The DEEP DRILLER is loaded as shown in the Sample Load Form #1 (Transit). Additional deck load may be placed aboard. If the maximum permissible deck load were placed in the pipe racks at a VCG of 130 feet, the KG increases __________.
• Vertical Center of Gravity (KG) change when adding weight high or low • Using the KG shift formula: new KG based on existing displacement, original KG, added weight, and its VCG • Understanding what "maximum permissible deck load" means on the Sample Load Form #1 (Transit)
• From the sample load form, identify the original displacement and original KG before adding the deck load. How will weight added at a VCG of 130 feet affect KG compared to the original KG? • Write out the moment contributed by the additional deck load (weight × VCG). How does this new moment change the total ship’s moment and thus the new KG? • After computing the new KG, compare it to the original KG. What is the difference in feet between them, and which option matches that difference?
• Be sure you are using the correct displacement and original KG from Sample Load Form #1 (Transit), not from another condition • Confirm the added weight you use is exactly the "maximum permissible deck load" stated or implied in the problem data, not the total deck weight already aboard • Double-check your math: total moment before and after adding the load, then recompute new KG = (total moment ÷ total displacement) and take the difference from the original KG.
