API Spec 17E

This document specifies requirements and gives recommendations for the design, material selection, manufacture, design verification, testing, installation, and operation of umbilicals and associated ancillary equipment for the petroleum and natural gas industries. Ancillary equipment does not include topside hardware. Topside hardware refers to any hardware that is not permanently attached to the umbilical, above the topside hang-off termination.

This also applies to umbilicals containing components, such as electrical cables, optical fibers, thermoplastic hoses, and metallic tubes, either alone or in combination. The document also applies to umbilicals that are for static or dynamic service, with surface-surface, surface-subsea, and subsea-subsea routings. Tube dimensions addressed by this document are wall thicknesses less than 6 mm (0.2 in.) and internal diameters less than 50.8 mm (2 in.). This document applies to electrical cables for rated voltages from 1kV (Um = 1.2kV) up to 30kV (Um = 36kV).

This document does not apply to the associated component connectors, unless they affect the performance of the umbilical or that of its ancillary equipment. It also does not apply to a tube or hose rated lower than 7 MPa (1015 psi).
