The pipeline from the vessel to the seabed takes an S-shape that is why we call the method S-Lay. This type of installation requires an S-Lay vessel, which is basically a floating welding factory, where pieces of 12 m long pipes are continuously joint and lowered to the seabed. The pipeline from the vessel to the seabed takes an S-shape that why we call the method S-Lay For this type of installation requires an S-Lay vessel, which is basically a floating welding factory, where pieces of 12 m long pipes joint to form the pipeline and lowered to the seabed (Fig. The S-Lay method is used for pipelines with diameters from 10 to 30” in water up to 5000 m. Reel-Lay: very fast, Reel-Lay vessel, up to 12 inches, up to.J-Lay: slow, J-Lay vessel, 10-30 inches diameter, 50-5000 m deep.S-Lay: fast, S-Lay vessel, 10-30 inches diameter, 50-5000 m deep.NFL footage © NFL Productions LLC.There are four pipeline installation methods: All other NFL-related trademarks are trademarks of the National Football League.
