Title: Walter Greene: Innovator in Marine Subsea Technology
Introduction
Walter Greene is a notable inventor based in Houston, TX (US). He has made significant contributions to the field of marine subsea technology, holding 2 patents that showcase his innovative approach to engineering solutions.
Latest Patents
One of Walter Greene's latest patents is focused on marine subsea free-standing riser systems and methods. This invention involves a free-standing riser system that connects a subsea source to a surface structure. The system features a concentric free-standing riser comprising inner and outer risers that define an annulus between them. The lower end of the riser is fluidly coupled to the subsea source through a lower riser assembly (LRA) and one or more subsea flexible conduits. The upper end of the riser connects to a buoyancy assembly and the surface structure through an upper riser assembly (URA) and one or more upper flexible conduits. The riser is also mechanically connected to a buoyancy assembly that applies upward tension to it. Additionally, the riser may be insulated for flow assurance, either by using a flow assurance fluid in the annulus, insulating the outside of the outer riser, or both. The system may also include a hydrate inhibition system and/or a subsea dispersant system, with the surface structure potentially being dynamically positioned.
