Plexus Holdings plc is a United Kingdom-based company that is engaged in providing oil and gas engineering services. The Company offers products and services for the surface and subsea drilling and production markets. Its POS-GRIP technology is a patented method of engineering, which can be applied to a variety of oil and gas products, such as wellheads and connectors. The Company’s HG seals are metal-to-metal seals, which are machined directly into the hanger and are energized by the use of an external POS-GRIP mechanism. Its method of engineering for wellheads offers a range of advantages to operators, particularly for high-pressure high-temperature (HP/HT) applications. POS-GRIP technology can also be applied for surface land, and platform production and subsea wellheads. It has developed a range of products based on this technology and is focused on pursuing surface production, abandonment, subsea and geothermal wellhead opportunities, as well as connectors and the subsea market.
