Patent number: 8464795Abstract: An annulus isolation valve comprises a valve actuation bore and a flow passage capable of providing fluid communication between an upper annulus and a lower annulus. The flow passage comprises a first flow path and a portion of the valve actuation bore. Further, the first flow path has a second longitudinal axis that is different from a first longitudinal axis. The annulus isolation valve further includes a plug gate positioned in the valve actuation bore. The plug gate is configured so that in the open position it allows fluid communication between the upper annulus and the lower annulus. The annulus isolation valve further includes a biasing mechanism positioned in the valve actuation bore. The biasing mechanism is capable of forcing the plug gate into the closed position when the actuation force is not applied.Type: GrantFiled: August 19, 2009Date of Patent: June 18, 2013Assignee: Aker Solutions Inc.Inventors: Andy Dyson, Charles Li, Oystein Mogedal, Paulo Cezar Silva Paulo, Casey Russell, Nick Newlands

Patent number: 8376057Abstract: A wellhead assembly including a wellhead housing. The wellhead housing comprises a throughbore having a recessed sealing area and a tubing hanger positioned in the throughbore. A seal is positioned between the wellhead housing and the tubing hanger, the seal being positioned so as to form a gap between the seal and the wellhead housing. The wellhead assembly can further include a seal energizer capable of moving relative to the seal in a manner that forces the seal against the wellhead housing to bridge the gap. A method of installing a tubing hanger into a throughbore of a wellhead housing is also disclosed.Type: GrantFiled: August 19, 2009Date of Patent: February 19, 2013Assignee: Aker Subsea Inc.Inventors: Andy Dyson, Charles Li, Oystein Mogedal, Paulo Cezar Silva Paulo, Nick Newlands

Patent number: 8256506Abstract: A tubing hanger for use in a wellhead. The wellhead includes a throughbore, a landing seat positioned in the throughbore, a landing groove positioned above the landing seat in the throughbore, and a locking groove in the throughbore. The tubing hanger comprises an expandable landing ring positioned on the tubing hanger for engaging the landing groove and a landing mechanism for expanding the landing ring radially outward from the tubing hanger. A locking ring for engaging the locking groove can be positioned on the tubing hanger. The tubing hanger can further include a locking mechanism for expanding the locking ring radially outward from the tubing hanger body and locking it into the locking groove.Type: GrantFiled: August 19, 2009Date of Patent: September 4, 2012Assignee: Aker Subsea Inc.Inventors: Andy Dyson, Charles Li, Oystein Mogedal, Paulo Cezar Silva Paulo, Nick Newlands

Patent number: 7976084Abstract: A light weight lifting tool (10) for lowering and retrieving subsea equipment to and from the sea bed is disclosed. The equipment includes an upper coupling part in the form of a connector spool piece (15) having at least one circumferential ring groove (16) for use in making engagement with the lifting tool (10). The lifting tool (10) includes a housing (1) designed to enclose and receive the connector spool piece (15). The lifting tool (10) further includes a number of latch segments (8) having at least one radially inwards directed projection (8?) designed for engagement with the at least one ring groove (16), and an activating device (6) arranged to bring the latch segments (8) in and out of engagement with the at least one ring groove (16) by operation of the activating device (6).Type: GrantFiled: November 1, 2006Date of Patent: July 12, 2011Assignee: Aker Kvaerner Subsea ASInventors: Knut Møgedal, Øystein Møgedal

Patent number: 7637325Abstract: A cap for a subsea tree having a re-entry hub (1) and for use with a tubing hanger (25) deployed within the tree comprises an outer sleeve (3) for fitment over the hub and an inner sleeve (19) adapted to extend within the hub. The sleeve has communication couplers (27, 37) for cooperation with the tubing hanger. Preferably the communication couplers are located at the extremity of the inner sleeve. The couplers can accommodate dummy plugs or live couplers to suit the mode of application. The inner sleeve (19) supports at least one annular seal (21, 22) which provides a barrier between the inner sleeve and the inner periphery of the hub. The outer sleeve (19) includes releasable engagement fittings (16) for securing the outer sleeve to the hub. The cap is adapted for use as a running tool.Type: GrantFiled: October 17, 2006Date of Patent: December 29, 2009Assignee: Aker Subsea LimitedInventors: Cecil C Goonetilleke, Oystein Mogedal, Knut Mogedal
