🔍 Key Concepts

• Marine riser emergency disconnect criteria on DEEP DRILLER • Relationship between ball joint angle limits and mooring line tension limits • Typical practice: using a percentage of maximum allowable mooring line tension as the disconnect trigger

💭 Think About

• First, think about why you would disconnect the riser when the ball joint angle approaches 10°. How does that same level of risk translate into a safe upper limit for mooring line tension? • Compare the answer choices to what you would expect for a "warning" or "action" limit versus an ultimate breaking strength. Which value looks more like an operational limit rather than a catastrophic failure load? • Ask yourself: would the rig want to disconnect before or at the point where mooring lines might actually fail? Which range of tensions would make sense as a conservative trigger?

✅ Before You Answer

• Check which tension value is consistent with a safe operating limit, not the line’s ultimate breaking strength. • Verify which of the listed tensions you’ve previously seen associated with DEEP DRILLER’s red (disconnect) condition in its operating or station-keeping procedures. • Be sure the value you choose lines up sensibly with the given 10° ball joint angle—both should represent a similar level of approaching, but not yet exceeding, structural limits.
