Offshore & Marine Structural Steel
Offshore and marine steels combine strength, weldability, toughness and fatigue performance for structures exposed to dynamic loading and aggressive environments.
Engineering basis
Low-carbon fine-grain and TMCP steels dominate modern offshore structures; higher-strength quenched-and-tempered grades are also used.
Standards, grades or methods
API 2W/2H/2Y families, EN offshore grades, classification-society shipbuilding grades such as AH/DH/EH series and project-specific NORSOK/DNV requirements may apply.
Typical applications
Platforms, jackets, topsides, FPSOs, ships, offshore wind foundations, subsea structures and marine terminals.
Critical checks
Check through-thickness properties, CTOD/Charpy toughness, weld heat input, fatigue class, lamellar-tearing resistance, corrosion allowance, coating and cathodic protection.
Good engineering practice
Use the current governing code or specification and verify manufacturer data, material traceability and project-specific requirements. Where safety, pressure containment or structural integrity is involved, obtain approval from the responsible engineer before changing material, process or acceptance criteria.
