Description
Technical field
It is more particularly to a kind of to assemble revolving for rotary blade the present invention relates to a kind of sea oil drilling and production equipment technology field
Vortex-induced vibration of marine riser restraining device and method.
Background technology
Because production needs, Offshore Oil Industry builds production system towards deeper marine site.With the increasing of the depth of water
Plus, the platform of conventional fixed-type has not adapted to this deep-sea engine request, the substitute is FPSO, semisubmersible platform,
Tension leg platform (TLP) and Spar platforms etc..Wherein, FPSO (FloatingProductionStorageandOffloading) is to float
Formula produces storage and offloading device, and preparatory processing can be carried out to crude oil and is stored, is referred to as " offshore oil factory "；Semi-submersible type drilling well
Platform, also known as column stable drilling platforms, be most of floating body not in underwater a kind of small-waterplane-area portable drilling well
Platform, is developed from bottom founded rig；Spar platforms are open side type platform.
No matter which kind of platform, marine riser is the main connector between sea and subsea wellheads, is used as sea and seabed
A kind of contact channel, it connects seabed resources and offshore work platform, is drilled, drain, leads bricklayer's and make, for grinding for standpipe
Study carefully the pith in always ocean engineering field.The marine environment load that standpipe is born mainly have wind, wave, stream, ice and
Seismic (seismal etc., its Wave and ocean current are most important ocean load.When wave and ocean current flow through standpipe, in certain stream
Under the conditions of speed, strong whirlpool can be alternately formed in standpipe both sides, what vortex shedding can be to standpipe generation a cycle can
Variable force so that with flowing to oscillation crosswise is occurring for standpipe in vertical direction, i.e. vortex-induced vibration, when vortex shedding frequency and standpipe are solid
When having frequency close, the judder of standpipe will be caused, standpipe is influenceed that its service life can be substantially reduced for a long time by vortex-induced vibration.
To reduce influence of the vortex-induced vibration to marine riser, common method is to install vortex-induced vibration suppression device, whirlpool exciting
Dynamic restraining device is broadly divided into active suppression and passive two kinds of suppression.Active suppression is by applying external energy to flow field, disturbing
Flow field around random standpipe, so that the purpose for suppressing vibration is reached, it is passive suppress to be reached by changing standpipe surface configuration
The purpose in flow field is upset, both are combined by the present invention.The passive most profile of restraining device is fixed at present, is not adapted to multiple
The marine environment of miscellaneous flow direction, how adapting to various complex fluid environment and being readily disassembled installation is current vortex-induced vibration suppression device
The focus of research.Another patent of invention that I declares, Patent No. CN201510079398.7, patent name is《It is a kind of
Vortex-induced vibration of marine riser restraining device》, it is arranged on marine riser, including V-arrangement front console and tail fin formula radome fairing, institute
The one side that V-arrangement front console is flowed to above marine riser to ocean current is stated, the tail fin formula radome fairing is vertical installed in ocean
The one side flowed on pipe back to ocean current；The cross section of the V-arrangement front console is V-shaped, and with the surface of the marine riser
It is tangent.The beneficial effects of the invention are as follows：The V-wing plate installed on V-arrangement front console, can do pendulum by a small margin with current
It is dynamic, while guiding carrys out flow point and dissipated, it can reduce to flow the resistance to marine riser, provide for a kind of solution.
