Offshore plant refers to offshore or seabed structures and is classified into drilling unit, production unit, multipurpose unit, fixed platform, floating type unit and compliant type. Required specification differs according to function and structure, It is extremely important to select appropriate steel type, develop new steel type, and secure welding conditions and physical properties.

Offshore construction involves strict management of standards and steel materials used according to specification required on structures (toughness, strength and CTOD of basic material and welded part). There are various offshore standards to guarantee such specification including European Standard (EN), British Standard (BS), API Standard, NORSOK, ASTM and DEP (Shell). There are active research efforts on offshore standard certification for new steel types, selection and development of appropriate welding materials, and securing of physical properties.
