DEVICE AND METHOD FOR CUTTING ROPE MOVING FROM FLOATING VESSEL Russian patent published in 2021 - IPC B63B21/22 

FIELD: transportation.

SUBSTANCE: group of inventions can be used in floating vessels carrying large cargo, for example, during towing, anchoring, trawling or seismic surveys. In order to avoid causing harm to personnel or a vessel, it may be advisable to release cargo by cutting a rope. Device (1) for cutting a rope moving from a floating vessel containing deck (300) contains two guide pins (2a, 2b) made with the possibility of moving between a retracted position and an extended position. A gap between guide pins (2a, 2b) in the extended position is blocked by distancing part (4). Distancing part (4) forms reaction surface (5). Cutting device (6) installed between specified two guide pins (2a, 2b) is made with the possibility of moving between the retracted position and the extended position. Cutting device (6) is made with the possibility of directly cutting a rope with a support on reaction surface (5) without holding the rope before cutting in such a way that the rope can be cut directly and regardless of the rope orientation. In a method for mechanical cutting of a rope moving from a floating vessel, by using above-described device (1), guide pins (2a, 2b) are retracted to form a closed area around the rope, the rope is cut with a support on distancing part (4), using cutting device (6), without holding the rope before cutting in such a way that the rope is cut directly and regardless of the rope orientation.

EFFECT: design of the device reduces the risk of damage to the vessel and/or the risk of human casualties.
