Title: Innovations by Blaise Seguin: Advancements in Subsea Buoyancy Systems

Introduction

Blaise Seguin, an accomplished inventor based in Paris, France, has made significant contributions to the field of subsea technology. With a portfolio of four patents, her innovative approach has paved the way for advancements in buoyancy systems, which are crucial for underwater structures such as pipeline bundles.

Latest Patents

Among her latest patents, Seguin has developed a method for providing buoyancy to subsea structures through the use of a rigid elongate buoyancy tube. This invention defines a floodable envelope designed to contain a mass of buoyant macrospheres. The tubular delivery system features multiple openings that facilitate fluid communication with a void extending between the macrospheres. When submerged, the void floods through these openings, allowing the macrospheres to apply buoyant upthrust to the surrounding buoyancy tube, which is rigidly attached to the subsea structure.

Another notable invention by Seguin focuses on controlling the buoyancy of a mass of buoyant spheres. This system involves a floodable envelope containing buoyant spheres and a void that extends between them. The envelope is equipped with openings that maintain fluid communication with the void. In a unique approach, destruction devices are incorporated to selectively destroy the spheres upon activation. This creates shockwaves that allow for the expansion of the void, which subsequently facilitates the admission of additional water into the envelope, thereby enabling effective ballasting of the buoyant element.
