🔍 Key Concepts

• How the transverse metacentric height (GM) and height of the transverse metacenter (KM) are related to the ship’s center of gravity (KG) • Using the hydrostatic curves or stability booklet for the COASTAL DRILLER at a specific displacement (13,011 kips) • Recognizing that transverse metacenter height comes from the vessel’s stability data, not from a generic formula alone

💭 Think About

• At a known displacement, what specific value do you normally read directly from the hydrostatic/stability curves: KM, KG, or GM? • Once you identify whether the question is asking for KM, GM, or KG, which of these answer choices looks more reasonable for a metacenter height, based on typical ranges for offshore vessels? • How does the displacement value (13,011 kips) guide you to the correct line or point on the stability curves for the COASTAL DRILLER?

✅ Before You Answer

• Confirm whether the question is asking for KM (height of transverse metacenter above keel) or GM (metacentric height between G and M) • Verify that the value you pick is within a realistic range for a metacenter height on a large offshore vessel (not extremely small or unrealistically large) • Ensure you are matching the correct displacement (13,011 kips) to the corresponding metacentric data on the vessel’s hydrostatic or stability curves
