Embodiment Construction

[0018] refer to figure 1 , a remotely operated vehicle (ROV) interface 11 has a permanent module comprising a housing 13 . Housing 13 has a front end 15 and a rear end 17 . The terms "front" and "rear" are arbitrary; the front end 15 is positioned to be more accessible to the ROV than the rear end 17 . Housing 13 may have an outer cylindrical flange 19 extending outwardly from front end 15 . In this embodiment, housing 13 is generally cylindrical and is mounted to a subsea well, such as subsea well panel 21 . The housing 13 is rotatable relative to at least a part of the panel 21 . Although shown upwardly, the front end 15 may be oriented in a horizontal or other direction.

[0019] A backing ring 23 may be secured to the outer diameter of the casing 13 and held against the subsea panel 21 . A portion of the panel 21 fits between the flange 19 and the collar 23 . Other ways of mounting the casing 13 to the subsea well arrangement are possible. The shell 13 is considered...

Abstract

The invention relates to a remote operated vehicle interface with shear element. A remote operated vehicle (ROV) interface for transferring torque from an ROV drive tool 84 to a shaft of a subsea well device 27. The interface comprising a permanent module 13 coupled to the shaft 27, a retrievable module with a drive part 77 and a driven part 43 coupled together by a shear element for rotation in unison. The driven member is releasably coupled to the permanent module. The drive member is engageable with the drive tool to cause the drive member, the driven member and the permanent module to rotate the shaft. There is an ROV retrieval profile on the retrievable module to enable the drive and driven members to be retrievable together by the ROV. The second invention is an ROV interface with a housing, a drive cavity, a pod cavity, and pod body, a spring biased retainer and a shear element.

Description

technical field [0001] The present disclosure relates generally to an interface for receiving a transmission tool of a ROV for rotating subsea equipment, such as a subsea valve actuator, and more particularly to an interface with an overtorque protection device. Background technique [0002] Subsea well installations, such as subsea trees, employ valves that are typically hydraulically or electrically actuated. Valve actuators typically have an override mechanism that allows the valve to be opened or closed manually rather than hydraulically or electrically. Manual actuation occurs in response to a transmission rod or shaft being rotated by an external device, such as a Remotely Operated Vehicle (ROV). Subsea well equipment may have other axes that are rotated by the ROV. The ROV is deployed on the umbilical from the surface vessel, and the ROV is controlled from the surface vessel. [0003] Valve actuators have components in their drive trains that can fail or become dam...
