摘要： A marine fall pipe system (100) for placing blocks of stone and/or rock(R) on a sea bed (SB) is configured for suspension from a marine vessel (10). The fall pipe system comprises substantially tubular fall pipe segments (110) configurable to provide at least first and second fall pipe sections (101, 102) of fall pipe segments,and a suspension module (200) configured to be suspended from the marine vessel. The suspension module is configured for suspending the second fall pipe section (102) of fall pipe segments from the suspension module so as to continue the first fall pipe section (101) of fall pipe segments. The first fall pipe section (101) and the suspension module (200) with the second fall pipe section (102) are independently suspended from the marine vessel (10). The suspension module (200) may be configured for suspension by at least one chain, cable (220) or wire.

摘要： 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.
