Patent number: 9222317Abstract: The present invention is directed to novel methods and apparatus for the design, installation, use, recovery, and reuse of a Self Supporting Riser (SSR) for wells that are not under a platform. The SSR of the present invention uses standardized joints that can be recovered, potentially warehoused, and recombined in different configurations for different purposes or locations. Emphasis is on methods and apparatus that use relatively small vessels subject to high motions in the installation, use and recovery of the SSR. The SSR is adapted for high current and/or deep water applications for purposes of downhole well intervention and subsea equipment installation. In contrast to the apparatus and processes of the prior art, this invention addresses a comprehensive system design.Type: GrantFiled: September 20, 2012Date of Patent: December 29, 2015Assignee: My Technologies, L.L.C.Inventor: Charles R. Yemington

Publication number: 20140060415Abstract: The present invention is directed to a system including a self supporting riser (SSR) which is connected to a well to produce fossil hydrocarbon reservoirs deep below the seafloor. The SSR is constructed of a plurality of joints comprising regular joints and specialty joints that define the SSR and are selected to optimize the SSR for a well in a specific location. A unique aspect of the SSR of the present invention is that while capable of connecting to the wellhead, or tree on the seafloor, it can also be secured to an anchor during operations. The invention is further directed to a small vessel moored to the SSR by a line such as a hawser, the riser providing an anchor to the vessel, and the SSR carrying fluids from the well to the vessel and from the vessel to the well. The vessel has provisions for processing the fluids from the wellhead.Type: ApplicationFiled: November 8, 2013Publication date: March 6, 2014Applicant: My Technologies, L.L.C.Inventor: Charles R. Yemington

Publication number: 20140048276Abstract: The present invention is directed to a system including a self supporting riser (SSR) which is connected to a well to provide fluid communication to fossil hydrocarbon reservoirs deep below the seafloor. The SSR is constructed of a plurality of joints comprising regular joints and specialty joints that define the SSR and are selected to optimize the SSR for a well in a specific location. A unique aspect of the invention is further directed to a small vessel subject to high vessel motions that permits a coil tubing/wire line system to be mounted on a stabilizer system mounted on the vessel. The riser extension that connects the vessel to the self supporting riser preferably has a telescopic joint/section that is designed for the heave of the vessel.Type: ApplicationFiled: October 21, 2013Publication date: February 20, 2014Applicant: My Technologies, L.L.C.Inventor: Charles R.

Publication number: 20130252493Abstract: The present invention is an apparatus and method directed to a variable buoyancy gas-can buoyancy module or buoy having a flexible barrier between a variable volume gas chamber in the gas-can hull and water in the hull. More specifically, the present invention is directed to a variable buoyancy module for a Self Supporting Riser (SSR) wherein the tension in the SSR may be increased/decreased by increasing/decreasing the variable volume of a chamber formed by a flexible liner that provides a barrier between the variable volume gas chamber in the gas-can hull and water.Type: ApplicationFiled: May 6, 2013Publication date: September 26, 2013Inventor: Charles R.

Patent number: 7708839Abstract: The present invention is directed to a pig receiver used in a dewatering method for subsea pipelines. In the dewatering method a pig is placed in one end of the pipeline filled with water and a compressed gas is introduced behind the pig; in addition the water and pig are drawn by a subsea pump operated by a submersible vehicle (SV) operating near the sea floor to a pig receiver of the present invention. A feature of the pig receiver is a gas sensor that shuts the pump off when gas enters the receiver to prevent a gas (vapor) lock of the pump.Type: GrantFiled: June 15, 2005Date of Patent: May 4, 2010Assignee: Valkyrie Commissioning Services, Inc.Inventor: Charles R.
