The reason for this is generally to add stability to a structure during rotation and/or towing – to ensure equilibrium, control and correct attitude throughout the process. This principle has been applied to structures such as dock gates as well as offshore platforms. When supplied with drawings and weight calculations by the client, we are able to work with them to determine the optimum amount of ballast required, how best to position it, and how best to secure it.

Additional buoyancy is usually also fitted as a contingency to be sure that the jacket still floats even if some of the caps fail to cause the members to flood and bringing with it the risk of the jacket becoming unstable and/or sinking unless a backup is in place.
