BALLAST

OPTIMUM SHIP

STABILITY FOR

COST SAVINGS

AND IMPROVED

SAFETY

BALLAST,* the Artificial Intelligence System designed to meet the Operational and Damage Control needs of military, commercial, and off-shore drilling vessels. BALLAST reduces stability computation time from hours to minutes.

Advantages: • Lower fuel consumption due to optimum trim. • Increased asset survivability - results in lower insurance loss ratios and premiums. • Improved crew safety.

BALLAST is a computer-based shipboard system which is effective for both routine operations and emergency conditions.

BALLAST optimizes stability during loading and off-loading... assesses post-accident or attack damage... recommends corrective action to counter instability.

BALLAST is for the captain who knows his ship inside and out, but wants the added technical edge of maintaining an optimally stable environment.
