Q

The DEEP DRILLER is operating at the maximum allowable KGT at 60 feet draft. What is the value of GMT?

🔍 Key Concepts

• Relationship between KGT, KMT, and GMT (GM = KM − KG)** • Meaning of maximum allowable KGT in a stability booklet or curve • Regulatory or booklet minimum required GM at that draft (often tied to max KG)

💭 Think About

• When a vessel is at its maximum allowable KGT, what does that say about the GM compared to the minimum required GM? • How do you express GMT mathematically using KMT and KGT when the vessel is at this limiting condition? • Looking at the answer choices, which values are more typical of a minimum acceptable GM for a large offshore unit at operating draft?

✅ Before You Answer

• Be clear that GMT = KMT − KGT (using transverse metacenter). • Confirm that at maximum allowable KGT, the resulting GM is at its minimum permitted value for that draft. • Compare each choice to a realistic minimum GM for a unit like DEEP DRILLER; rule out answers that are unrealistically small or excessively large.
