Stinger rolls: pipe support rollers
Ridderflex covers stinger rolls with polyurethane to prevent damage on the pipe.
A stinger is essential for installation of pipelines, cables and umbilicals and is installed at the stern of a vessel. Onboard the vessel, pipe parts are welded together. The pipe is placed on the stinger and rolls over the pipe support rollers into the water.
The seagoing pipe is supported by the stinger. This way the radius can be controlled when the welded pipe bends towards the seabed during the installation phase.
