Abstract
The invention provides improvements to the tensioner pads (513) which engage with the surface of elongate articles in tensioners such as used on offshore pipelaying and construction vessels to deploy products such as pipelines, cables and umbilicals, wherein tensioner pad assemblies (511) according to the invention may include; two or more tensioner pads and present a first tensioner pad to the product when in a first configuration and present a second tensioner pad to the product when in a second configuration; a split tensioner pad with a means (525) for controlling the separation between the portions (513i,513ii) of the pad; and combinations thereof.
