Question 1 of 29218

The COASTAL DRILLER is loaded as shown in the Sample Load Form #1 (Rig Move). What is the margin on the maximum allowable KG if winds remain less than 70 knots?

🔍 Key Concepts

• Maximum allowable KG from the Rig Move stability booklet or sample form • Difference between actual KG and allowable KG for the given wind condition • How wind speed (e.g., less than 70 knots) affects the allowable KG curve or table

💭 Think About

• Look at Sample Load Form #1 and identify the actual operating KG for the COASTAL DRILLER in that specific loading condition. Then find the maximum allowable KG for winds less than 70 knots from the appropriate table or curve. • Think about how to calculate a "margin" in stability problems: Is it based on subtraction (allowable minus actual) or some other relationship? • Consider which of the answer choices are realistic for a KG margin on a jack-up or drilling unit in a rig-move condition.

✅ Before You Answer

• Confirm the actual KG value from Sample Load Form #1 (Rig Move) and write it down clearly. • Find and confirm the maximum allowable KG for < 70-knot winds from the correct column/curve in the stability data, matching the SAME draft/leg condition. • Before choosing an answer, compute allowable KG − actual KG and compare that difference numerically to the options provided.
