UG: Jacket Installation

Availability: ,

In order for a crane with a single hook to be used for the upending operation, the jacket needs to be lowered in the horizontal position into the water then and then float of its own accord. 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.
