Patent number: 11821564Abstract: A method and system for pipeline purging with reduced environmental impact. A vacuum and/or compressor system purges air or other gases from at least a section of the pipeline to create a vacuum in the pipeline. The vacuum can then be replaced with a fuel gas, avoiding a mixing of fuel and oxidant in the pipeline. The vacuum and/or compressor system can include a fuel gas monitoring leak-detection system to monitor for fuel presence in the purging air.Type: GrantFiled: September 21, 2021Date of Patent: November 21, 2023Assignee: OPERATIONS TECHNOLOGY DEVELOPMENT, NEPInventors: William Benincosa, Dennis R. Jarnecke

Patent number: 10801657Abstract: Systems and methods for shutting off or stopping fluid flow through a pipe are provided. An inflatable bag stopper assembly is inserted through an opening into the pipe. The assembly includes one or more inflatable bags with each inflatable bag having a check valve positioned at an inlet. In inflatable bag stopper assemblies of two or more inflatable bags, the inflatable bags are connected in series. The inflatable bag stopper assembly is inflated such that the inflatable bag or bags act or serve to obstruct, block, close, or otherwise effectively foreclose passage of the fluid through the pipe.Type: GrantFiled: February 23, 2018Date of Patent: October 13, 2020Assignee: OPERATIONS TECHNOLOGY DEVELOPMENT, NFPInventors: Jeffery W. Mainzer, Dennis R. Jarnecke

Patent number: 10571038Abstract: A breakaway coupling includes a body and a valve assembly inside the body. The body includes a fluid conduit and a shear groove between first and second portions. The shear groove is designed to crack, break, or separate under certain conditions. The valve assembly is designed to shut off fluid flow through the fluid conduit when the shear groove cracks, breaks, or separates. The valve assembly includes a valve seat, a sealing element, one or more pins, and a biasing member. The one or more pins hold the sealing element in an open position while the shear groove is in tack, and allow the sealing element to move to a closed position (with the help of the biasing member) in the event the shear groove cracks, breaks, or separates.Type: GrantFiled: July 17, 2018Date of Patent: February 25, 2020Assignees: OPW Engineered Systems, Inc., Operations Technology Development, NFPInventors: Joseph P Roth, Michael Crum, Dennis R. Jarnecke, Krzysztof Wejdman, Narendar Venkatachalapathy

Patent number: 9500311Abstract: A device and method for inserting a tool into a pipeline transporting a fluid. The device includes a housing that is attachable to a vertical fitting applied on the pipeline, and a launch tube supported by the housing and including a tool passageway through which a tool is fed. The launch tube moves relative to the housing to raise and lower a shoe at an end of the launch tube into the pipeline. The shoe is and adapted to insert a tool into the pipeline at an angle to the launch tube.Type: GrantFiled: November 5, 2014Date of Patent: November 22, 2016Assignee: Gas Technology InstituteInventors: Jeff Mainzer, Dennis R.

Patent number: 7179114Abstract: A tracer wire connector (10) having two parts, a main body (11) and a cover (12). The main body includes a base (16) and a raised portion (24) connected with the base, the raised portion forming a first groove (13) extending from one side of the base to an opposite side of the base, the raised portion forming an at least partially closed bore (14) having a closed off end (17) extending parallel to the first groove, and the raised portion forming a second groove (15) traversing the first groove and the bore. The cover forms a cavity (23) adapted to receive the main body and includes at least one cutting element (22) disposed within the cavity aligned to fit into the second groove upon insertion of the main body into the cover. Disposed within the cover is a displaceable insulating material which is displaced to fill empty space within the connector upon insertion of the main body into the cover.Type: GrantFiled: February 10, 2006Date of Patent: February 20, 2007Assignee: Gas Technology InstituteInventors: Pawel Kuzan, Dennis R.
