Abstract

Ballast tank is an important part of ship. As sea water is highly corressive towards mild steel,rate of ballast tank
corrosion is important factor which decides ship’s safe working life. Continuosly submerged uncoated steel corrodes at
approximate rate of 0.1 to 0.2 mm/year Literature survey was carried out to analyse different methods to counter the
corrosion problem. Some of the suggested measures are (a) introducing low sulpher inert gas,(b) using improved coating
schemes ,(c) using DNV approved marine points. VOS ( Ventury Oxygen Stripping) system removes 95% of dissolved
oxygen from ballast water in 10 seconds. The low oxygen gas is created by combustion of low sulpher diesel in a device
similar to tanker inert gas generator. VOS is very effective system to protect ballast tank from corrosion.
