A method of making a flexible pipe layer, which method comprises: commingling polymer filaments and carbon fibre filaments to form an intimate mixture, forming yarns of the commingled filaments, forming the yarns into a tape, and applying the tape to a pipe body to form a flexible pipe layer.

Thermoplastic composite

A composite for use in a flexible pipe body, said composite comprising: a first polymer layer, a second polymer layer that is bonded to the first polymer layer, and filler particles that extend from the first polymer layer into the second polymer layer, whereby the particles are partially embedded in both the first and second polymer layers.

Composite

A method and apparatus are disclosed for at least partially repairing a defect in a tubular composite layer. The apparatus comprises a plurality of independently movable abutment elements () each supported in a spaced apart relationship via a respective one of at least one support member (). Each abutment element is associated with a respective drive axis along which the abutment elements are movable and the drive axes of all abutment elements extend outwardly from a common centre point.

Layer repair

A method and apparatus for manufacturing a composite layer of a flexible pipe are disclosed. The apparatus comprises a layer inspection station comprising at least one sensor, located down stream of and in an in-line configuration with an extrusion station or pultrusion station or winding station or deposition station for providing a tubular composite layer over an underlying substantially cylindrical surface via a continuous process. The inspection station automatically and continuously determines if at least one parameter of the tubular composite layer satisfies a respective predetermined condition in at least one region of the tubular composite layer as the tubular composite layer is transported proximate to the inspection station and indicates in real time at least one of a type, size and/or location of a defect in the tubular composite layer.

Apparatus and method for manufacturing flexible pipe

A flexible pipe body and method of producing a flexible pipe body are disclosed. The method includes providing one or more composite filament () as a filament bundle (); applying a braid element () around the filament bundle as a braided bundle (); helically wrapping the braided bundle () around a flexible pipe layer (); and then curing () the one or more composite filament ().

Flexible pipe body and method of manufacture

A flexible pipe body and method of producing a flexible pipe body are disclosed. The method includes providing two or more non-bonded composite filaments () as a non-bonded filament bundle (); applying a braid element () around the filament bundle () to thereby form a braided bundle () comprising non-bonded filaments (); and helically wrapping the braided bundle () around a flexible pipe body layer ().
