There is a minimum bending radius (MBR) for all cables, whether flexible or umbilical, beyond which the cable may sustain significant damage and lose its ability to function. Subsea bend restrictors helps reduce this hazard.

Bend Restrictor Function

A polyurethane bend limiter assembly is a device which is mounted around the cable and attached to the structure so that bending of the cable will be prevented beyond the designed locking radius of the bend limiters, thus preventing the cable from overbending.

Major Features

• Interlocking male and female mouldings

• Proven polyurethane materials for the harshest environments

• Lightweight, easy and quick to install.

• Designed and manufactured according to API 17L

Application Field

Bending restrictors are primarily used in the offshore wind industry and offshore oil platforms and are designed to mechanically limit line bends beyond their permitted MBR. Typical applications include supporting flexible pipes/cables on free spans, protecting lines around other rigid structures such as PLETs, wellheads, cable joints and J/I pipe outlets. Bending limiters only provide protection when the line reaches a certain MBR.

Philson Manufacturer Advantage

The vulkollan bend limiters produced by Chinese manufacturer Philson can be used either as a standardized product for a wide range of common diameters, loads and MRB, thereby reducing lead time and increasing installation efficiency, or as a fully customized solution that allows design customization of various functions, providing customization methods to suit your specific application.
