Problems solved by technology

However, when the air dryer breaks down, water vapor easily enters or remains in the high-pressure air bottle, and the water vapor will enter the target device together with the high-pressure air, thereby affecting the use of the target device and easily reducing the reliability of the target device

Embodiment Construction

[0067] A preferred embodiment will be given below, and the present invention will be described more clearly and completely in conjunction with the accompanying drawings.

[0068] The drilling ship has a main deck and a lower deck, an accommodating cabin is formed between the main deck and the next deck, the high-pressure air cylinder assembly of the drilling ship is located in the accommodating cabin, and the next deck is provided with There is a base, and the high-pressure air bottle assembly is pressed on the base.

[0069] Wherein, the high-pressure air bottle assembly is arranged in multiple layers, each layer of the high-pressure air bottle assembly includes a plurality of high-pressure air bottles, and one layer of high-pressure air bottles close to the bottom plate in the multi-layer high-pressure air bottle Set on the base; among any adjacent two layers of high-pressure air bottles, one layer of high-pressure air bottles away from the bottom plate is pressed one by one...

Abstract

The invention discloses an installation method for a high-pressure air cylinder assembly of a drilling ship. The drilling ship has a main deck and a lower deck, and an accommodating compartment is formed between the main deck and the next deck. The high-pressure air bottle assembly is arranged in the accommodating cabin through the base. It includes a plurality of high-pressure air bottles, and the high-pressure air bottles on the next deck are pressed on the base; the high-pressure air bottles on the next deck are correspondingly pressed on the upper layer of high-pressure air bottles; the tail ends of the high-pressure air bottles have vent. The installation method includes the following steps: setting the base on the next deck; setting the multi-layer high-pressure air cylinders on the base in turn; It communicates with the main pipeline; the base forms a first inclination angle with the next deck, and the first inclination angle is greater than 1° and less than 3°. This installation method can reduce the impact of water vapor on the reliability of the target device.

Description

technical field [0001] The invention relates to the field of shipbuilding, in particular to a method for installing a high-pressure air bottle assembly used in a drilling ship. Background technique [0002] Offshore drilling operations are done by offshore drilling platforms or drilling ships. Unlike land drilling operations, offshore drilling operations are affected by the ocean, such as waves, which can cause horizontal and vertical movement of the ship. Among them, in order to solve the vertical movement of the ship caused by waves, in the process of oil drilling, it is usually necessary to install two types of equipment, the crown block and the tensioner, respectively for the top drive (the driving device of the drill pipe), the riser (the drilling The rod is separated from the seawater and forms a mud circuit) for heave compensation, and the power of the crown block and the tensioner is high-pressure air, which comes from a high-pressure air bottle. The working pressur...
