Q

The DEEP DRILLER is operating with KGL at the maximum allowable value (70 knots) at a 60 feet draft. What is the value of GML?

🔍 Key Concepts

• Relationship between KML, KGL, and GML (how to get GML from the other two) • Using the hydrostatic data / stability booklet for DEEP DRILLER at a specific draft • Difference between transverse GM (GMT) and longitudinal GM (GML)

💭 Think About

• At 60 feet draft, what value should you read from the DEEP DRILLER hydrostatic or stability tables to find KML? • Once you know KML and you are given the maximum allowable KGL, what is the basic stability formula that links them to GML? • Are the resulting GML values for a MODU typically very small, moderate, or quite large compared with GMT?

✅ Before You Answer

• Verify the correct table/column for KML at 60 feet draft (not KMt, not KB, etc.). • Apply the correct formula: GML = KML − KGL and keep all units in feet. • Check that the magnitude of your computed GML is reasonable for longitudinal stability (usually much larger than transverse GM).
