response and evacuation. • Ask yourself which wind speed is most consistent with a ‘damage stability’ or ‘survival’ limit, not just normal operating limits.

✅ Before You Answer

• Check what wind speed is normally associated with damaged stability / survival conditions in MODU or DEEP DRILLER documentation, rather than normal working conditions. • Verify whether lower wind speeds (around 50 knots) are typically used for operating limits, and higher values for survival limits. • Confirm which option best matches a design environmental wind that would be considered a severe storm scenario for an offshore unit.
