You are operating a liftboat. When jacking down and a leg becomes stuck on the bottom, you should __________.

Correct Answer: Option C — jack the barge down part way to pull the leg free

Standard liftboat operating procedures dictate that when a leg becomes suction-stuck on the seabed during jacking down, the barge should be jacked down part way. This introduces downward hull weight and buoyancy forces against the stuck leg to break bottom suction safely.
