摘要： A marine fall pipe system is constructed for placing rock on a sea bed. The fall pipe system comprises a substantially tubular fall pipe, wherein the fall pipe system comprises buoyancy provided such as to, during use, be arranged along the fall pipe so as to at least partially compensate for a weight of the fall pipe system. The buoyancy is preferably provided such as to, during use, being distributed along the fall pipe. The fall pipe system comprises substantially tubular fall pipe sections for making up the fall pipe, the buoyancy being associated with one or more fall pipe sections, and the one or more fall pipe sections with associated buoyancy comprise integral buoyancy. The buoyancy is provided by microspheres integrated in the fall pipe section(s), the microspheres comprising hollow microspheres, especially hollow glass microspheres. The fall pipe sections may comprise bottomless buckets having a top side and a bottom side, an external perimeter of the bottom side being smaller than an internal perimeter of the top side, a top side of one fall pipe section overlapping a bottom side of an adjacent fall pipe section.
