Trelleborg’s subsea solutions, including its recently re-branded portfolio of thermal insulation materials and subsea seals, will be on display at the 2014 ONS Exhibition and Conference in Stavanger, Norway.
Trelleborg Sealing Solutions and Trelleborg Offshore & Construction will showcase products including thermal insulation solutions, Vikotherm and the multi-contact Turcon Variseal.
Vikotherm R2 consists of a three-layer coating system that provides protection against corrosion and hydrogen induced stress cracking (HISC). The material is suitable for jumpers and spool pieces; tie in spools, manifolds, subsea trees, risers and flowlines, joints, insulation covers and many more applications.
“As the offshore oil and gas industry continues to push the limits, flow assurance is becoming a critical element of deepwater developments,” said Ben Erik Jansen, Business Group Director of Trelleborg’s offshore operation. “This is resulting in a growing need for higher performance solutions which are guaranteed to perform in extreme environments.”
Jansen says Trelleborg’s Vikotherm portfolio caters to demanding environments, operating effectively at depths as low as 3000m+ (9843ft+) and at extreme temperatures ranging from -49°C to +115°C (-56°F to +311°F), which assures that oil and gas can flow through pipelines when required
The multi-contact Turcon Variseal from Trelleborg Sealing Solutions was developed to replace multiple chevron seals or V-stack type products in subsea valve stems requiring a high-integrity sealing capability. It includes a series of single-acting spring-energized seals housed within a U-shaped Turcon polytetrafluoroethylene (PTFE) based-material seal profile.
The Turconseal is designed to provide integrated redundancy, helping to extend the flex life of seals in high-pressure applications while providing better performance and lower operator costs. With the addition of anti-extrusion devices, the multi-contact Turcon Varisealcan withstand pressures of up to 207MPa/30,000psi.
“The unique single-piece design significantly improves sealing integrity and leak tightness in high-pressure applications by providing higher contact force across multiple seal hardware interfaces,” said Stuart Moares, Trelleborg Product Line Director.
ONS has established itself over 40 years as one of the world’s major meeting places for organizations within the oil and energy industry. The conference facilitates knowledge sharing and collaboration on major international issues with decision makers across the global energy industry.
