Abstract
The invention relates to an unbonded flexible pipe comprising an internal sheath, at least one armor layer surrounding said internal sheath and a bore defined by said internal sheath, the flexible pipe further comprising a fiber sensor arranged in said bore. By arranging the fiber in the bore of the unbounded flexible pipe, new opportunities for sensing desired properties of the unbounded flexible pipe is provided. The fiber sensor may preferably be a pressure fiber sensor. The unbonded flexible pipe may preferably be an offshore pipe, such as a riser for transportation of hydrocarbons.
