Bend Restrictors (BR) are designed to prevent over-bending of flexible pipes/umbilicals/cables at the interface with rigid structures.

DESIGN

Our Bend Restrictors are made of fully qualified and field proven rigid Polyurethane (PU) System (Bardeep UR 1500 Med), dedicated for extreme subsea loading applications. Our technical PU system allows significant weight in water and air reductions on the BR systems.

Composed of interlocking elements, each made of half shells bolted together with high grade stainless steel fasteners, our Bend Restrictor provides protection from over-bending when the Minimum Bending Radius (MBR) is achieved. Connections to the rigid structure can be done through machined steel reaction collars or casted and machined PU end fittings.

Our Bend Restrictors are designed through FEA, and thermal analysis can also be performed in case of high operation temperature. In case of high external flexible temperature, an internal thermal protection shield can be added on the Bend Restrictors.

Design specifications

Our Bend Restrictors are designed with our own developed calculation software, fully compliant with the last API 17 L1 and L2 revision (March 2013), and with the following information:

- Flexible pipe/Umbilical/Cable OD & Tolerances

- Flexible pipe/Umbilical/Cable technical datasheets

- Minimum Bending Radius (MBR) under load - Shear Force (Installation & Operation) - Bending Moment (Installation &

Operation) - Flexible Pipe operation temperatures &

Thermal conductivity - Air & sea-water temperatures - Required coverage (Angle and/or Length) - Service Life - Interface / Support structure details

FAT/TESTS

A fully destructive test, witnessed by a third party has been performed to validate & qualify our design methodology with all major Flexible Pipes/Umbilical/Cable manufacturers.

Our Bend Restrictors are systematically fully scale tested (Fit-Up & Loading test) prior to delivery on site. Bend Restrictors loading tests are available at all our manufacturing locations around the world.

The Piggyback blocks allow a secondary line to be secured onto a main pipeline, and maintain a precise clearance between the two lines.

DESIGN

The main function of the Piggyback Blocks is to allow the installation of a secondary line onto a main pipe. To avoid any contact, lashing, or thermal interaction between the “piggybacked” line and the main pipe, the Piggyback Blocks are designed to maintain a precise clearance between these two lines.

A wide range of strapping solutions ensure that the piggyback block is firmly clamped onto the main pipe, and that no sliding will occur during the installation & service life of the product.

Furthermore the Piggyback Block solution developed by BARDOT Group is designed for over 30 years service life, without requiring any maintenance thanks to the use of field proven materials.

The Piggyback blocks are composed of:

• One main block made of high performance polyurethane, or reinforced polypropylene, depending on project requirements.

• A strapping system designed to fit with project needs, and usually made of alloy or composite material.

• Fasteners for specific cases, always made of material highly resistant to marine corrosion.

• Elastomeric pad to increase the clamping capacities, and improve the fitting of the Piggyback Block onto the main pipe.

• Adaptive spacers to allow a localized clearance modification and accommodate a local pipe diameter change (tie-in flange, coating modification, etc.)

manufacturingThanks to various manufacturing sites all over the world, BARDOT Group is able to produce the Piggyback Block solutions close to where it is requested, and helps you to optimize your project logistic and local content.

Our expertise in the composite manufacturing allows us to reach high production capacities and flawless product quality, to deliver timely the best product to our clients.

Shrouds are used to smoothly raise a pipe when laying through the stinger rollers in order to prevent damage of an in-line structure.

DESIGN

To achieve a regular ramp, two kinds of shrouds are successively installed on each side of the structure: tapered and straight shrouds.

Our Shrouds are a field proven solution to install heavy in-line structures. Thanks to their high mechanical properties, our Shrouds are able to sustain great stresses from the roller boxes and limit the loads applied to the line, especially on the stress joints.

Each shroud envelops the pipe and gradually fills the geometrical gap between the in-line structure OD and the pipe OD to ensure a smooth laying.

The Shrouds are made of fully qualified Bardeep PUR 80, a 95 ShoreA Polyurethane system. This polyurethane is exhibiting high compression properties, and able to undertake the significant stresses of pipe laying.

Every shroud is shaped with a groove at each end (respectively male and female) to allow a rigid connection between neighbouring shrouds, and the clamping of the shroud onto the pipe is ensured by high capacity Kevlar straps, tightened with corrosion resistant alloy fasteners.

manufacturing

BARDOT’s specialized manufacturing sites for shrouds are located in Italy and Houston, and are experts with the manufacturing of such critical equipments. Extensive full scale tests are performed in our facilities, to simulate the stress exerted by the stinger’s rollers both in dynamic and static cases, to ensure the fitness for purpose of the designed Shrouds.
