Abstract

Methods and apparatus are disclosed. The apparatus includes a substantially cylindrical mount body ( 350 ) comprising a first open mouth at a first end of the cylindrical body ( 350 ) and a further open mouth at a remaining end of the cylindrical body, a substantially cylindrical inner surface, and an outer surface that includes a plurality of spaced apart substantially parallel recessed regions that extends circumferentially around the body, wherein the cylindrical body ( 350 ) is tapered at each end and at least one securing element is located between the recessed regions.

Claims (17)

1. A method of manufacturing flexible pipe body, comprising steps of:

providing a tensile armour wire layer by helically winding a tensile armour wire over an underlying layer;

providing at least one substantially cylindrical mount body, comprising a spaced apart first and further open mouth at respective ends of the mount body and a substantially cylindrical inner surface and at least one securing element between a plurality of spaced apart recessed regions in an outer surface, over the tensile armour wire layer; and

providing an outer sheath as an outer fluid retaining layer over the mount body and the tensile armour layer.

2. The method as claimed in claim 1 , further comprising;

providing the mount body over the tensile armour wire layer by locating at least two mating mount body portions over the tensile armour wire layer.

3. The method as claimed in claim 2 , further comprising:

securing the mount body portions together to form the substantially cylindrical mount body.

4. The method as claimed in claim 1 , further comprising:

wrapping a tape layer over and/or under the tensile armour wire layer and said mount body.

5. The method as claimed in claim 1 , further comprising:

providing a mark or marks on an outer surface of the outer sheath at a respective location associated with a securing element of the cylindrical mount body.

6. The method as claimed in claim 1 , further comprising:

providing the cylindrical mount body over the outer surface of the tensile armour layer whereby the mount body makes an interference fit with the outer surface of the tensile armour layer.

7. The method as claimed is in claim 1 further comprising:

providing the mount body in one or more body portions, at least one body portion comprising a metal region.

8. The method as claimed in claim 7 , further comprising providing the mount body in a plurality of body portions each wholly manufactured from a metallic material.
