Abstract
The invention belongs to deep-sea field of engineering technology, and in particular to a kind of gas curtain type drive device for suppressing deep sea vertical pipe vortex-induced vibration.The device includes perforate attachment tube, and high pressure gas pipeline, metal connecting piece, high-pressure pump, pressure charging valve, pressure sensor controls computer, optical cable.High pressure gas pipeline is connected to standpipe by metal connecting piece, and with standpipe parallel arrangement, perforate attachment tube is installed in the range of riser bottom both sides, and perforate attachment tube fumarole is upward.High pressure gas pipeline top is connected by pressure charging valve with high-pressure pump, and bottom is connected with perforate attachment tube.When having ocean current or wave passes through standpipe, high pressure draught is sprayed by bottom opening attachment tube fumarole, air-flow can form air curtain in standpipe both sides, and air curtain can effectively upset the vortex shedding that ocean current and wave cause, effectively reduce standpipe vortex-induced vibration amplitude.The present invention achievable automatic early-warning and active suppression, have good suppression efficiency to the vortex-induced vibration of deep sea vertical pipe.
Description
Technical field
The invention belongs to deep-sea field of engineering technology, and in particular to a kind of gas curtain type drive device for suppressing deep sea vertical pipe vortex-induced vibration.
Background technology
Marine riser is the important component of deepwater field development system, is the connecting pipe of offshore platform and subsea wellheads.The vortex-induced vibration produced under the external environment condition load action such as wave, ocean current is the main inducing of riser fatigue destruction.And standpipe is once destroyed, huge economic loss will be caused and trigger serious marine pollution and secondary disaster.Therefore, when standpipe is designed, vortex-induced vibration amplitude how is reduced, extends the tired service life of marine riser, be the focus of various countries' engineering circles concern.It is main using the additional vibration-repressing device on the outside of standpipe in the world at present, the formation of whirlpool is destroyed by changing works surface configuration or adding other devices on works surface, so as to suppress vortex-induced vibration, and it is less for the research of vortex-induced vibration active forewarning and active suppression.
The content of the invention
The object of the invention is directed to deep sea vertical pipe vortex-induced vibration, designs a kind of gas curtain type drive device, and the device can effectively upset ocean current and wave, effectively reduces standpipe vortex-induced vibration amplitude, realizes active suppression.
To achieve the above object, the technical solution adopted by the present invention is：The device includes perforate attachment tube, and high pressure gas pipeline, metal connecting piece, high-pressure pump, pressure charging valve, pressure sensor controls computer, optical cable.High pressure gas pipeline is connected to standpipe by metal connecting piece, and with standpipe parallel arrangement, perforate attachment tube is installed in the range of riser bottom both sides, and perforate attachment tube fumarole is upward.High pressure gas pipeline top is connected by pressure charging valve with high-pressure pump, and bottom is connected with perforate attachment tube, and along three groups of pressure sensors of riser length surface layout, pressure sensor and high-pressure pump control end are connected with control computer respectively by optical cable.When having ocean current or wave passes through standpipe, signal transmission is given control computer by pressure sensor, when pressure signal exceedes early warning value, high-pressure pump is automatically turned on, and the air pressure of rated power is input into according to pressure signal value, high pressure draught is sprayed by bottom opening attachment tube fumarole, air-flow can form air curtain in standpipe both sides, and whole vibration suppression process can realize automatic early-warning and active suppression.
