ANSI API Spec 17E-2010 pdf free download.Specification for Subsea Umbilicals.
1 Scope This part of ISO 13628 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 part of ISO 13628 applies to umbilicals containing components, such as electrical cables, optical fibres, thermoplastic hoses and metallic tubes, either alone or in combination. This part of ISO 13628 applies to umbilicals for static or dynamic service, with surface-surface, surface-subsea and subsea-subsea routings. This part of ISO 13628 does not apply to the associated component connectors, unless they affect the performance of the umbilical or that of its ancillary equipment. This part of ISO 13628 applies only to tubes with the following dimensions: wall thickness, t ? 6 mm, internal diameter, ID ? 50,8 mm (2 in). Tubular products greater than these dimensions can be regarded as pipe/linepipe and it is expected that they be designed and manufactured according to a recognised pipeline/linepipe standard. This part of ISO 13628 does not apply to a tube or hose rated lower than 7 MPa (1 015 psi). This part of ISO 13628 does not apply to electric cable voltage ratings above standard rated voltages 0 m / ( ) U U U ? 3,6/6(7,2) kV rms, where U 0 , U and U m are as defined in IEC 60502-1 and IEC 60502-2. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. ISO 527 (all parts), Plastics — Determination of tensile properties ISO 1402, Rubber and plastics hoses and hose assemblies — Hydrostatic testing 3.1.5 bend stiffener device for providing a localized increase in bending stiffness, preserving the minimum bend radius of the umbilical under defined bending moment conditions NOTE The stiffener is usually a moulded device, sometimes reinforced, depending on the required duty, applied over the umbilical. It is sometimes referred to as a bend strain reliever (BSR). 3.1.6 bird-caging phenomenon whereby armour wires locally rearrange with an increase and/or decrease in pitch-circle diameter as a result of accumulated axial and radial stresses in the armour layer(s) 3.1.7 bundle laid-up functional components and associated fillers in the umbilical prior to further processing NOTE Typical functional components in a bundle include hoses, tubes, electric cables, optical fibre cables. 3.1.8 capacity curve curve that defines the relationship between the allowable bend radius and allowable tension for an internal pressure condition See Figure 1. NOTE Curves can, therefore, differ for storage, testing, installation and operation scenarios. 3.1.9 carousel storage container that can be rotated by a drive about a vertical axis 3.1.10 caterpillar device that holds the umbilical between belts or pads and which transfers axial linear motive power to the umbilical NOTE A caterpillar is also known as an in-line cable engine, or haul off, or tensioner. 3.1.11 characterization data data relating to a component or an umbilical giving an indication of performance but not giving specific acceptance/rejection criteria
3.1.12 chinese finger type of gripper used to hold the umbilical via its outer diameter, comprised of a number of spirally interwoven wires or synthetic rope attached to a built-in anchorage arrangement 3.1.13 core generic term used to describe an individual electrically insulated conductor 3.1.14 crab lay installation deployment activity whereby the installation vessel moves sideways along, or at the end of, the installation route 3.1.15 crushing load load that acts in the radial direction that might not be evenly distributed along the circumference and that is limited in length along the umbilical NOTE A crushing load is typically induced during installation.
