Title: Innovations by Dennis Earl Calkins
Introduction
Dennis Earl Calkins is an accomplished inventor based in Katy, TX (US). He holds two patents that showcase his innovative contributions to the field of engineering and technology. His work primarily focuses on tools and apparatuses designed for pipeline recovery and deep water operations.
Latest Patents
One of Calkins' latest patents is the Pipeline Recovery Tool. This tool is constructed from steel plates that are welded together, rather than being forged and machined. The design allows the tool to be lowered over a pipeline, where a fixed claw engages the collar of the pipeline. An ROV is utilized to engage a movable dog on the tool, locking the fixed claw in position. Once the rigging on the fixed claw side is released, the pipeline can be lifted to the surface using a lift arm on the tool's first end.
Another significant invention is the Deep Water Lowering Apparatus. This apparatus features dual davit structures mounted on a barge, each equipped with a pulling wire rope line spooled on a storage winch. The pulling lines are reeved onto a traction winch and through upper and lower sheaves on the davit structure. The ends of each pulling line are connected on an equalizer beam, allowing for efficient load transfer. An adaptor box is suspended from a spreader bar, facilitating the lowering of loads without the need for extensive rigging work.
