Self-elevating offshore platform and submersible pump tower thereof

Abstract

The invention provides a self-elevating offshore platform and a submersible pump tower thereof. The submersible pump tower comprises a tower pipe and a plurality of guide devices arranged at intervals along the height direction of the tower pipe, and a sliding groove is formed in the outer side of each guide device, so that the guide device is slidably matched with guide rails on a pile penetrating pipe. Each guide device comprises a first clamping part, a second clamping part, a fixing part and an adjusting part, each clamping part comprises a base and a breast board fixed onto the base, the base of the first clamping part is fixedly connected with the tower pipe, the bases of the two clamping parts are fixedly connected through the fixing part, the breast boards of the two clamping parts are opposite and spaced, the sliding groove is formed between the two breast boards, the adjusting part is arranged between the first clamping part and the second clamping part of each guide device to adjust the gap of the sliding groove between the two clamping parts, and the gap of the sliding groove of an overwater guide device is larger than that of the sliding groove of an underwater guide device. Further, the underwater guide device is flexibly matched with the guide rails through elastic parts. The problem of sliding clamping stagnation of the submersible pump tower is solved.

Description

technical field [0001] The invention relates to the field of ocean engineering, in particular to a self-elevating ocean platform and a submersible pump tower thereof. Background technique [0002] In order to prevent wind and waves, the main hull of the self-elevating offshore platform generally has to be about 10 meters away from the sea surface when it is working. The submersible pump is an important equipment for the platform to lift seawater to the main hull. [0003] The submersible pump is usually installed under the tower tube of the submersible pump tower, and the side wall of the tower tube is equipped with a guide device, through the chute on the guide device and the submersible pump slideway installed on the pile flushing pipeline of the pile leg (usually made of flat iron The guide rails constituted by the sliding fit, so that the tower pipe can move up and down relative to the pile pipe, so that the submersible pump is kept 1~2 meters below the sea level.
