Problems solved by technology

At the same time, the span and support strength of the original BOP lifts and suspension trolleys running on the sliding device also need to be redesigned to suit the width of the newly laid sliding device. It will greatly increase the construction cost of offshore equipment
What's more, it will constitute a safety hazard in terms of the strength of offshore equipment
In short, the use of the skid device with the existing structure and the modified moon pool will greatly increase the difficulty and cost of manufacturing offshore equipment

Abstract

The invention discloses a sliding device and a working method thereof. Through disconnecting an original fixed sliding rail on a second space which is added to a moon pool, and connecting a moving sliding rail which can move in and out of the second space, on the premise that the distance of two fixed sliding rails in a sliding device is not increased, the sliding device can be suitable to be usedon a changed new moon pool, and second modification of a BOP elevator and a suspension trolley operated on the original sliding device is prevented. A drill conductor can be adapted to working requirement of maritime equipment in severe sea conditions, and construction cost of maritime equipment is reduced, and compatibility of the maritime equipment is enhanced. The working method of the slidingdevice also has the above advantages.

Description

technical field [0001] The invention relates to the field of marine engineering equipment, in particular to a sliding device applied to the marine engineering equipment and a working method thereof. Background technique [0002] With the rapid increase in the demand for oil in production and life in modern society and the continuous development of offshore oil and gas resources, various types of marine engineering structures such as offshore drilling ships and offshore drilling platforms have emerged. The common structural feature of such marine engineering structures is that a vertical through hole from the upper deck to the bottom is set in the middle, which is called a moon pool. Generally, when it is used for underwater operations such as drilling or exploration, the riser casing is installed. , BOP and other equipment into the seabed. [0003] In order to make the offshore equipment work normally under severe sea conditions, the moon pool of the offshore equipment is c...
