Abstract
A method and an apparatus of manufacturing flexible pipe body (100) is disclosed. The method includes the step of winding at least one composite body having a substantially helical innate shape around an underlining pipe layer.
Claims29
A method of manufacturing flexible pipe body, comprising the step of:
- winding at least one composite body having a substantially helical innate shape around an underlying pipe layer.
A method of providing a helical composite body, comprising the steps of:
- providing a resin impregnated fibre by pulling at least one fibre element through a resin bath;
- and
- providing a cured composite body by curing the resin impregnated fibre in a linear die;
- whereby
- the cured composite body is provided in a helical shape by determining at least one parameter associated with the impregnated fibre in the die.

Apparatus for providing a helical composite body, comprising:
- a linear die for curing a resin impregnated fibre provided from a resin bath;
- and
- a puller unit that pulls the cured composite body from the linear die;
- wherein
- an effective location of a pulling force provided by the puller unit is offset from a straight through path associated with a die and/or the puller unit and die are selectively rotatable with respect to each other to provide a composite body having an innate helical shape.
