ABSTRACT:
The present invention relates to a fluid conduit, and to a multi-conduit umbilical for use in the transportation of chemicals with small molecular size and shape e.g. methanol ethanol and other hydrocarbon fluids used in the oil industry. The conduit comprises a flexible fluid hose encapsulated by at least one metallized layer which is formed and arranged to minimize permeation of a fluid being transported in the fluid hose. In use in a multi-conduit umbilical the metallised layer minimizes permeation into adjacent fluid hoses containing chemicals. The invention is characterized in that the fluid hose(s) have differing levels of encapsulation and thereby permeation, along a given length according to the operational requirements of the fluid conduit/umbilical. Typically such fluid conduits/umbilicals will have lengths in excess of 100 km.
