The invention discloses an emergency release system for an output hose and a use method thereof, which comprises an emergency release speed reduction device, the emergency release speed reduction device comprises a hydraulic winch, a mooring rope, a rigging and a hydraulic power unit, the hydraulic winch is arranged on an offshore production platform, the inner end of the mooring rope is fixed in the hydraulic winch, the rigging is arranged at the outer end of the mooring rope, The rigging is connected with the output hose, and the hydraulic power unit is connected with the hydraulic winch and drives the hydraulic winch to release and recover a cable; when the output hose is released emergently, the mooring rope and the rigging limit the free falling direction of the output hose, and the hydraulic winch limits the flow of hydraulic oil and limits the lowering speed of the mooring rope on the hydraulic winch, so that the effect of limiting the falling speed of the output hose is achieved, and the impact between the output hose and seawater is reduced; the problem that the speed is too high in the emergency releasing and falling process of the output hose is solved, the output hose and offshore facilities are prevented from being damaged, the risk of oil and gas output operation is reduced, and therefore the economic cost is reduced.
本发明公开了一种外输软管应急释放系统和使用方法,包括应急释放减速装置,应急释放减速装置包括液压绞车、缆绳、索具和液压动力单元,液压绞车设置在海上生产平台上,缆绳的内端固定在液压绞车内,缆绳的外端设有索具,索具连接外输软管,液压动力单元连接液压绞车并驱动液压绞车外放和回收缆绳;当外输软管应急释放时,缆绳和索具限定外输软管自由下落的方向,液压绞车通过限制液压油的流量,限制液压绞车上缆绳的下放速度,从而起到限制外输软管的坠落速度的作用,减小外输软管与海水之间的冲击,解决了外输软管应急释放下落过程中速度过大的问题,防止外输软管及海上设施遭受损坏,降低油气外输作业的风险,从而降低经济成本。
