Polymer Seals and Materials for Energy Turret Systems

Due to an increase in deep water production projects, a key technology that has emerged is the use of FPSO (floating production, storage and offloading) vessels, which use turret swivel stack systems that are rather large in size and complexity.  Internal turret mooring systems allow FPSOs to remain on location permanently, even in very harsh environmental conditions, and allow the vessel to be disconnected from its moorings to avoid severe weather, sea conditions and icebergs.

Our OmniSeal® seals with back-up rings handle these larger diameter sealing systems with ease.   We developed a flexible and highly scalable technique to manufacture large diameter sealing systems, incorporating rings in Meldin® 5000 (PEEK based materials) that use a patent-pending, bending/welding/sintering process without any limitation in diameters.
