Question 1 of 27070

In a storm, the windward lines of a MODU's mooring system provide __________.

🔍 Key Concepts

• Mooring line forces on a floating structure in waves and wind • Difference between restoring force / righting moment and overturning or capsizing forces • Behavior of windward vs. leeward mooring lines when the unit is displaced by wind and waves

💭 Think About

• When wind and waves push the MODU off position, what do the windward mooring lines do to its motion—do they tend to bring it back toward equilibrium or push it farther away? • Think about whether the term righting moment is usually used for rotational stability (heel/trim) or for horizontal offset of a moored unit. • Which of the options refers to a property that would help keep the MODU near its intended location, rather than increase the risk of drifting or capsizing?

✅ Before You Answer

• Be clear on the meaning of restoring force (does it oppose displacement or reinforce it?). • Distinguish between force (linear, horizontal) and moment (rotational, about a point). • Consider whether KM is normally affected by tension in mooring lines, or is it a hydrostatic property of the hull alone.
