🔍 Key Concepts

• Safe working load (SWL) and why it matters for mooring line safety • How windward and leeward mooring lines share load in a storm • Goals of mooring adjustment on a MODU (Mobile Offshore Drilling Unit) during heavy weather

💭 Think About

• In a storm, what is the main safety priority for the mooring system: equalizing every line, favoring certain lines, or protecting against overloading? • How does wind and sea direction affect which lines carry the highest load, and what must be controlled to avoid line failure? • Which option directly addresses a specific, measurable safety limit that an operator can monitor on a tension panel?

✅ Before You Answer

• Identify which choices talk about a clear safety limit versus vague or operationally impractical conditions. • Consider whether it is realistic or required that all lines have different tensions or that leeward lines should always be tighter than windward lines in a storm. • Ask: Which choice describes a condition that can be continuously monitored and used as a clear operational criterion on a MODU mooring system?
