The DEEP DRILLER is loaded as shown in the Sample Load Form #1 (Transit). If weather conditions make it necessary to ballast down to survival, how much ballast would be required?

Correct Answer: Option B — 4,086.5 long tons

Transitioning a semi-submersible drilling unit to survival draft requires controlled ballasting to lower the center of gravity and reduce wave action impact. Calculations from Sample Load Form #1 indicate precisely 4,086.5 long tons of ballast water are required to achieve the designated survival draft condition.
