Tensioner Pads for laying subsea pipelines and the like

A pad for a track-type tensioner includes an interface layer made up of a plurality of rigid elements that together define a contact face of the pad for gripping a pipeline or other elongate product supported by the tensioner in use. A substrate layer of pliant material is sandwiched between a rigid...

Beschreibung
Zusammenfassung:	A pad for a track-type tensioner includes an interface layer made up of a plurality of rigid elements that together define a contact face of the pad for gripping a pipeline or other elongate product supported by the tensioner in use. A substrate layer of pliant material is sandwiched between a rigid base plate and the interface layer. The flexibility of the substrate layer supports the elements of the interface layer for movement relative to each other and relative to the base plate to suit an outer shape profile of the product. For example, by virtue of pivoting or translational movement of the rigid elements relative to the base plate, the same pads can adapt to different products that have different diameters.
