Line buckling - Sleepers

subsea umbilicals risers & flowlines

BARDOT Sleepers are designed to provide a dedicated location for pipeline buckling occurrence.


BARDOT Sleepers, are made of HDPE pipes, provide a safe and controlled environment for the pipeline buckling occurrence. Buckling can generate extreme damages to pipes if not assessed during design and controlled during operations. BARDOT Sleeper’s friction coefficient ranging from 0,15 to 0,08 with steel and concrete coated pipes ensures that the buckling will appear on the section of the pipe laid on the sleepers.

BARDOT Crossings and Sleepers are extruded out of high grade HDPE raw material. Length, thickness and OD can be adjusted to fit the specifications. BARDOT team of engineers runs FEA to ensure BARDOT Crossings and Sleepers are designed to withstand the installation loads and the weight of the pipes for its entire lifetime.

Our Crossings and Sleepers are made of non-corrosive materials and therefore do not require any protection nor intervention over their lifetime.

Pipes are usually much easier to store, as they can be stacked together.

Installation of BARDOT Crossings and Sleepers is also faster and cheaper than other standard solutions thanks to their light weight and pipe shape.
