What is the shift in KG if all the liquid mud is dumped when the DEEP DRILLER is loaded as shown in the Sample Load #3 (Preparing to Drill)?
• Longitudinal Center of Gravity (KG) and how it changes when weight is removed • Using the moment = weight × distance concept with liquids in tanks • How removing weight affects KG when the removed weight is below the original KG
• Where is the vertical position of the liquid mud relative to the vessel’s original KG in Sample Load #3? Is it above or below? • When you remove weight that is located below KG, does KG move up or down, and why? • What formula from the stability booklet do you use to calculate the change in KG when a weight is removed, and which values from the mud tanks go into that formula?
• Confirm the vertical position (KG) of the mud from the stability data for Sample Load #3 • Use the correct total displacement of the DEEP DRILLER in Sample Load #3 when applying the KG-shift formula • Double-check your units so that weights are in long tons and distances in feet before doing the final division
