Question 1 of 31048

What are the maximum vertical moments, including free surface moments, permitted on the DEEP DRILLER at survival draft if the winds are greater than 70 knots?

🔍 Key Concepts

• Stability booklet / operations manual for the DEEP DRILLER at survival draft • How vertical moments including free surface are listed for different wind speeds (below and above 70 knots) • Relationship between maximum allowable vertical moment and the unit’s intact stability criteria in survival condition

💭 Think About

• First, identify the correct loading condition (survival draft with winds > 70 knots) in the DEEP DRILLER stability or operations manual tables. • Compare the maximum permitted vertical moments for winds less than or equal to 70 knots with those for winds greater than 70 knots – which table applies here? • Check how free surface effects are included in the table – is the number you need already stated as a total including free surface, or do you need to add anything?

✅ Before You Answer

• Confirm you are using the table for survival draft (not operating or transit draft). • Verify you are reading the column/row for wind speed greater than 70 knots, not the lower wind speed condition. • Make sure the value you pick is the maximum vertical moment INCLUDING free surface moments, not a net cargo moment or a separate component.
