  • Tanker ballast
    Patent number: 4759307
    Abstract: In order to reduce the economic impact of segregated ballast requirements for tanker vessels, heavy ballast, for example concrete, is placed in the segregated ballast tanks in amount to occupy 30 to 50% of the free volume of the tank. The rest of the tank may be filled with water ballast. The use of heavy ballast provides a total ballast weight equal to that obtainable with a greater number of tanks filled with water ballast only, thus increasing the available cargo space.
