ABOUT HUISMAN We are Huisman. We design and manufacture heavy construction equipment for the world’s leading companies in the renewable energy, oil and gas, civil, naval and entertainment markets. Our products range from Cranes, Pipelay Equipment, Drilling Equipment and Winches, to Vessel Designs and Specials. The history of Huisman is one of setting new industry standards. Of making impact, since 1929. With step changing technical solutions that vary from stand-alone to highly engineered integrated systems. From concept to installation and lifetime support. In these times of transition,...

GENERAL INTRODUCTION Huisman is a worldwide market leader in the turnkey delivery of deepwater pipelay systems. We deliver dedicated systems such as Flex-lay systems, S-lay systems, J-lay systems and Reel-lay systems. We also deliver combined systems such as the Multi-lay systems. In addition to fully integrated pipelay systems, we can also provide a full package of related standalone equipment such as baskets, reel drive systems, etc. The complexity of our projects and their innovative character require solution-oriented thinking, technical excellence, creativity and a drive for...

FLEX-LAY SYSTEMS Over the years Huisman has designed and delivered a large Flex-lay systems offer an efficient pipelay method with a number of Flex-lay systems. The Flex-lay method combines specific advantage: the installed pipelines are less sensitive capabilities for the installation of flexible pipelines, risers to fatigue and therefore require less complex installation and and in-line structures. The most notable features of a abandonment and recovery procedures. Flex-lay systems Flex-lay system are its vertical ramp, equipped with one or are less suitable for the installation of rigid...

J-LAY SYSTEMS J-lay is used to install subsea rigid pipelines in deep water. With a installation (on the seabed). This reduced amount of bending J-lay system pipe stalk, consisting of up to six pipes with a total is beneficial for installing pipelines that are sensitive to fatigue. length of 72m, are upended and welded to the seagoing pipe in Compared to other lay methods, J-lay has a relatively low a near vertical ramp. production rate due to the limited number of workstations. The J-lay method is less suitable for shallow waters as this requires a The ramp angle is adjusted so that it is...

S-LAY SYSTEMS With the S-lay installation method, pipe joints are welded onboard, leave the vessel horizontally and are guided by a stinger; a pipe supporting structure that is supported behind the vessel and controls the bend radius of the seagoing pipe string to prevent excessive bending. Due to the high production rate and the possibility to install concrete coated pipe, S-lay is extremely suitable for pipe installation in shallow and intermediate water depths. Larger water depths are also possible, but require a relatively long stinger and a large vessel to support it. An example of a...

REEL-LAY SYSTEMS Another method for the installation of rigid subsea pipelines The major advantages of Reel-lay are the high production rate is by Reel-lay. Long pipe segments are welded, tested and as well as the controlled welding and inspection conditions coated onshore and then spooled onto a large, usually vertically onshore. These advantages make Reel-lay an extremely oriented pipe reel, in one continuous length. Once the Reel-lay efficient method for the installation of pipelines in all water vessel is in position, the pipe is unspooled, straightened and depths. To make Reel-lay...

MULTI-LAY SYSTEMS Pipelay contractors more and more often decide to combine pipelay methods onboard one vessel as the infrastructure of an oil and gas field often consists of different types of pipe that require different lay methods. This 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...

MORE OPTIONS Pipelay systems can be enhanced with SMALL SYSTEMS other capabilities such as deep water Huisman has developed a range of small pipelay systems that lowering and handling of subsea modules can be easily transported and mobilised on relatively small for well servicing. The functionalities can be vessels that are available on the local market. The systems can combined without compromise because be disassembled in parts that can be transported by road. The the Huisman tensioners, either retractable systems can also be delivered as fully containerised versions. or fully opening,...
