Description
Technical field
The present invention relates to working equipment and the operational method of the processing of a kind of submerged pipeline suspended span section, particularly uphang working equipment and the operational method across submerged pipeline processing about a kind of for deep water.
Background technology
Submerged pipeline is the important component part of offshore oilfield production system, but due to the scouring a hole effect of ocean current, takes away the silt under submerged pipeline, make submerged pipeline on sea bed in vacant state. Unsettled submerged pipeline, under the washing away of ocean current and wave, produces whirlpool and swashs resonance, if the dynamic stress that this vibration causes exceedes fatigue limit, extra large pipe will produce stress in the most serious unsettled part and concentrate and produce fatigue crack. When submerged pipeline local location exceedes certain surrender Ji County, very likely fracture, causes the crude oil marine significant pollution accident such as leak outside, and not only causes sea pollution and great economic loss, also can produce severe social influence. Processing at present the unsettled method of submerged pipeline generally has throwing joint cover layer, flexible hose, throwing sand pocket to cover in conjunction with bionic aquatic weed, but exist equally defect separately, throwing engages cover layer can cannot prevent the generation that secondary washes away, and has simultaneously and again washes in a pan empty possibility, unstable; The flexible hose replacing that need to stop production, because flexible pipe franchise property is strong, cost of investment is higher simultaneously; Throwing sand pocket covers in conjunction with bionic aquatic weed the unsettled too high situation that is unsuitable for, and bionic aquatic weed franchise property is stronger, and cost of investment is higher, and simultaneously because underwater operation amount is large, the marine duration is longer. Along with offshore oil exploitation is gradually towards deep water sea area development, the geology characteristic of deep water sea area is more complicated, and deep water submerged pipeline easily occurs that suspended span is highly high, the phenomenon that suspended span length is long. Conventional submerged pipeline suspended span processing method can not economical and effectively solve the problem of uphanging across, deep water sea pipe suspended span.
Present patent application has proposed just a kind of deep water that can be used in and has uphang working equipment and the operational method across submerged pipeline processing under this background.
