Plexus Holdings PLC / Index: AIM / Epic: POS / Sector: Oil equipment & services 10 February 2014 Plexus Holdings PLC (Plexus or the Company) Wintershall 3 Year Contract Renewal for Supply of POS-GRIP Wellhead Equipment Plexus Holdings PLC, the AIM quoted oil and gas engineering services business and owner of the proprietary POS-GRIP(r) friction-grip method of wellhead engineering, known for its safety, time and cost saving capabilities announces that it has subject to final contract details renewed for a further three years its supply contract with leading oil and gas company Wintershall Noordzee B.V for surface wellhead and mudline equipment services for exploration activities in the North Sea, offshore the Netherlands. Under the terms of the contract, Plexus will initially supply its 10,000psi POS-GRIP wellhead systems for two wells that will be operating at pressures of up to 3,500 psi.

The initial contract revenues are expected to commence fourth quarter financial year 2014. Plexus CEO Ben Van Bilderbeek said, "We are delighted to have renewed this contract with Wintershall for the supply of our pioneering POS-GRIP wellhead systems known for safety, time and cost saving benefits.

Having worked together since 2009, Wintershall is a long-standing and valued customer.

We believe due to the increased level of activity in the Dutch North Sea region, this renewed contract will bring further wellhead supply opportunities for both our standard pressure, and potentially for the first time High Pressure / High Temperature wellhead rental supply.

With this in mind, I look forward to providing updates on our progress in due course." **ENDS**

Notes to Editor Plexus Holdings PLC, which began trading on AIM in December 2005, is an oil and gas engineering and services business, which supplies wellhead and mudline suspension equipment for exploration and production applications.

Based in Aberdeen, with offices in London, Cairo, Kuala Lumpur and a presence in Houston, Texas, it has developed and patented a friction-grip method of engineering for oil and gas field wellheads and connectors, POS-GRIP(r), which involves deforming one tubular member against another to effect gripping and sealing.
The Company plans to accelerate the roll out of POS-GRIP wellhead equipment as a superior alternative to current technology and for it to become the future industry standard for wellhead design.

In particular, the technology has advantages in High Pressure/High Temperature (HP/HT) and Extreme HP/HT (X-HP/HT) oil and gas environments, for which there is growing global demand and where Plexus is being increasingly recognised as the supplier of choice.

Importantly, the Company is focussed on extending its proprietary technology into an increasing number of subsea applications.

In line with this, in March 2011 the Company launched an initiative to develop a new subsea wellhead design, HGSS(tm), utilising its friction-grip technology in collaboration with key oil and gas operators and service companies.

Royal Dutch Shell, Wintershall, Maersk, Tullow Oil, ENI, Oil States Industries Inc., TOTAL and the UK entity of the worlds largest offshore drilling company have joined the initiative to date.

The HGSS subsea wellhead design will include a combination of key features never before seen in a subsea wellhead which include being rated to 15,000 psi, 4,000,000 pounds of instant casing lockdown capacity, annulus pressure monitoring and access for bleed off capability to address sustained casing pressure (SCP) issues which are recognised by the API as a serious industry problem, and rigid metal annular seal technology qualified to match the performance of premium casing.

The design process has now been completed, and prototype testing is due for completion mid 2014.
To date, POS-GRIP wellhead systems have been used or selected to be used in over 300 oil and gas wells by international companies including Apache Energy Australia, BHP Billiton, BG International, Bowleven plc, BP, Brunei Shell Petroleum, Cairn Energy, Centrica, ConocoPhillips, Dana Petroleum, Dubai Petroleum, GDF SUEZ, Global Santa Fe, Maersk, Niko Resources, Petro-Canada Trinidad & Tobago, Red Sea Petroleum Operating Company, Repsol, RWE, Senergy Limited, Shell Egypt, StatoilHydro, Silverstone Energy, Talisman Energy, Tullow Oil, and Wintershall.
