Abstract

A platform and a system including the platform are used for a ram blowout preventer including a bonnet and/or one or more components adjacent the ram blowout preventer. The platform includes a frame with a deck supported within the frame, and a support structure coupled to the frame to support the platform on the bonnet of the ram blowout preventer. The platform may further include a connector to removably couple the platform to the bonnet of the ram blowout preventer.

First claim

What is claimed is:

1. A platform for a ram blowout preventer comprising a bonnet, comprising:
a frame including a deck supported within the frame;
a support structure coupled to the frame and configured to support the platform on top of the bonnet horizontally mounted to a body of the ram blowout preventer, the support structure comprising a rounded cutout formed therein and configured to engage the top of the bonnet to secure the frame to the bonnet of the ram blowout preventer; and
a connector configured to removably couple the frame to the bonnet of the ram blowout preventer.

2. The platform of claim 1 , wherein the deck supported within the frame includes a first deck and a second deck with a gap formed between the first deck and the second deck.

3. The platform of claim 2 , further comprising a support arm extending across the gap between the first deck and the second deck.

4. The platform of claim 3 , wherein the connector is configured to removably couple the platform to the bonnet of the ram blowout preventer through the support arm.

5. The platform of claim 1 , wherein the deck comprises a grating, and wherein the grating comprises fiberglass resin.

6. The platform of claim 1 , further comprising a retainer to removably couple the deck to the frame.

7. The platform of claim 1 , further comprising an attachment point to support and transport the platform, wherein the attachment point comprises a swivel eye.

8. The platform of claim 1 , wherein the support structure is positioned below the frame, wherein the support structure extends from one side of the frame to another side of the frame.

9. The platform of claim 8 , wherein the support structure comprises a central portion with a first side portion angled and extending from the central portion to the one side of the frame and a second side portion angled and extending from the central portion to the other side of the frame.

10. The platform of claim 1 , wherein the connector is configured to removably couple the platform to pre-existing tie-down points formed within the bonnet of the ram blowout preventer.

11. A system, comprising:
a platform configured to be supported on top of a bonnet horizontally mounted to a body of a ram blowout preventer, the platform comprising a frame, a deck supported by the frame, and a rounded cutout formed in the platform and configured to engage the top of the bonnet to secure the platform to the bonnet of the ram blowout preventer.

12. The system of claim 11 , wherein the platform further comprises:
a support structure coupled to the frame and configured to support the platform on the bonnet of the ram blowout preventer, wherein the rounded cutout is formed in the support structure; and
a connector configured to removably couple the frame to the bonnet of the ram blowout preventer.

13. The system of claim 12 , wherein the connector is configured to removably couple the frame to pre-existing tie-down points formed within the bonnet of the ram blowout preventer.

14. The system of claim 12 , wherein the deck supported by the frame includes a first deck and a second deck with a gap formed between the first deck and the second deck.

15. The system of claim 14 , wherein the support structure comprises a central portion, a first angled side portion, and a second angled side portion, wherein the central portion is positioned below the gap, the first angled portion is positioned below the first deck, and the second angled portion is positioned below the second deck.

16. The system of claim 12 , wherein the deck supported by the frame includes a first deck and a second deck with a gap formed between the first deck and the second deck; and further comprising a support arm extending across the gap between the first deck and the second deck.

17. The system of claim 16 , wherein the connector is configured to removably couple the platform to the bonnet of the ram blowout preventer through the support arm.
