What is meaning of Sloshing Effect ?

‘Sloshing’ is the movement of liquid within a hold when the vessel is rolling or pitching.

It can give rise to:
  • Structural damage caused by the slamming effect of the liquid against the ship’s side or bulkheads.
  • An electrostatically charged mist in the ullage space in holds partially filled with a mixture of oil and water, such as dirty ballast or retained tank washings. This can even occur with only a slight rolling motion.
Note :

In order to eliminate these problems, slack holds should be avoided wherever possible. This may be difficult when loaded with an oil cargo, but may be more readily achieved when the vessel is in ballast.
