A marine fall pipe system(100) is constructed for placing blocks of stone and/or rock(R) on a seabed(SB) and configured for suspension from a marine vessel(10). The fall pipe system comprisesa substantially tubular fall pipe(100) having an open end for discharging the blocks of rock and/or stone, and the fall pipe system comprises an opening arrangement constructed such as to allow opening the substantially tubular fall pipe to provide an intermediate opening(170) at a position along its length for discharging the blocks of stone and/or rock at said position from the fall pipe.The fall pipe may be locally discontinued by releasing one or more fall pipe segments(110) of the fall pipe,may comprisesfall pipe segmentswith weakened parts where they will break, or a fall pipe segment may be movable sidewards to provide theintermediate opening.
