Problems solved by technology

This transfer method occupies a large area of ​​the platform, and the utilization rate of the upper space is low; because the crane needs to lift both ends of the riser, it takes a long time to position the opposite hanging and adjust the horizontal state to the vertical state, and the efficiency is not high; multi-equipment Working together is difficult

Embodiment

[0054] Such as Figure 1-6 A riser transport system is shown, including the drill floor 1, the riser clamping device 5, the riser hoisting device 11, the riser righting device 3, the riser catwalk 7, the undercarriage 8, and the riser finger beam 10 , riser crane 11, derrick 6, drill floor 1 is connected with derrick 6; riser clamping device 5 is connected with drill floor 1, riser crane 11 is connected with drill floor 1.

[0055] The riser transfer system also includes a riser 4 .

[0056] The working steps of the riser transfer system for the riser are as follows:

[0057] a. The riser crane 11 lifts the riser 4 located at the finger beam 10 of the riser 4;

[0058] b. The riser crane 11 moves to the position of the lower trailer 8;

[0059] c. The riser crane 11 lowers the riser 4 to the lower trailer 8;

[0060] d. The lower trailer 8 forms a support for the riser 4;

[0061] e. The riser crane 11, the undercarriage 8 and the riser 4 move to the riser catwalk 7;

Abstract

The invention relates to the field of engineering equipment, in particular to a marine riser transferring system. The marine riser transferring system comprises a drill floor surface, a marine riser clamping device, a derrick, a marine riser hoisting device, a marine riser righting device, a marine riser catwalk, a lower trailer, a marine riser fingerboard and a marine riser crane, wherein the drill floor surface is connected with the derrick, the marine riser clamping device is connected with the drill floor surface, and the marine riser crane is connected with the drill floor surface. The time for converting a marine riser from a horizontal state to a vertical state is saved when the marine riser is taken out through vertical storage and transferring of the marine riser; and during storage, the time for converting the marine riser from the vertical state to the horizontal state is saved, the access time of the marine riser is greatly shortened, and the purposes of reducing the cost and improving the efficiency are achieved.

Description

technical field [0001] The invention relates to the field of engineering equipment, in particular to a riser transfer system. Background technique [0002] In the oil and gas field, offshore drilling operations rely on establishing channels for drilling fluid. [0003] At present, the riser is stored horizontally on the deck outside the derrick. It is necessary to use a riser crane or a deck crane to lift the horizontally stored riser to the horizontal riser catwalk that is on the same plane as the drilling floor. The riser cat The catwalk moves up the drill floor to a fixed position, and then the floating crane system lifts one end of the riser. The catwalk cooperates with the floating crane system to adjust the riser from a horizontal state to a vertical state. The lifting system cooperates to lower the riser to the wellhead. After the drilling operation is completed, the riser also needs to be retrieved from the center of the wellhead to the storage area, and the proces...
