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 Terms, abbreviated terms and definitions 3.1 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1.1 allowable bend radius minimum radius to which an umbilical, at a given tension, may be bent to without infringing design criteria or suffering loss of performance See Figure 1. NOTE 1 The bend radius is measured to the centreline of the umbilical. NOTE 2 Allowable bend radius increases with increasing tensile load and varies depending on internal pressure and condition, i.e. safety level. 3.1.2 allowable tensile load maximum tensile load that an umbilical, at a given bend radius, can be loaded to without infringing design criteria or suffering loss of performance See Figure 1. NOTE Allowable tensile load decreases with decreasing bend radius and will vary depending on internal pressure and condition, i.e. safety level. 3.1.3 ancillary equipment accessory to the umbilical system that does not form part of the main functional purpose EXAMPLES Weak link, buoyancy attachments, I-tube or J-tube seals, VIV strakes, centralizers, anchors external clamps. 3.1.4 bend restrictor device for limiting the bend radius of the umbilical by mechanical means NOTE A bend restrictor typically is comprised of a series of interlocking metallic or moulded rings, applied over the umbilical. It is sometimes referred to as a bend strain reliever (BSR).
