Title: Innovations by Henri Rousseau in Subsea Technology
Introduction
Henri Rousseau, an accomplished inventor based in Paris, France, has made significant contributions to subsea technology through his innovative solutions. With a total of two patents to his name, Rousseau focuses on enhancing the reliability and efficiency of subsea pipe-in-pipe systems.
Latest Patents
Rousseau's latest patents include novel methods of sealing arrangements for subsea pipe-in-pipe systems. The first patent describes a technique for sealing an annulus in an electrically trace-heated pipe-in-pipe structure by introducing a flowable filler material to mold a sealing mass in situ. This sealing mass not only closes a restriction in the annulus but also embeds heating elements that extend longitudinally through the restriction. The design comprises an inner ring spaced within an outer ring, defining the annulus, which is then narrowed radially by projections extending into the annulus from either ring.
The second patent similarly addresses sealing an annulus between the inner and outer pipe sections of a pipe-in-pipe system. This method involves positioning a sealing mass in contact with both pipe sections and deforming the mass through shearing and compression during relative longitudinal movement. By fixing the inner and outer sections against reverse longitudinal movement, Rousseau ensures the sealing mass maintains its deformation. The design incorporates inclined ramp surfaces from respective pipe sections to facilitate the compression of the sealing mass.
