Trelleborg Wins Two Awards for Engineering Innovation

Trelleborg has been awarded E&P Magazine’s prestigious Special Meritorious Awards for Engineering Innovation (MEA) in two categories.

SealWelding Technology

SealWelding ™ Technology from Trelleborg Sealing Solutions won in the category of Marine Construction and Trelleborg’s offshore operation won for its deployment of Firestop™ in the Floating Systems and Rigs Category. The MEA awards will be presented at the Offshore Technology Conference (OTC) in Houston, Texas.

SealWelding
David Brown, Global Lead Group Director, Oil & Gas, Trelleborg Sealing Solutions, says: “As a global leader in engineered solutions that seal, damp and protect, we are honored to have our SealWelding technology recognized for its revolutionary approach – enabling seals to be welded in situ on an FPSO platform eliminates the need for the oil & gas vessel to disconnect and return to shore. Our customers can now realize enormous cost and time savings due to our engineered innovations.”

SealWelding is a technology that allows seals to be welded on an FPSO platform, eliminating the need for it to disconnect and return to shore. Manufactured from Trelleborg’s well-established seal materials, this technology reduces the downtime and associated costs that come from maintaining an FPSO swivel stack.

Firestop
Hans Leo Hals, Managing Director for Trelleborg’s offshore operation based in Norway, says: “Since everyone involved in offshore oil & gas production knows that MEA entries are judged on their game-changing significance, both technically and economically, we couldn’t be more proud to have Firestop acknowledged for protecting floating systems and rigs. Providing fire safety for people, structures and equipment is something that we do and will continue to do through new innovations.

Our Firestop solutions ensure the integrity of structures are maintained in the event of a fire by providing time to evacuate people, close down critical equipment and for responders to gain control of the fire and evacuate an area.”Firestop™ is a rubber-based passive fire protection solution which can be customized to meet the demands of specific offshore oil and gas projects and installations. By using a layered construction, Firestop™ provides corrosion, thermal, fire and mechanical protection.

The MEA Awards
An independent team of experts, including engineers and engineering managers from operating and consulting companies worldwide, judged the competition. The winners come from a varied range of disciplines in oil & gas exploration and production, solving many of the issues that posed barriers to efficient operations. Technological advances of the winners open new and better avenues to the critical challenges the industry faces. The awards were presented on Trelleborg’s booth during the Offshore Technology Conference in Houston, Texas.

Trelleborg and Schoolhill in Pioneering Shah Deniz Project

Trelleborg Sealing Solutions has “pushed the barriers of science” to produce a “highly innovative” seal for a ground-breaking valve designed by Schoolhill Hydraulic Engineering for BP’s Shah Deniz field.

Schoolhill Hydraulic Engineering

The pioneering high flow, high integrity, safety critical subsea QEV (quick exhaust valve), believed to be the first of its kind, has been created for a subsea HIPPS (high integrity pressure protection system) at the South Caspian Sea site.

Quick exhaust valve
Trelleborg created a bespoke version of its Captive Glyd Ring® in its low friction Zurcon® Z43 high modulus thermoplastic to feature in the QEV, which was selected as the seal was required to slide across mating surfaces that had dimensional changes. The seal is retained in a split groove, which prevents the sealing surface from getting damaged by a counter part with variable diameter or when passing holes.

The QEV has a 30-year design life with a valve qualification water depth range of 3,000 meters and a safety integrity level (SIL) rating of SIL3 with 23,000 accumulated cycles.

Schoolhill Hydraulic Engineering
With a volume flow rate of 22 liters in five seconds (260 liters per minute), the device has been designed to ensure quick and safe emergency shutdowns on the ocean bed.

It is the culmination of a five-year project by Aberdeen-based Schoolhill Hydraulic Engineering. Trelleborg Sealing Solutions was commissioned to develop the seal.

Unique and innovative solution
David Brown, Global Lead Group Director Oil and Gas for Trelleborg Sealing Solutions, said: “Oil and gas exploration in hostile deepwater environments is demanding industry partners to continuously push the barriers of science in the pursuit of reliable and robust equipment.

“At Trelleborg, we pride ourselves on innovation and relished this opportunity to help create a high-pressure gas production valve for a HIPPS providing an extremely efficient shutdown. With huge volumes of fluid needing to rapidly exit via the system, we designed a unique sealing solution to maximize the performance of an already highly innovative product. We don’t believe another QEV of this type and performance is available anywhere else – it’s truly pioneering.”

Great future
Schoolhill Hydraulic Engineering Director Ronald Whyte said: “It seems a long time ago since we started this project. At the onset we knew we were taking on a lot, with the specifications we had to satisfy, notwithstanding the documentation and reporting required when working with a major oil and gas operator. It’s been a huge learning curve for Schoolhill, a small company with very limited financial resources.

“However, we are forward looking and believe that the step change provided by HIPPS for the oil and gas industry, will see many more operators going along this road. We believe this valve has a great future, which would not have been possible without the technical support provided by Trelleborg.”
