Korean steelmaker POSCO has received approval from DNV, the world's leading certification authority in the energy sector, as the first global steel company to produce plate for wind power.
POSCO and DNV signed a memorandum of understanding (MOU) for the certification of steel products applied in the wind power sector' and started the certification process in March.
DNV intensively inspected and evaluated the quality management system, production process and facilities, product testing facility, and related certifications of the Gwangyang Works' plate plant, which produces eco-friendly ‘Greenable’ plates for about three months and approved it as a 'Shop approval in renewable energy' in July.
In addition, it has certified the 'EN-S355' standard plate product that implemented the world's first uniform yield point (YP) made at Gwangyang Works as a 'Type and component certification of wind turbines'. POSCO's uniform yield point product is the first thick-plate product certified by DNV as a steel for renewable energy.
