• For over 30 years, Plexus has been protecting the environment, initially with its "through the BOP" (Blow-out Preventer) wellhead designs, and subsequently with its proprietary leak-proof wellhead sealing system, POS-GRIP®.• Thanks to POS-GRIP technology, Net Zero leak-free performance can be guaranteed for the life of the well, reducing harmful methane emissions and unnecessary intervention costs.• This simple method of engineering, using sealing principles derived from Hertzian Stress Theory, has been independently verified and used by blue-chip oil and gas operators.• POS-GRIP technology helps operators to fulfil their ESG responsibilities.• Plexus has also signed a non-exclusive license with Cameron International Limited for POS-GRIP surface production wellhead technology, and are working alongside each other on the development of an inaugural low-cost wellhead design incorporating POS-GRIP.• In July 2021 Plexus received London Stock Exchange's Green Economy Mark in recognition of contributing to the global green economy and demonstrating alignment with Net Zero and ESG principles.
