Question 1 of 29218

The COASTAL DRILLER is loaded as shown in the Sample Load Form Number 1 (Rig Move). If the contents of the four bulk tanks are back-loaded to a supply boat, what would be the new draft?

🔍 Key Concepts

• Displacement change and draft change – how removing weight from the vessel affects draft • How to read the Sample Load Form Number 1 (Rig Move) to find total weight and individual tank loads • Using TPI (tons per inch immersion) or draft‑displacement data to convert a weight change into a draft change

💭 Think About

• First, determine the total weight of the contents in the four bulk tanks from the load form. What is the combined weight you are removing from the rig? • After removing that weight from the original condition, what is the new total displacement of the COASTAL DRILLER? How do you get from displacement to draft on this form? • Check whether the draft change should be up or down when you remove weight, and whether your final draft makes sense compared to the original draft shown on the sample form.

✅ Before You Answer

• Verify the original draft and displacement of the COASTAL DRILLER from the sample load form before any weight is moved • Verify the exact weight in each of the four bulk tanks (don’t forget units: barrels vs tons, etc.) and be sure you’re using weight, not volume • Use the correct hydrostatic data or TPI value for the COASTAL DRILLER from the exam booklet to convert the total weight removed into a change in draft, then add/subtract that change correctly from the original draft
