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 minimise permeation of a fluid being transported in the fluid hose. In use in a multi-conduit umbilical the metallized layer minimises 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.
A fluid conduit for the transportation of chemicals with small molecular size and shape, eg, methanol, ethanol and hydrocarbon fluids and which is suitable for use in a multi-conduit umbilical, which conduit comprises a generally flexible fluid hose encapsulated by at least one metallised layer formed and arranged to substantially minimise permeation therethrough of fluid being transported in said fluid hose and, in use, in a multi-conduit umbilical to substantially minimise permeation into said fluid hose from adjacent hoses containing chemicals, characterised in that sections or lengths of said fluid hose have differing levels of encapsulation, and thereby permeation, along a given length thereof according to the operational requirements of the fluid conduit/umbilical.
