Embodiment

[0036] see Figure 1-Figure 5 , the embodiment of the present invention provides a sunken Christmas tree transport trolley, which includes an upper car body 1, a lower car body 2, a guide rail 3 and an elevator 4. Wherein, the quantity of upper body 1 is two, wherein one upper body 1 links to one side with lower body 2, and another upper body 1 links to each other with the other side of lower body 2. In use, the guide rail 3 is arranged on the main deck 7 , and the upper vehicle body 1 is slidably matched with the guide rail 3 , so that the upper vehicle body 1 can move relative to the main deck 7 . The lower body 2 is used to be placed in the moon pool 6, and the lower body 2 can move with the upper body 1 relative to the main deck 7. One end of the elevator 4 links to each other with the upper car body 1, and the other end links to each other with the lower car body 2, so that the staff can go up and down.

[0037] In this embodiment, the upper vehicle body 1 and the lower...

Abstract

The invention relates to the field of petroleum drilling and production equipment, in particular to a sunken Christmas tree moving trolley. The sunken Christmas tree moving trolley comprises an upper trolley body and a lower vehicle body, and the upper trolley body is used for being slidably connected with a main deck; and the lower vehicle body is connected with the upper vehicle body, a Christmas tree positioning device is arranged on the lower vehicle body, and the lower vehicle body is used for being arranged in a moon pool. According to the sunken Christmas tree moving trolley, the lower trolley body capable of being placed in the moon pool is arranged, the Christmas tree to be moved is placed on the lower trolley body, so that in the Christmas tree moving process, the requirement for the distance between the main deck and a drilling base can be reduced, and on the premise that the drilling base is lowered continuously and the distance between the drilling base and the main deck is smaller and smaller, the Christmas tree can be moved well.

Description

technical field [0001] The invention relates to oil drilling and production equipment, in particular to a submerged Christmas tree transport trolley. Background technique [0002] The Christmas tree is a key device for controlling and regulating oil and gas production, and it is installed on the upper part of the wellhead of the oil and gas well. Before the drilling platform is lowered, the Christmas tree needs to be moved from the end of the moonpool to the center of the wellhead. In the prior art, the Christmas tree is moved on the main deck, and during the transportation, the Christmas tree is located between the drilling base and the main deck. At present, in order to ensure the stability of the floating drilling platform, the height of the drilling base is continuously reduced, which makes the space between the drilling base and the main deck narrower and narrower, and even makes it impossible for the Christmas tree to be moved to the center of the wellbore. However, ...
