Add, 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 i.e. floating
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, develops 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, as sea and seabed
A kind of contact channel, it connects seabed resources and offshore work platform, is drilled, drain, leads bricklayer's's work, 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 is consolidated with standpipe
Have frequency it is close when, the judder of standpipe will be caused, standpipe is influenced 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, it is passive suppress to be reached by varying standpipe surface configuration so as to achieve the purpose that to suppress vibration
The purpose in flow field is upset, both are combined by the present invention.The passive most shape of restraining device is fixed at present, is not adapted to multiple
