Installation method of marine drilling platform pipe arranging machine

Abstract

The invention provides an installation method of a marine drilling platform pipe arranging machine. The pipe arranging machine comprises an upper pulley, a lower pulley and a stand column. The installation method comprises the steps that the upper pulley is installed on a derrick, the lower pulley is installed on a main hull deck of in a drill pipe stand area, and the upper pulley and the lower pulley can slide in parallel in the same direction of the port side and the starboard side; a connecting tool is fixedly mounted on a sliding path of the lower pulley on the main hull deck of the drillpipe stand area, wherein the height of the connecting tooling is smaller than the height of the lower pulley; the stand column is integrally lifted and tilted and then sent to the derrick from an opening of the derrick, and then the stand column is integrally lowered to enable the lower end of the stand column to be sent into the drill pipe stand area and rotatably connected to the connecting tool; the stand column is adjusted to be in a vertical state by using the connecting tool as a fulcrum; and the connection between the stand column and the connecting tool is released, the connecting toolis removed, and the upper end and the lower end of the stand column are separately connected with the upper pulley and the lower pulley.

Description

technical field [0001] The invention relates to the technical field of ocean engineering, in particular to a method for installing a vertical pipe-laying machine for an ultra-deep water ocean drilling platform. Background technique [0002] As we all know, the offshore ultra-deepwater drilling platform has a complex system, a large number of equipment, and a single piece of equipment is heavy. The installation and commissioning of equipment is a very big challenge. Among them, there are 2 vertical pipe-laying machines for the seventh-generation ultra-deepwater drilling platform. It mainly consists of upper block and track, lower block and track and column. Its main column is about 43 tons and 43.7 meters long. Installed in the drill pipe stand area at the stern of the platform, the bottom is connected to the main hull, and the upper part is connected to the derrick. Its function is to vertically arrange drill pipes or casings in conjunction with other pipe arrangement equ...
