Apparatus for providing a thermal insulation layer in a flexible pipe, including one or more encapsulated regions of aerogel material disposed in a layer of flexible pipe body is disclosed. In addition, flexible pipe body including such apparatus, and a method of manufacturing flexible pipe body is disclosed.

Flexible pipe including thermal insulation

An apparatus for providing a thermal insulation layer in a flexible pipe includes one or more encapsulated regions of aerogel material disposed in a layer of flexible pipe body and a helically wound tape layer having a valley region and hook region that interlock adjacent windings. In addition, a method of manufacturing flexible pipe body includes providing one or more encapsulated regions of thermally insulating aerogel material.

Apparatus and methods are disclosed relating to flexible pipe and composite tape. Flexible pipe body for a flexible pipe comprises an internal pressure sheath and at least one armor layer over the sheath comprising a wound tape of composite material. A method for manufacturing a composite tape is disclosed making use of a pultrusion process.

Flexible pipe

A flexible pipe body and method of producing a flexible pipe body are disclosed. The flexible pipe body includes an inner fluid retaining layer; an armour layer provided radially outwards of the inner fluid retaining layer; and a buoyancy layer including a plurality of discrete elongate buoyancy elements provided radially outwards of the fluid retaining layer wound at a helical pitch angle equal to or more than 0 degrees and less than about 85 degrees to the longitudinal axis of the flexible pipe body.

A method and apparatus are disclosed for dissipating heat from a region of flexible pipe covered by a bend stiffener. The method includes the steps of, via at least one channel in an outer surface around a flexible pipe, providing a flow path for water to flow from a region of the flexible pipe covered by a bend stiffener to an uncovered region of the flexible pipe.
