The deal is a part of the Plexus’ global strategy to expand its POS-GRIP wellhead equipment.

The agreement will bring together Plexus’ POS-GRIP method of engineering with Jereh’s manufacturing and sales and marketing skills, to work with COSL and RST on design, development, manufacture, supply, installation and provision of aftermarket services for subsea systems and crossover wellhead production systems.

Plexus CEO Ben Van Bilderbeek said: "This latest collaboration agreement is another significant milestone in this journey, and Jereh and Plexus look forward to designing and manufacturing a range of innovative shallow water oil and gas equipment solutions for the Chinese market where COSL has the largest fleet of offshore oilfield services facilities in China."

COSL is majority owned by Chinese state owned company CNOOC Group. Red Sea Technologies is an oilfield design and services company in South East Asia.
