Description
Technical field
The present invention relates to operation on the sea technical field more particularly to a kind of anti-wave stabilising arrangements of floating type offshore platform.
Background technique
Offshore work platform can be used for the work such as oil drilling, oil gas exploration exploitation, due to the changeable of sea climate and
The continuous impact of marine surge, the stability of offshore work platform and safety are particularly important.Current operation on the sea is flat
The floating platform that platform mostly uses expands the use scope of platform.
Platform is generally fixed on sea using support column by shallow sea with floating platform, however, due to by sea beat
It influences, support column has biggish unstability；If branch can not then be arranged in addition, needing to carry out operation on the sea at deep-sea
Dagger.
In general, in no surge impact, the gravity balance between two forces of buoyancy suffered by platform and itself；In sea
Wave impact lower platform can shake, translate, is unstable.Specifically, it please refers to shown in Fig. 1, is each particle stress signal in wave
Figure, the characteristic of unrestrained wave existing shear wave in communication process of wave have the characteristic of longitudinal wave again；As a result, the unrestrained wave of wave touch it is flat

Four, the upper and lower, left and right arrived power F1, F2, F3, F4, the movement of particle 23-2 can be analyzed to move up and down (reaction lateral wave
Energy) and move forward and backward (energy of reaction longitudinal wave).Wherein, when moving upwards, kinetic energy is gradually reduced in energy, is converted into gesture
Can, after peaking, potential energy is gradually converted into kinetic energy again；The kinetic energy is divided into two parts: a part travels forward, a part
It moves downward, the part to travel forward will push the particle of front, be ultimately applied to platform；Before the kinetic energy moved downward will drive
One particle moves up and down, and is eventually converted into the power of impact platform.The kinetic energy (moved forward and backward) in transverse energy generates platform
One motive force shakes platform, generates translation.Existing floating platform reduces wave rushing for platform by spring
It hits, but longitudinal impact force can only obtain buffering, converts kinetic energy into the elastic potential energy of spring.But at next moment, spring
At the time of elastic potential energy discharges, the impact platform that also will be slow.Although maximum force reduces, the action time of power is lengthened
, so momentum is totally constant, i.e., the movement of platform is still resulted in there is no reducing for the impetus of platform.It can be seen that mesh
Preceding offshore drilling platform is still larger by the impact of marine surge, fully relies on the power on platform to balance；Cause to put down
