Offshore Steel Plate and Offshore Structural Steel

Predominantly, offshore structures are built specifically for drilling oil and gas deposits deep under the sea bed. Whilst applications will vary, all will have exposure to the effects of salt water corrosion, powerful sea currents often dictated by the tides and strong winds. Our search for natural fuel resources has stretched into even more inaccessible areas such as the Arctic which has also resulted in rigs drilling at much greater depths and hence lower temperatures.

Requirements of Offshore Structural Steel

Structures in harsh working environments like these require a specific range of steels to promote greater safety, longer working life and reduce the risk of failure which in certain cases could prove disastrous.

Offshore Steel Characteristics

Following are the characteristics of offshore steel:

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

Masteel UK Limited supplies a wide range of carbon steel plate for offshore applications. Our steel range is a natural progression of the more standard structural steels found in everyday life such as the construction industry.
