    Description

    S-Lay is most commonly used for laying concrete coated thin wall pipe in shallow water depths or thick wall polymer coated pipe in deepwater. Pipe diameters vary from small 4”NB pipe up to large 60” diameter pipe. The pipe is stored on the vessel / barge horizontally in lengths and will work its way through beveling, alignment, welding, NDT and coating workstations before exiting the vessel via an adjustable radius ‘Stinger’. The Stinger Radius prevents the pipe from yielding as it passes over the numerous Support Roller Units and the lay tension controls the pipe catenary and radius as it is deployed to the seabed, ensuring the pipe stress remains elastic, thus preventing pipe permanent deformation and buckling.
