Problems solved by technology

[0020] 3. In the prior art, when the blowout preventer group is moved through the cooperation of pulleys and guide rails, the blowout preventer group is prone to rollover on the guide rail due to the movement of the hull with the water surface
[0021] 4. When the blowout preventer group is transported, it is easy to be damaged due to collision with the hull

Embodiment 1

[0077] Such as Figure 1 to Figure 17 As shown, the deep sea floating drilling BOP storage and transportation device of the present invention includes a base body 1, the base body 1 is welded by two side box girders 1a and a rear end box girder 1b, and the whole is a "C" shaped cross section, or " A tensile body with a “door” cross-section. After welding, the middle part of the substrate 1 forms a cavity that can accommodate the BOP frame 13. The BOP is loaded in the BOP frame 13 and can be hoisted into the cavity from above the substrate 1 to realize loading. and storage. The two side box girders 1a and one rear box girder 1b are not completely closed in cross section, forming a structure with an open front end, which can be reserved as a channel for the riser 12 to move out of the base 1 from the side.

[0078] The rear-end box beam 1b is provided with a mobile walking platform 11, which can be used as a temporary passage. After the operator goes up to the mobile walking pl...

Embodiment 2

[0096] This embodiment is an embodiment of the deep-sea floating drilling BOP storage and transportation device under storage conditions.

[0097] In the storage working condition, the deep-sea floating drilling BOP storage and transportation device needs to be parked stably on the guide rail 3a on the hull, and the storage working condition usually occurs during drilling waiting and towing.

[0098] Such as Figure 1 to Figure 3 As shown, in the storage working condition, the working status of the main components on the deep sea floating drilling BOP storage and transportation device is as follows: the hydraulic lock pin 7 is inserted into the preset pin hole on the hull, the support device 5 is retracted inside the base body 1, The clamping device 6 is in a retracted state, that is, the adjusting screw on the clamping device 6 and the operating platform 8 are in a non-working state in the vertical direction.

[0099] By fixing the hydraulic lock pin 7 in the preset pin hole...

Embodiment 3

[0107] This embodiment is an embodiment of the deep-sea floating drilling BOP storage and transportation device under pressure test conditions. The pressure test must be carried out before lowering the BOP to ensure that the BOP can work safely.

[0108] Such as Figure 7 and Figure 8 As shown, before the pressure test condition, the working status of the main components on the deep-sea floating drilling BOP storage and transportation device is as follows: the hydraulic lock pin 7 is inserted into the preset pin hole on the hull, the support device 5 is in the extended state, And hold up the BOP frame 13, the clamping device 6 is in the extended state to clamp the BOP frame 13, and the operating platform 8 is in the vertical non-working state.

[0109] The operation method of carrying out the pressure test using the BOP storage and transportation device for deep-sea floating drilling in this embodiment is as follows:

[0110] a. Adjust the adjusting screw 6b of the clampin...

Abstract

The invention discloses a BOP (blowout preventer) storage and transportation device for a deep sea float type drilling well. The BOP storage and transportation device comprises a basal body, which is formed by welding two side box type beams with a rear end box type beam. The basal body is provided with a space for accommodating a BOP, a driving device and a guide device are arranged on the basal body, the guide device comprises a guide rail arranged on the deck of a vessel body, and the basal body is provided with a pressure test device; and according to the BOP storage and transportation device, the BOP can be stored through the movable basal body, compared with the method that the arrangement of a fixed BOP storage zone on the deck is required for storing the BOP in the prior art, a BOP storage position is more flexible, during the working processes of well drilling waiting, towing and the like without the participation of the BOP, if the BOP stored on the deck intervenes the arrangement of other devices, the position of the basal body can be conveniently adjusted, a fixed occupied area is saved for the deck, and a larger and more flexible designing area is provided for the deck.

Description

technical field [0001] The invention relates to a device for storing and transporting a blowout preventer, in particular to a deep-sea floating drilling BOP storage and transport device. Background technique [0002] The semi-submersible drilling platform is an offshore structure used for drilling wells, mainly including drilling, power, communication, navigation and other equipment, among which the upper part is the working deck, and the lower part is two lower hulls connected by supporting columns. [0003] Drilling equipment includes drilling equipment, power equipment, cementing equipment, oil testing equipment, lifting, mooring equipment and other auxiliary equipment, among which drilling equipment mainly includes blowout preventer unit, riser, LMRP and other auxiliary equipment. [0004] The key well control equipment of the blowout preventer group is BOP, which is a blowout preventer, which is a safety sealing wellhead device used to close the wellhead during oil test...
