Title
(EN) Device for and method of tensioning chains, in particular mooring legs
Abstract
(EN)

A device for tensioning anchor chains, in particular mooring legs of off-shore vessels and installations, comprises a frame carrying connectors for holding together lower and upper portions of the chain to be tensioned. The frame further carries a tensioning mechanism for pulling at least one portion of the chain towards the other portion of the chain while the device is submerged.
