ABSTRACT:
A suppression element (1) for vortex vibrations, comprising an envelope (2) for t least partly enveloping a tubular element (100); at least one projection (3) pointing away from the envelope. The envelope is modular to form with similar suppression elements a tube (101,102), which, in operation, at least partly, envelops a tubular element (100). Also, a construction kit for a suppression system and a suppression system for vortex vibrations with at least two suppression element (1), which together form a tube, which in operation, at least partly envelops a tubular element (100), as well as an apparatus for extracting minerals with a pipeline enveloped by a suppression system are disclosed.
