Title: Luiz Carlos De Lemos Junior: Innovator in Subsea Technology

Introduction

Luiz Carlos De Lemos Junior is a prominent inventor based in Rio de Janeiro, Brazil. He has made significant contributions to subsea technology, holding a total of 8 patents. His innovative work focuses on enhancing the efficiency and safety of subsea operations.

Latest Patents

One of his latest patents involves subsea risers. This invention describes a subsea catenary riser that consists of a rigid riser pipe suspended from a floating support on the surface. The riser extends through a sagbend to the seabed, featuring a hang-off interface that allows for rotation or pivoting of the riser pipe relative to the support. Additionally, a subsea buoy is positioned on the riser pipe above the sagbend, applying buoyant upthrust force to the riser pipe. This design enables the riser pipe to deflect with S-shaped curvature in response to movement of the support, thereby varying the inclination of the riser pipe portion attached to the buoy.

Another notable patent focuses on monitoring squeeze pressure of track tensioners. This tensioner system is designed to hold back elongate products, such as subsea pipelines, being laid into water. The system comprises at least one endless circulatory track supported by an array of rollers, with each roller mounted for rotation around a respective shaft. Notably, at least one of the shafts includes a load pin that senses loads applied to the surrounding roller in directions normal to its axis of rotation.
