An assembled truss type pile leg device

Abstract

The invention discloses an assembled truss-type leg device, which comprises a truss-type leg connected with a spud can. The truss-type leg includes three chords whose vertical sections are distributed in an equilateral triangle, and each chord The outer circumferential surface of the rod is symmetrically connected with one tooth rack in the axial direction, and at least two horizontal struts are respectively arranged on the three vertical surfaces of the chord along the length direction and are separated from each other and connected with the chord; The assembled truss-type leg device described above has at least two layers, and a connection and positioning joint for the chord is arranged between the truss-type and truss-type legs; And bolt pair composition. The assembled truss-type leg device of the present invention realizes the transformation of the integrated self-elevating truss-type pile leg into a structural form with several layers that can be assembled through reasonable segmentation, ingenious design, and scientific assembly structure. It is easy to install, safe and reliable, and has a wide range of applications.

Description

technical field [0001] The invention relates to an assembled truss type pile leg device, in particular to a truss type pile leg device for a self-elevating ocean platform. It belongs to the field of marine engineering machinery. Background technique [0002] With the development of the offshore oil industry, the jack-up offshore platform will develop into the deep water, and the environmental conditions faced by the platform will become more and more severe. As an important part of the jack-up offshore platform, the legs play an important role in supporting the offshore platform and transferring the environmental loads on the platform to the seabed. Each self-elevating offshore platform has 3 or more legs to support when the offshore platform changes the operating location, the platform needs to be towed to another location. Before towing, each leg is pulled out of the seabed and lifted above the sea level using the device on the platform, and then towed under good environ...

AI Technical Summary

Problems solved by technology

This has the following disadvantages: (1) During the towage process, the pile legs are lifted above the sea level, which is greatly affected by the environmental load and poses a great threat to the safety of the platform relocation

(2) The length and quality of the pile legs are very large, and the operation is inconvenient and dangerous when lifting the pile legs

(3) Once the design water depth of the platform is determined, the length of the pile legs is also determined. For some sea areas where the working conditions are allowed but the water depth is deeper, its operating range is limited

However, it cannot solve the current operating problems of deep-water platforms and the safety issues of platform towing.
