Question 4433 Deck General

The correct answer is A) fully ballasted. For optimal stability during jacking operations, the mat ballast tanks or spud cans should be fully ballasted. This ensures that the vessel's center of gravity is lowered, providing a stable platform for the jacking operations. Fully ballasting the tanks or cans increases the vessel's overall stability and reduces the risk of tipping or other stability-related issues during the jacking process. The other options are incorrect because: B) empty tanks/cans would reduce stability, C) sealed tanks/cans would not provide the necessary ballast, and D) partially ballasted tanks/cans would not offer the same level of stability as fully ballasted ones.
