FRICTION RESISTANCE REDUCING SHIP, AND FRICTION RESISTANCE REDUCING METHOD FOR HULL

摘要

PROBLEM TO BE SOLVED: To provide a friction resistance reducing ship and a friction resistance reducing method for a hull, capable of effectively saving an energy consumption during navigating, by conducting friction resistance reduction with a small energy consumption. SOLUTION: A negative pressure area 41 becoming low pressure to a gas space with the navigation of the hull 10 is formed in the water. Gas is led from the gas space to the underwater negative pressure are 41, thereby releasing bubbles 42 in the water. A specified device supplies the gas toward the negative pressure area 41.
