Schedule of Approval

1 Product Description

Dynamic Bend Stiffener is used to prevent the overbending of the flexible pipe or umbilical under load.

There are three sections in Dynamic Bend Stiffeners:-

• The central active section, which is normally conical but may be modified to optimise the stiffness profile along the length. The diameter and length of the cone controls the loaded shape and bend radius of the stiffener and cable.

• An additional cylindrical section with a mounting flange and internal steelwork which joins the Polyurethane cone to the end fitting. For dynamic BSRs, the end fitting has a combination of an inner Tube to securely attach the Polyurethane and an outer Cage to provide extra support and reduce the stress on the Polyurethane to Steel bond at the mating flange face.

• A short straight section at the tip of the small end of the cone. This is to reinforce the thin area of the stiffener to inhibit tearing of the Polyurethane.

Dynamic Bend Stiffener is designed as per requirement of API 17L 1: 2013.

2 Application

Flexible pipes or umbilical carries high risk of overbend. Dynamic Bend Stiffener works as a sleeve to these pipes and restricts the movement. The definition of Dynamic Bend Stiffener can be summarised a shown below.

'Dynamic Bend Stiffener is a mechanical device consists of a tapered elastomeric sleeve fitted over a flexible pipe, umbilical or cable to provide extra support and prevent overbending."

Purchaser shall specify the Bend Stiffener Design parameters in accordance with API 17L 1: 2013 Section 5.2.3.

The design of Dynamic Bend Stiffener verified by Bureau Veritas under this certificate is subjected to following limitations.

10 Comments

Bureau Veritas has reviewed the design methodology adopted for Bend stiffener against the requirements stated in API 17L 1: 2013. Design methodology was found to be in compliance with API 17L 1: 2013 for Dynamic Bend Stiffeners suitable for a range of Flexible Pipe diameters.

Bureau Veritas have reviewed the Dynamic Bend Stiffener design documentation which highlights flexible pipe ID of 8" , this Parameter is not considered as a limiting factor for Dynamic Bend Stiffener design covered by this type approval. (project reference 13423, BV report 17 ABD1 0197 Rev. 0).

Bureau Veritas have also reviewed Dynamic Bend Stiffener design where Spindle & Ring Assembly and Nuts are made up of lnconel 625 UN06625 material. Independent appraisal report 17 ABD1 0375 Rev. 0 details assessment carried out to check its suitability to project specific requirements and its compliance to API 17L 1.

This type approval certificate does not cover maintenance and commissioning of the Dynamic Bend Stiffeners.

Balmoral Comtec shall demonstrate all relevant documents including design reports and calculations on a case by case basis for project specific product.
