Background
In deep sea oil projects, riser installation requires special deep sea drillships to operate, particularly ultra-deep water projects with water depths of 1785 meters to 2030 meters, such as the british oil Block 31 (31 Block) project in 2012, and particularly requires a new generation of drillships. However, even the new generation of drill ships do not perform all operations smoothly. Either a specific drill ship is selected or technical modifications are made to the drill ship that can be obtained. The booking of the operation cycle of a drill ship generally requires a very long time ahead, so that for most cases the selection of a particular drill ship is economically not advisable. Only with the technical improvements available to drilling vessels can work economically and efficiently.
In the prior art, a spider disc on a drilling ship adopts a structure with four buckles, a vertical pipe penetrates through the center of the spider disc, and the outer wall of the vertical pipe is clamped by the buckles. Although this configuration is simple and efficient and provides for easy installation of a typical riser, the design can cause problems with complex risers, such as when the auxiliary riser and riser are installed simultaneously, e.g., the snap fit can interfere with the auxiliary riser and possible damage to the auxiliary riser during installation.
The reason is that the complex vertical pipe is not only provided with one pipeline, but also provided with an auxiliary vertical pipe with a smaller diameter outside the main vertical pipe, the strength of the auxiliary vertical pipe is far lower than that of the main vertical pipe, the buckle is firstly clamped on the outer wall of the main pipe, and the auxiliary vertical pipe is arranged at present, and if the buckle is clamped on the auxiliary vertical pipe, the auxiliary vertical pipe can be damaged.
