Question

While being towed at a 19.5 foot draft, the DEEP DRILLER experiences single amplitude rolls of 10&deg; with a period of 8 seconds. You should __________.

Accepted Answer

Option A: ballast the rig to a 45 foot draft and check the vessel motions. Mobile Offshore Drilling Units (MODUs) operating under specific marine manuals must adjust draft during heavy motions. Ballasting to a 45-foot draft increases stability, lowers the center of gravity, and dampens excessive roll amplitudes to protect structural integrity during towing operations.
