Abstract
A method and apparatus for reducing fluid turbulence in a flexible pipe are disclosed. The method includes the steps of urging an elongate roll of liner material along a bore region provided by an inner surface of an innermost layer of a flexible pipe body, and at least partially unfurling the roll of liner material thereby extending the roll of liner material radially outwardly in the bore region into an abutting relationship against the inner surface of the carcass.
