STINGER ROLLS: PIPE SUPPORT ROLLERS

RAAH SAFETY - 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. Ridderflex covers these rollers with polyurethane to prevent damage on the pipe.

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.
