| 20100163244 | RIGLESS ABANDONMENT SYSTEM - A rigless abandonment system including a surface vessel having an attached lifting device and a moonpool. The system further includes a cutting module configured to connect to a subsea wellhead, the cutting module having a wellhead connector having an actuatable lock and release mechanism, a motor assembly, and a cutter. An umbilical line connects the cutting module to the surface vessel, wherein the lifting device is used to raise and lower the cutting module connected to the surface vessel through the moonpool. A method for performing rigless casing cutting and wellhead removal operations, the method includes positioning a surface vessel above a subsea wellhead, where the surface vessel has a moonpool and a lifting device. The method further includes providing a cutting module, and deploying the cutting module through the moonpool, wherein the cutting module is connected to the surface vessel by an umbilical line. | 07-01-2010 |
| 20110088911 | EMBEDDED MULTI-STRING WELL HEAD SHEAR - The present disclosure generally provides apparatus and methods for removing a subsea well head. The apparatus may include an embedded shear comprising a pile and a shear cutter integrated into the pile. The shear cutter may be mounted within the pile near a lower end thereof. The pile may include a well head conductor receptacle adapted to receive a subsea well head, and the shear cutter may include a shear blade that extends across the well head conductor receptacle when activated. | 04-21-2011 |
| 20110100638 | Apparatus and Method for Cutting Tubular Parts Subsea - The present invention concerns an apparatus for cutting a tubular part ( | 05-05-2011 |
| 20120217018 | LASER ASSISTED BLOWOUT PREVENTER AND METHODS OF USE - There is provided a high power laser assisted blowout preventer and methods of use. In particular, there are provided systems and assemblies for utilizing high power laser energy within a blowout preventer to cut tubulars that are present within the bore of the blowout prevent, reducing the risk that such tubulars will inhibit the ability of the blowout preventer to seal a well. | 08-30-2012 |
| 20140000902 | REDUCED MECHANICAL ENERGY WELL CONTROL SYSTEMS AND METHODS OF USE | 01-02-2014 |
| 20140116717 | VALVE SYSTEM - A system and methodology facilitates utilization of a valve of a type which may be used as a subsea test tree. The valve comprises a valve element pivotably mounted in a housing having a passageway therethrough. The valve element may be actuated between an open position and a closed position blocking the passageway. A cutter is disposed along a first surface of the valve element and a seal system is positioned for engagement with a second surface of the valve element to provide separate cutting and sealing surfaces. Actuating the valve element from the open position to the closed position enables cutting of a conveyance, that may be positioned through the passageway, while simultaneously forming a seal along a separate surface to sealingly block the passageway. | 05-01-2014 |
| 20160186524 | SUBSEA IN SITU LASER FOR LASER ASSISTED BLOW OUT PREVENTER AND METHODS OF USE - High power sub sea, and sub sea in situ laser beam generation, assemblies and cutting operations for use in riser blowout preventer systems for off shore exploration and production of energy resources, including hydrocarbons. The system utilizes high power sub sea lasers to provide laser beams to laser cutters that are associated with a riser, a blowout preventer, or other sub sea structure. | 06-30-2016 |
