Offshore Platform/Topsides

The topside of an oil rig encompasses the surface deck of a platform, which includes all equipment for drilling, production and processing. It also includes the structure itself, literally any elements of the oil rig which are on the “topside” of the water line.

The topside operation can include oil and gas treatment, storage and offloading, process support systems, as well as the living quarters for those that work on the rig. All components in a topside construction must be suitable to perform in the hostile environments experienced at sea. Topside constructions must be able to cope with a full range of extreme conditions from arctic cold, to high temperature applications in the gas treatment process. Some platforms are floating production facilities with hulls much like a ship. To the untrained eye, they appear to have thick legs that extend to the seafloor. These legs are in fact the hull itself, with the platform held in place by the buoyancy of this hull and tendons (tension legs), which secure the structure to the seabed.

Edgen Murray and HSP valves have a long history of supplying components for topside constructions. We supply pipe, plate, welded tubulars and sections, as well as fittings, flanges and valves. Materials such as carbon, low temperature carbon, stainless steel, duplex and super duplex pipe, fittings, flanges and nickel alloy are all available. All steels that are suitable for topside usage as offshore construction grades, for example S355G15 +N/M and API 5L X52, or chrome-moly steel is also available specifically for high temperature processing operations. All materials can be supplied to EN, API, ASTM, ASME, ISO, JIS, AS, NORSOK and other international standard.

Our commitment to our supply process can only be matched by our commitment to provide excellent support services for your project. We go beyond material supply to offer project management expertise for single products to the most complex material packages. Technical consultation, custom manufacturing, material processing, and testing and finishing services are provided internally or coordinated through quality third-party providers.
