Huisman is a world market leader for turnkey delivery of deepwater pipelay systems.
We deliver integrated systems such as Flex-lay systems, S-lay systems, J-lay systems, and Reel-lay systems, as well as combinations of these lay methods: the Multi-lay systems. In addition to fully integrated pipelay systems, we can also provide a full package of related stand-alone equipment such as reel drive systems, askets, A&R systems, etc.
Generally, the complexity of our projects and their innovative character require solution-oriented thinking, technical excellence, creativity and a drive for innovation. This is why we not only provide standardized pipelay systems, but also highly customized pipelay systems. By closely cooperating with our clients we can meet client specific lay requirements and create the pipelay systems of the future, equipped for deeper waters and higher capacities.
Flex-lay can be used for the installation of flexible flowlines, risers and umbilicals in deepwater. We have delivered several complete Flex-lay systems, including tower structures, tensioners, A&R winches and sheaves, hang-off clamps, upper & lower chutes, reel drive units and power and control systems, for some clients in combination with other pipelay systems.
Due to its high production rate, Reel-lay is an extremely efficient method for the installation of pipelines up to 20 inch in all waters. Huisman is experienced in delivering complex Reel-lay systems including main and piggy-back reels, deepwater winches, traction and storage winch combinations, tensioners, drives and supporting cranes.
Due to its high production rate and the possibility to install concrete coated pipe, S-lay is extremely suitable for pipe installation in shallow and intermediate waters. Huisman has delivered complete S-lay systems as well as loose equipment such as stinger handling systems and pipe conveyors.
The J-lay method is intended for deepwater pipeline installation. We have solid experience in delivering complete J-lay systems - from concept design to start-up of operations - including tower structures, tower angle adjustment systems, pipe handling equipment, line-up systems and the control system commissioning onboard.
The combination of various lay methods onboard allows for large flexibility and cost efficiency as one vessel is capable of operations in most water depths and is equipped with the most cost-efficient installation method for the specific pipe.
One of our Multi-lay systems, onboard Subsea 7’s Seven Seas, features a single firing line - combining Flex-lay, J-lay and Reel-lay – and has been awarded the Maritime Innovation Award 2008.
