  • Tanker hull modification
    Patent number: 3938457
    Abstract: In a large ocean going oil tanker vessel having water ballast compartments that cannot be utilized for oil cargo also the amount of ballast water required to submerge the vessel to a predetermined ballast draft is reduced by cutting away a portion of the midbody of the hull starting at and extending below the predetermined ballast draft waterline on the sideshell, thereby reducing the amount of buoyancy in the hull that the ballast weight must overcome to sink the vessel down to the ballast draft.
