STABILISER AND ANTI-HEELING TANK SYSTEMS COMBINED
This article discusses a combined stabilizer and anti-heeling device in one tank system. This was developed to enable fast cargo handling, avoid damage to unlashed cargo at sea and improve the comfort of passengers and crew. It has now been extensively fitted on ro-ro vessels, ferries and container ships where side tanks can be provided, the space between them being available for cargo. The system is based on an athwartships U-shaped tank half-filled with water which is controlled to reduce the roll motion of the vessel at sea and the heel during loading and discharging. Side tanks contain the water and are connected by a water cross duct which is normally passed through the double bottom. Air exchange between tanks can either be through the atmosphere of the cargo holds or through another athwartships cross duct. One arrangement that has proved advantageous is to place the engine control room between the side tanks with the water cross duct running underneath. In larger ro-ro vessels the tanks can be arranged one or several decks higher with the cross ducts in the transverse beams.
