Seaflex Use of Buoyancy for Installation of HDPE Pipelines Application Note

World-class Mono Buoyancy Units, trusted by contractors around the globe

Every year, Seaflex gets involved in supplying our Mono Buoyancy Units for more and more HDPE pipeline projects around the world.

Because HDPE pipe is intrinsically buoyant and offers more than enough reserve buoyancy to support the concrete collars when the ends are capped, it may not always be apparent that the use of additional buoyancy units can be a vital part of this process when it comes to the easy positioning and joining of multiple pipe strings.

Unique Group’s Seaflex have more than 30 years’ experience of supplying inflatable buoyancy solutions for offshore engineering projects – most notably where the pipeline crosses shore, either afloat or pulled along the bottom. All our bags are designed and manufactured in full compliance with IMCA D-016 guidelines, and those units we can drop-test come with type test certificates proving that they meet the required 5:1 factor of safety. Within our rental pool, all bags are inspected, tested and recertified between each and every job, and each bag comes with its own logbook demonstrating that servicing regime and also providing full traceability down to the component level for our customers’ peace of mind.
