ANSI API Spec 17E:2010 pdf download.Specification for Subsea Umbilicals.
3.1.28
lay-up
operation of helically assembling (SZ where appropriate) electrical cores or optical fibres into a cable, or hoses, tubes, electric cables, optical fibre cables into a bundle or sub-bundle
NOTE Sometimes referred to as “cabling”.
3.1.29
lay angle
angle between the axis of a spiral-wound element (e.g. armour wires) and a line parallel to the longitudinal axis of the umbilical
3.1.30
load-out
transfer of an umbilical or umbilical system from a storage facility onto an installation/shipping vessel, either by transfer spooling or by lifting the product stored on its installation/shipping reel
3.1.31
manufacturer’s written specification
specification for the umbilical, the umbilical components and their manufacture, generated by the manufacturer in compliance with requirements specified by the purchaser and this part of ISO 13628
NOTE The specification may be comprised of a multiplicity of documents (design plan, inspection and test plan, test procedures, etc.).
3.1.32
maximum tensile load
maximum tensile load that an umbilical, with zero curvature, can withstand without infringing the stress criterion or suffering loss of performance
See Figure 1, and 3.1.8.
3.1.33
messenger wire
device installed or pre-fitted into an I-tube or J-tube for transferring the primary pulling device, usually a wire rope, into the tube to provide means of pulling an umbilical through the tube
3.1.34
minimum bend radius
minimum radius to which an umbilical, at zero tensile load, can be bent to without infringing the stress criterion or suffering loss of performance
See Figure 1 and 3.1.8.
3.1.35
multi-coupler
multi-way connector arrangement comprised of two mating stabplate sub-assemblies, one of which is made of a number of hydraulic and/or electric and/or optical coupler halves, each carrying a separate service, that mate simultaneously with corresponding coupler halves on the other sub-assembly when the two sub-assemblies are brought together
3.1.36
pull-in head
device used for terminating the end of an umbilical so that it can be loaded/offloaded from a vessel and pulled along the seabed and/or through an I-tube or J-tube
NOTE In some designs, the terminated armours can be used to anchor the umbilical at the top of the I-tube or J-tube. It normally is comprised of a streamlined cylindrical housing into which the umbilical armouring is terminated and within which the ends of the functional components are contained. It is usually capable of rapid disassembly to access the components for post-pull-in tests and monitoring. A form of pull-in head may also be used at the subsea end of the umbilical.
3.1.37
reel
device for storing, transporting, or installing umbilicals or components comprised of two flanges, separated by a barrel, with the barrel axis normally being horizontal
NOTE Reels are designed for the intended use.
3.1.38
service life
specified time during which the umbilical system shall be capable of meeting the functional requirements
3.1.39
S-N data
data obtained by plotting cyclic stress level versus number of cycles to failure
3.1.40
splice
join together component lengths or sub-components to achieve the required production length
3.1.41
static application
application for which the load effect(s) due to dynamic loads (e.g. wave action, induced vibrations, etc.) when installed can be neglected
NOTE Free spans, in an otherwise static umbilical, should be considered as a dynamic application.
3.1.42
subsea termination interface
mechanism that forms the transition between the umbilical and the subsea termination
NOTE The interface is comprised typically of an umbilical armour termination and/or a mechanical anchoring device for the tubes, bend stiffener/limiter, and tube or hose-end fittings. If the umbilical contains electric cables/fibre optics, then penetrator(s) and/or connectors may also be incorporated.
3.1.43
subsea umbilical termination
mechanism for mechanically, electrically, optically and/or hydraulically connecting an umbilical or jumper bundle to a subsea system
3.1.44
tensile armour
structural layer consisting of e.g. steel wires, fibre reinforced plastic rods, etc. that is used to sustain tensile loads in the umbilical.
