Offshore Structural Steel

Primarily, offshore structures are constructed particularly for drilling oil and gas deposits deep under the seabed. Although applications will differ, all will have exposure to the effects of saltwater corrosion, strong sea currents often dictated by the strong winds and tides. Masteel’s search for natural fuel resources has extended into even more remote regions, for instance, the Arctic which also has led to rigs drilling at much greater depths and therefore lower temperatures.

Requirements of Offshore Structural Steel

Structures in challenging working environments like these demand a specific range of steels in order to promote longer working life, better safety, and to lower the risk of failure, which, in certain cases, could turn out to be disastrous.

Offshore Steel Characteristics

  • Low phosphorus and sulfur contents
  • Excellent weldability
  • Good internal soundness
  • High yield strength (355 N/mm2)
  • High resistance to lamellar tearing
  • Good resistance to brittle fracture (longitudinal and traverse)

Masteel UK Limited provides an extensive range of carbon steel plate for offshore applications. Masteel’s steel range is a natural progression of the more standard structural steels found in day-to-day life such as the construction industry.
