High pressure air bottle assembly mounting method for drilling ship

Abstract

The invention discloses a high pressure air bottle assembly mounting method for a drilling ship. The drilling ship has a main deck and a first lower deck, wherein an accommodation compartment is formed between the main deck and the first lower deck, a high pressure air bottle assembly is arranged in the accommodation compartment through a base, the high pressure air bottle assembly is a multi-layer arrangement mode, each layer includes multiple high pressure air bottles, the layer of high pressure air bottles close to the first lower deck are arranged on the base in a pressed mode, the layer of high pressure air bottles away from the first lower deck are correspondingly arranged on the upper layer of high pressure air bottles in a pressed mode, and tail ends of the high pressure air bottles have release ports. The mounting method comprises steps that the base is arranged on the first lower deck; the multiple layers of high pressure air bottles are sequentially arranged on the base; first ends of multiple columns of high pressure air bottles are communicated with multiple pipelines in one-to-one correspondence, and the multiple pipelines are communicated with a main pipeline; the base and the first lower deck form a first inclination angle, and the first inclination angle is greater than 1 DEG and is smaller than 3 DEG. The mounting method is advantaged in that influence of steam on reliability of target equipment can be reduced.

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...

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
