Patent number: 9845655Abstract: A method for testing an insert packer assembly positioned within a diverter assembly includes inserting a test tool through an opening of the insert packer assembly and into a bore of the diverter assembly. The method includes driving multiple annular flexible components of the insert packer assembly radially inward to contact an outer annular surface of the test tool to form a sealed space between the multiple annular flexible components and the outer annular surface of the test tool. The method also includes applying a fluid to the sealed space to increase a pressure within the sealed space and monitoring the pressure within the sealed space over a period of time to determine a condition of the insert packer assembly.Type: GrantFiled: October 1, 2015Date of Patent: December 19, 2017Assignee: Cameron International CorporationInventors: John Hoefler, Erman Citirik, James Chris Reed

Patent number: 9422789Abstract: A diverter system having stabbing dogs is provided. In one embodiment, such a system includes a diverter, a housing, and a plurality of stabbing dogs coupled to the housing. The stabbing dogs are positioned to enable locking elements of the stabbing dogs to be extended into recesses in the diverter to secure the diverter within the housing. At least one of the recesses in the diverter is connected to a fluid conduit within the diverter, and at least one stabbing dog includes a fluid passage that enables fluid to be routed into the fluid conduit within the diverter through the at least one stabbing dog. Additional systems, devices, and methods are also disclosed.Type: GrantFiled: June 27, 2015Date of Patent: August 23, 2016Assignee: Cameron International CorporationInventors: Jerod C. Bushman, John B. Hankins, John A. Hoefler, Harold A. Tenorio

Patent number: 9284796Abstract: A hang-off gimbal assembly to support a tubular member from an offshore drilling vessel. The hang-off gimbal assembly includes an axis therethrough and comprises a support plate including an opening formed about the axis, a base plate including an opening formed about the axis, and a plurality of shock absorbers between the support plate and the base plate. The hang-off gimbal assembly is movable between an open position and a closed position, such that, in the open position, the hang-off gimbal assembly is configured to receive the tubular member in the opening of the support plate and in the opening of the base plate, and in the closed position, the hang-off gimbal assembly is configured to enclose about and support the tubular member.Type: GrantFiled: December 18, 2013Date of Patent: March 15, 2016Assignee: Cameron International CorporationInventors: John Hoefler, Erman Citirik
