WebDec 1, 2008 · Finally, the model was used in an anti-rolling system on a ship and the reduction of roll was much better than what could be achieved by passive anti-rolling tanks. With the increasing importance of ocean exploitation, providing anti-rolling stability for ships at anchor has become more and more important. WebThe U-Tank Roll Damping system uses a passive free surface U-tube type roll damping tank. The stabilizer consists of two wing tanks interconnected via a crossover duct either through or above the double bottom and a closed air duct system including remote operated valves. Hoppe offers different types of U-Tank Roll Damping systems.

Fitted with baffles intended to slow the rate of water transfer from the port side of the tank to the starboard side and the reverse, the tanks are designed such that a larger amount of water is trapped on the higher side of the vessel. This is intended to reduce the roll period of the hull by acting in opposition to the free surface effect.
