Over the years, Huisman has designed and delivered a large number of Flex-lay systems. The Flex-lay method combines capabilities for the installation of flexible pipelines, risers and in-line structures. The most notable features of a Flex-lay system are its vertical ramp, equipped with one or more tensioners, and a chute or wheel aligner on top.
Flex-lay systems offer an efficient pipelay method with a specific advantage: the installed pipelines are less sensitive to fatigue and therefore require less complex installation and Abandonment & Recovery procedures. Flex-lay systems are less suitable for the installation of rigid pipe, but can be adapted to perform J-lay or Reel-lay.
The large variety of Flex-lay systems we have delivered has broadened our scope of expertise, from concept design to start-up of operations. This has enabled us to easily customize and further develop Flex-lay systems for larger water depths and the handling of larger PLETs.
