Question 1 of 27070

When clear ice is present while drilling, the vertical transverse moments of the DEEP DRILLER are increased by __________.

🔍 Key Concepts

• Vertical transverse moment and how it relates to weight and distance from a reference point • Effect of clear ice accretion on a unit’s mass distribution and stability • Using given ice weights and their vertical lever arms to compute added moments

💭 Think About

• Think about what physical quantity changes when ice builds up high above the waterline on a drilling unit. • Ask yourself: do you need to add ice weights at different vertical distances and then sum their contributions, or is there a single combined value already tabulated? • Consider whether the problem likely comes from a stability booklet/operations manual table where the increase in vertical transverse moments for specific ice conditions is listed.

✅ Before You Answer

• Check if the exam question refers to a specific stability data table for DEEP DRILLER that lists vertical transverse moments for various ice conditions. • Verify whether the question expects you to read a table value directly rather than perform a long calculation on the spot. • Confirm that the units (ft-long tons) match the table column you’re using before choosing your answer.
