| Video Discription | When the ship tilts on any of its sides i.e. port or starboard and doesn’t return back to its upright position, it is known as heeling of the vessel. Heeling is unsafe for ship, its machinery and people onboard. The main reasons of ship’s heeling are strong winds, hard and speedy turns and uneven cargo loading. Out of the three reasons, the most common cause is uneven cargo loading and unloading. Anti-heeling System The anti heeling system of a ship automatically detects the heeling angle of the ship and compensates the same. This allows the vessels to have continues loading and unloading cargo operation without stopping in between for list correction. This saves considerable amount time on the port. In this system, ballast tanks are internally connected to each other by means of pipe lines, automatic valves and control systems. When the ship heels to any of the sides, the heeling sensor sends the signal for change of ships angle with respect to the ship’s upright position to the master control panel. This change in heeling angle is compensated by methods of auto transferring the water from the heeled side to the other side of the ship, making the vessel upright. Level control switches are also installed in the ballast tank involved with the anti-heeling system to avoid low level or over filling and hence over pressurizing of the tanks. Types of Anti Heeling System There are two widely used anti heeling system on board ships: 1) Pneumatic system: This system comprises of air purging arrangement and regulating valve system to force the air on the top of ballast tank. The air is forced on one tank and purged from the other, making the water rapidly flow from pressurized to purged tank. This transfer of water is used to upright the vessel in quick time. 2) Water pump system: The pump system consists of electrical motor driven water pump, which can be a reversible or non reversible pump, connected with remote controlled valves that can direct ballast water flow in between the tanks. Advantages of Anti Heeling System: • Allows safer and rapid cargo loading and unloading. • Shortens harbour time and saves port dues. • Reduces damage to ramp, rolling cargo and containers. • Ensures safety of the ship and personals.
