ClassNK has granted the class notation ‘a-EA (GRS)’ to Bright Queen, a bulk carrier operated by NYK Bulk & Projects Carriers Ltd., certifying the use of green steel.

According to ClassNK, this is the world’s first notation being granted for using green steel in a vessel.

There’s a growing focus on using green steel, which reduces GHG emissions in the manufacturing process, in ships as part of efforts to cut GHG emissions across the entire supply chain.

To support these advanced initiatives, ClassNK has released its ‘Environmental Guidelines,’ which set out notations for ships with advanced environmental measures, such as the ‘a-EA (GRS)’ notation to indicate the use of green steel in ship structures and other components.

For Bright Queen, built by Higaki Shipbuilding Co., Ltd., ClassNK confirmed the use of JFE Steel Corporation’s green steel ‘JGreeX’, for which ClassNK had conducted third-party certification of GHG emissions reductions in the manufacturing process, and granted the notation to the vessel.
