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?
Official USCG Answer & Rule Citation
Correct Answer: Option C — 10.57 feet
Back-loading bulk tank contents removes weight from the MODU. Using the capacity tables and hydrostatic curves in the COASTAL DRILLER Operating Manual, subtracting this discharged weight decreases displacement, resulting in a new operational draft of 10.57 feet.
