Abstract

A shroud system for a tubular string clamping device on a well platform is provided. The clamping device has a door pocket. The shroud system includes a cover frame and a cover door. The cover frame is configured to engage with the door pocket of the clamping device. The cover frame is also configured to define an access opening relative to the door pocket for access to an interior of the tubular string clamping device. The cover door is pivotally attached to the cover frame, and is pivotable between an open position and a closed position. The cover frame and the cover door are configured such that in the open position the access opening is uncovered thereby providing a passage through the door pocket and into the interior of the tubular string clamping device, and in the closed position access opening is covered by the cover door.

First claim

1 . A shroud system for a tubular string clamping device on a well platform, the clamping device having a door pocket, the shroud system comprising:
a cover frame configured to engage with the door pocket of the clamping device, and the cover frame is configured to define an access opening relative to the door pocket for access to an interior of the tubular string clamping device; and a cover door that is pivotally attached to the cover frame, wherein the cover door is pivotable between an open position and a closed position; wherein the cover frame and the cover door are configured such that in the open position the access opening is uncovered thereby providing a passage through the door pocket and into the interior of the tubular string clamping device, and wherein in the closed position access opening is covered by the cover door.

2 . The shroud system of claim 1 , wherein the cover frame includes a first enclosure panel disposed on a first lateral side of the access opening, and a second enclosure panel that is disposed on a second lateral side of the access opening.

3 . The shroud system of claim 2 , wherein the cover frame includes a first lateral side panel that is attached to the first enclosure panel and that extends laterally outward from the first enclosure panel, and a second lateral side panel that is attached to the second enclosure panel and that extends laterally outward from the second enclosure panel.

4 . The shroud system of claim 3 , wherein the cover door extends between the first enclosure panel and the second enclosure panel.

5 . The shroud system of claim 1 , wherein the cover frame includes a first lateral side panel that extends in a first lateral direction from the access opening and a second lateral side panel that extends in a second lateral direction from the access opening.

6 . The shroud system of claim 1 , wherein the cover door includes a base end and a distal end, wherein the cover door is pivotally attached to the cover frame adjacent the base end.

7 . The shroud system of claim 6 , wherein the cover door includes a wall section and a top section;
wherein the wall section extends from the base end to the top section, and the top section extends from the wall section to the distal end; wherein in the closed position, the wall section covers at least a portion of a wall portion of the access opening and the top section covers at least a portion of a top portion of the access opening.

8 . The shroud system of claim 6 , further comprising a flexible member attached to the distal end, wherein the flexible member is configured to engage with a tubular string disposed within the tubular string clamping device when the cover door is disposed in the closed position.

9 . The shroud system of claim 1 , further comprising a seal member configured to engage with a tubular string disposed within the tubular string clamping device when the cover door is disposed in the closed position.

10 . The shroud system of claim 1 , further comprising an actuator that is controllable to pivot the cover door between the open position and the closed position.

11 . A shroud system for a well drilling platform system, the well drilling platform system including a tubular string clamping device and a control line manipulating arm (CLMA) device, wherein the tubular string clamping device has a door pocket and is controllable to clamp a tubular string, and the CLMA device includes an arm that may be pivoted between an arm-up configuration and a docked configuration, the shroud system comprising:
a clamping device shroud that includes:
a cover frame configured to engage with the door pocket of the clamping device, and the cover frame is configured to define an access opening relative to the door pocket for access to an interior of the tubular string clamping device; and
a cover door that is pivotally attached to the cover frame, wherein the cover door is pivotable between an open position and a closed position;
wherein the cover frame and the cover door are configured such that in the open position the access opening is uncovered thereby providing a passage through the door pocket and into the interior of the tubular string clamping device, and wherein in the closed position access opening is covered by the cover door; and
a seal device attached to the arm of the CLMA device, wherein the seal device is configured to engage with a tubular string disposed within the tubular string clamping device when the arm of the CLMA device is disposed in the docked configuration.

12 . The shroud system of claim 11 , wherein the seal device is disengaged with the tubular string when the arm of the CLMA device is disposed in the arm-up configuration.

13 . The shroud system of claim 12 , wherein the seal device includes a slot that is configured to receive the tubular string when the arm of the CLMA device is in the docked configuration.

14 . The shroud system of claim 10 , wherein the seal device includes a first seal segment and a second seal segment that are configured to be disposed in a closed configuration in which the first seal segment and the second seal segment are engaged with the tubular string, or in an open configuration in which the first seal segment and the second seal segment are not engaged with the tubular string.

15 . The shroud system of claim 14 , wherein the first seal segment and the second seal segment are pivotally mounted and are configured to pivot between the closed configuration and the open configuration.

16 . The shroud system of claim 15 , further comprising a seal member actuator that is controllable to actuate the first seal segment and the second seal segment between the closed configuration and the open configuration.

17 . The shroud system of claim 11 , wherein the cover door includes a wall section and a top section;
wherein the wall section extends from the base end to the top section, and the top section extends from the wall section to the distal end; wherein in the closed position, the wall section covers at least a portion of a wall portion of the access opening and the top section covers at least a portion of a top portion of the access opening.

18 . The shroud system of claim 11 , further comprising a flexible member attached to the cover door, wherein the flexible member is configured to engage with a tubular string disposed within the tubular string clamping device when the cover door is disposed in the closed position.

19 . The shroud system of claim 11 , further comprising an actuator that is controllable to pivot the cover door between the open position and the closed position.

20 . A shroud system for a tubular string clamping device on a well platform, the clamping device having a door pocket, the shroud system comprising:
a pivotally mounted cover door that is disposable in an open position and in a closed position, wherein in the open position the door pocket is uncovered thereby providing a passage through the door pocket and into an interior of the tubular string clamping device, and in the closed position the cover door is disposed to cover the door pocket; and an actuator controllable to actuate the cover door between the open position and the closed position.
