OmniSeal® Spring-Energized Seals on World's First Subsea Gas Compression Station

In 2015, the world’s first subsea gas compression station will be installed in the Åsgard field offshore Norway. Saint-Gobain Seals’ high-performance OmniSeal® spring-energized seals have been certified for the axial control valves portion of the gas compression systems that will go on stream at a water depth of 3,000m on this station.

According to API6A PR2 testing, the seals successfully completed a 500,000 strokes endurance testing without leakage. The seals were custom-designed and manufactured with a unique blend of Saint-Gobain Seals’ Fluoroloy® material at the plant in Kontich, Belgium.

Developed in Norway, subsea compression technology improves gas recovery and provides many benefits compared to the alternative of a new platform install, including reduced investments and operating costs, a smaller environmental footprint and safer operations. This technology has great potential to change offshore gas field developments worldwide and is forecasted to grow in subsea developments, having even more impact as projects move into deeper waters further from shore.
