According to Lagrange dynamical equation and Kriloff theory, the mathematical model of integrated anti-roll system "ship -fin stabilizer-passive anti-roll tank" is built up.
The utility model discloses a reverse osmosis vacuum degassing device comprising a water inlet tank and an integrated degassing water tank between which an energy recovery device is connected.
The integrated statistics calculate totals for distance, fuel and expense and average, maximum and minimum for consumption, distance per tank and fuel price.
