Title: The Innovative Contributions of Daniel Sahonero Rodrigues

Introduction

Daniel Sahonero Rodrigues is a notable inventor based in Rio de Janeiro, Brazil. He has made significant contributions to the field of subsea engineering, particularly in the installation and management of subsea risers and pipelines. With a total of 3 patents to his name, Rodrigues continues to push the boundaries of innovation in his industry.

Latest Patents

One of Rodrigues' latest patents is focused on the "Installation of subsea risers." This method involves placing an elongate negatively-buoyant support on the seabed. When laying the riser on the seabed, a riser portion is guided onto the support to extend along and be cradled by it. A hogbend region of the riser is then formed by conferring positive buoyancy on the support to lift both the support and the riser portion away from the seabed. The design includes a riser support disposed in a longitudinally extending open-ended gap between buoyancy volumes on opposite sides of the gap. Coupling formations, such as hinge portions, can couple the element to a like element, allowing for alignment of gaps to define an upwardly opening, longitudinally extending groove to receive the riser.

Another significant patent is related to "Pipe spooling for reel-lay operations." This innovation involves lined pipelines with different inner diameters being spooled successively onto a reel. The constituent pipe stalks are cyclically pressurized internally to combat wrinkling of the liner. A first, variable diameter pig is advanced to the trailing end of a first pipeline, and a transition joint is attached to effect a transition from the inner diameter of the first pipeline to that of a second pipeline. The first pig is then driven through the transition joint into the second pipeline, where its diameter changes to match the inner diameter of the second pipeline.
