Thermal insulation is necessary to avoid the formation of hydrate plugs and wax build-up in subsea structures. The build-up begins when the oil/gas composition temperature is not maintained and begins to cool. Without thermal insulation the cold seawater rapidly cools down the oil, forming hydrate/wax blockages, making it impossible for a safe flow. Thermal insulation materials prevent formation of these blockages during a shutdown scenario or during normal operations. Trelleborg Offshore offers a range of materials for wet insulation systems.
High level performance for world’s first subsea gas compression facility
Located on the Halten Bank in the Norwegian Sea, about 200 km from mid-Norway, Åsgard is a central hub and a significant oil and gas producer. It is also the first field in the world to use seabed gas compression. The decision to adopt this new technology on the Åsgard field is expected to maintain production and an increased recovery equivalent to approximately 278 million in barrels of oil when the project is realized.
Located roughly 60 miles offshore Nigeria, the Erha North phase two development sits at 3,960 feet / 1,200 meters deep and is an extension of the existing Erha subsea system and infrastructure. The existing system is currently producing to the Erha floating production, storage and offloading (FPSO) vessel
