Problems solved by technology

However, the existing locking mechanisms are all fixed installations, that is, collision or extrusion occurs between the locking mechanism and the pile legs under the impact of sea waves, etc., so that the pile legs are stressed unevenly, so that the pile legs are deformed, and there is a huge problem. security risks

Abstract

The invention discloses a safe floating mechanism for an offshore platform and a lifting system of the offshore platform. The safe floating mechanism comprises a locking pin assembly and a floating base. The locking pin assembly is mounted in the middle of the floating base. The safe floating mechanism further comprises a plurality of buffer devices and a plurality of guide plates. The buffer devices are mounted at the upper end and the lower end of the floating base, and the guide plates are bolted to the left side and the right side of the floating base. The safe floating mechanism for the offshore platform is suitable for the hydraulic pin type lifting system of the offshore operation platform and is used for locking a pile leg and achieving a radial restraining and fastening effect on the pile leg to ensure uniform distribution of a load. Compared with a pin mechanism fixedly mounted in a pile fixing frame (7), by adoption of the safe floating mechanism for the offshore platform, collision deformation between a locking pin shaft and the pile leg is avoided, the safe reliability is improved, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of marine engineering, in particular to a safety floating mechanism for an offshore platform and a lifting system thereof. Background technique [0002] All offshore work platforms need to use a lifting system to drive the legs of the platform to move up and down to realize the lifting of the offshore work platform. When the offshore operation platform reaches the working position, lower the pile legs, lift the offshore operation platform to the specified height on the sea surface and then ballast, so that the pile legs are firmly positioned on the seabed; when the operation is completed and return to the voyage, lower the offshore operation platform to the sea level , pull out the legs, and keep the legs up during the return voyage. Due to the complex and changeable offshore environment, the offshore operation platform is subject to wind current, ocean current impact and ups and downs at any time. Therefor...
