Detachable ice-breaking damping device used for ocean platform

Abstract

The invention discloses a detachable ice-breaking damping device used for an ocean platform. The detachable ice-breaking damping device used for the ocean platform comprises an upper cone frustum barrel and a lower cone frustum barrel. The upper cone frustum barrel and the lower cone frustum barrel are both used for being arranged on a jacket leg of the ocean platform in a sleeved mode from top to bottom, the large-diameter end of the upper cone frustum barrel and the large-diameter end of the lower cone frustum barrel are arranged on the same horizontal plane, and the diameter of the large-diameter end of the upper cone frustum barrel is equal to that of the large-diameter end of the lower cone frustum barrel. The detachable ice-breaking damping device is not hard to build and install, convenient to detach, and capable of being reused or used for solving the problem of overhigh ice loads by being installed on an old platform, effective damping can be achieved, the damping device can be widely applied to ice-breaking structures of ocean platforms, particularly to platforms seriously affected by ice loads.

Description

technical field [0001] The invention relates to an ice-breaking device for an ocean platform, in particular to a detachable ice-breaking and shock-absorbing device for an ocean platform. Background technique [0002] In some oceans in cold regions, the surface of the sea water freezes over in winter. Sea ice drifts on the water surface under the action of ocean currents and winds, and the drifting sea ice will have a greater impact on marine engineering structures. This effect will cause vibration of the platform and accelerate the fatigue failure of the platform. In order to reduce the effect of ice load, the current engineering community adopts the measure of adding ice-breaking cones to the offshore platform. Practice has shown that this method can reduce the ice load on the offshore platform. [0003] At present, the ice-breaking cone and the jacket legs are integrally welded in the engineering. The ice-breaking cone and the jacket legs are inseparable, and more accurat...

AI Technical Summary

Problems solved by technology

[0003] At present, the ice-breaking cone and the jacket legs are integrally welded in the engineering. The ice-breaking cone and the jacket legs are inseparable, and more accurate tide level data needs to be provided in the design. Although the current engineering design can Reduce the ice load on the platform by breaking ice, but due to the large slope of the ice-breaking cone, a large part of the ice load will be transmitted to the jacket legs through the ice-breaking cone, which may accelerate the fatigue failure of the platform
