🔍 Key Concepts

• Manufacturer or vessel-specific limits in the Operations Manual or Well Control Manual • Difference between design/maximum rated depth and current configured depth (may be different) • How changes in equipment configuration (e.g., riser, drill pipe, mud system) can reduce or cap operational depth

💭 Think About

• Ask yourself: Is the question asking for the absolute design capability, or the limit as currently configured? • Which option looks like a "round" design rating, and which looks more like an actual configured limit taken from a specific procedures or spec sheet? • Think about typical deepwater drillship or semisubmersible depth ranges, and which of these values fits a realistic operational limit for a named unit.

✅ Before You Answer

• Re-read the phrase "as currently configured" and base your choice on that, not on possible maximum design depth. • Consider which value is most likely to appear as a specific operational limit in a manual, rather than a marketing/design figure. • Eliminate any choice that looks like it would more likely be a future upgrade or theoretical maximum rather than a presently configured limit.
